The South Jersey growers, to whom early ripening fruit is the great desideratum and who have a very warm soil, and grow plants so they are quite hardy and can be transplanted with little check, set them in the field very early, some seasons by the last of April; and if the plants can be got out so as to have two or three days of favorable weather to get established before it comes, they seem to be little hurt even by a quite severe frost. The first essential to successful transplanting is to have well-grown, healthy, hardy plants; the second is that they be in good condition for setting, which can be secured by giving them, for a few days before planting, a scant supply of water and fullest possible exposure to air and sun, and then a thorough wetting a few hours before they are to be set.

Plants set in this way often do not wilt at all, even in hot sunshine. When plants are grown in boxes these can be taken to the field and plants taken from them in much the same way and so that they will be disturbed but little. In setting the plants it should always be borne in mind that while sunshine on the leaves of a plant rarely does any injury, it is very injurious to the roots, and the exposure of the roots to the sun or to cold, dry wind, should be avoided in every practicable way, such as by carrying the plants to the field laid on the sides of a box, which is then carried with its bottom toward the sun so as to have the plants in the shade, always handling the plant in the shade of one's body, etc. It is well worth while to walk to the end of the row to commence work in order to secure this. It is attention to such details that distinguishes one whose plants nearly always do well from one who loses a large proportion of those he handles.

Cultivation

Some growers transfer the pollen with a camel's-hair-brush; others by pulling off the corolla and adhering anthers and rubbing them over the stigma of other flowers. Fruit rarely follows flowers that are not pollinated, and if it is incomplete the fruit will be unsymmetrical and imperfectly developed. As tomato flowers secrete but very little, if any, honey and are not attractive to insects, it is of no advantage to confine a hive of bees in the tomato house in the way which is so useful in one where cucumbers or melons are growing.

Staking, Training and Pruning

Under favorable conditions of soil and climate, plants of most varieties of tomatoes will, in field culture, yield as much fruit if allowed to grow naturally and unpruned as if trained and pruned. This is especially true of the sorts of the Earliana type and on warm, sandy soils, while it may not be true of the stronger growing sorts, or on rich clay lands or where the fertilizer used contains an excess of nitrogen. In any case more fruit can be grown to the acre on pruned and staked plants because more of them can be gotten on an acre; and it is an advantage to grow them in that way because it enables us, by later cultivation, to keep the ground in good tilth longer; also it facilitates the gathering of the fruit; and last, but not least, it generally enables us to produce better ripened and flavored fruit.

Staking and pruning used to be the almost universal practice in the South, but in many sections growers have abandoned it, claiming that they get as good or better results without it. In the North it is rarely used in field culture, though often used in private gardens and by some market gardeners, and both staking or tying up and pruning are essential to the profitable growing of tomatoes under glass. In the South, stout stakes from 1 to 2 inches in diameter and 4 to 5 feet long are driven into the ground so that they can be depended upon to hold the plants erect through the heaviest storms, as seen in Fig. 21. This is generally and wisely done as soon as the plant is set, though some growers delay doing so until the fruit is well set, claiming that the disturbance of staking, tying and pruning tends to hasten the ripening of the fruit. The plant is then tied up, the tying material being wrapped once about the stake and then looped about the plant so as to prevent slipping on the stake or choking the stem of the plant as it enlarges. Raffia is largely used and is one of the best tying materials, but short pieces of any soft, cheap string can be used. The tying up will need to be repeated as the stem elongates, which it will do very rapidly.

In pruning the tomato we should allow the central shoot of the young plant to grow, and remove all of the side shoots which spring from the axils of the leaves and sometimes even from the fruit clusters, as seen in Fig. 22. It is very desirable that this be done when the branches are small, as there is then less danger of seriously disturbing the balance of the growing forces of the plant, and also because there is less danger of careless workmen cutting off the main shoot in place of a lateral, which would seriously check the ripening of the fruit. It is especially important that any shoots springing from the fruit cluster be removed as early as possible. For these reasons it is important that, if the plants are to be pruned at all, the field be gone over every few days. If the pruning is not well done it is a disadvantage rather than a help.

Some growers allow two or three instead of one shoot to grow, selecting for the second the most vigorous of the shoots starting from below the first cluster of fruit. In some locations they stop or pinch out the main shoot just above the first leaf above the third or fourth cluster; in some soils it is an advantage and in others rather a disadvantage to do this. I have seldom practiced it. When fruit at the lowest cost a bushel is the desideratum, neither pruning nor staking is desirable.

I have seen tomatoes grown very successfully by the side of an open fence. Two stakes were driven into the ground about 6 inches from the fence and the plant, but slanting outward and away from each other. The tops of the stakes were fastened to the fence by wooden braces, and then heavy strings fastened to the fence around the stakes and back to the fence, the whole with the fence forming a sort of inverted pyramidal vase about 3 feet across at the top. In this the plant was allowed to grow, but it would be essential to success that the fence be an open one.

Ripening, Gathering, Handling and Marketing the Fruit

Tomatoes ripen and color from within outward and they will acquire full and often superior color, particularly about the stems, if, as soon as they have acquired full size and the ripening process has fairly commenced, they are picked and spread out in the sunshine. The point of ripeness when they can be safely picked is indicated by the surface color changing from a dark green to one of distinctly lighter shade with a very light tinge of pink. Fruit picked in this stage of maturity may be wrapped in paper and shipped 1,000 or 2,000 miles and when unwrapped after two or ten days' journey will be found to have acquired a beautiful color, often even more brilliant than that of a companion fruit left on the vine. Enclosing the fruit while on the vine and about half grown in paper bags has been recommended, and it often results in deeper and more even coloring and prevents injury from cracking, but the fruit so ripened, while more beautiful, is not so well flavored as that ripened in the sun. But Americans are said to taste with their eyes, so that in this country, fruit of this beautiful color will often out-sell that which is of better flavor though of duller color.

The tomato never acquires its full and most perfect flavor except when ripened on the vine and in full sunlight. Vine and sun-ripened tomatoes, like tree-ripened peaches, are vastly better flavored than those artificially ripened. This is the chief reason why tomatoes grown in hothouses in the vicinity are so much superior to those shipped in from farther south. After it has come to its most perfect condition on the plant the fruit deteriorates steadily, whether gathered or allowed to remain on the vine, and the more rapidly in proportion as the air is hot and moist. That it be fresh is hardly less essential to the first quality in a tomato than it is to such things as lettuce and cucumbers.

Generally the fruit should be left on the vine no longer than will permit of its becoming fully ripe by the time it reaches its destination and is exposed for sale. When the fruit is to be shipped any distance the field should be gone over frequently, as often as every second or third day or even every day in the hight of the season, and care taken to pick every fruit as soon as it is in proper condition. When it is to be sold in nearby markets or to a cannery the exact stage of maturity, when picked, is not so important, although it is always an advantage not to gather until the fruit is well colored and before it begins to soften. Some growers for canneries make but three or four pickings, but in this case it is well to gather the ripest fruit separately.

In picking and handling great care should be taken not to mar or bruise the fruit, and the stems should be removed as the fruit is picked to prevent bruising in handling. A bruise or mar may not be as conspicuous in a tomato as in a peach, but it is quite as injurious. It is a great deal better for pickers to use light pails rather than baskets, the flexibility of the latter often resulting in bruises. It is an advantage to have enough of these so that the sorting can be from the pail, but if this is not practical the fruit should be carefully emptied on a sorting table for grading. It should first of all be separated with regard to its maturity. A single fruit which is a little riper or greener than the remainder may make the entire package unsalable. It should also be graded as to freedom from blemishes or cracks, and as to size, form and color. It is assumed that the fruit for each package is to be of the same variety, but often there is quite a variation in different fruits from even the same vine; the more uniform in all respects the fruit in a package is the more attractive and salable it becomes. There is no fruit where careful grading and packing have more influence on the price it will command.

I know of a certain noted peach-grower in northern Michigan who grew, each year, some 2 to 5 acres of tomatoes for the Chicago market. It was his custom to pick out about one-tenth of the best of the fruit, putting it into small and attractively labeled packages; the remainder of the crop was sorted over and from one-tenth to one-fifth of it rejected and fed to stock or sold to a local cannery. The remainder was sent to Chicago with his selects, but as common stock, and usually brought more than his neighbors received for unsorted fruit; but the check he received for his selects was usually as large as that for his commons, thus giving him about 33-1/3 per cent. more for his crop than his neighbors received for their equally good, but unsorted, fruit--to say nothing of what he received for the rejected fruit and the saving of freight which, he said, was usually enough to pay the actual cost of sorting.

Tomatoes are usually classed as vegetables but, when ripe, they require as careful handling as the most delicate fruits and are as easily and seriously injured by bruising and jarring. Just how this can be avoided and the fruit gotten from the vine to the possibly distant consumer in the best condition will vary in different cases. Tomatoes from the South are generally marketed in carriers which, though varying somewhat, are essentially alike and consist of an open basket or boxes of veneer holding about 10 pounds of fruit. When shipped, two, four or six of these are packed in crates made of thin boards, so as to protect the fruits but give them plenty of air.

Still another plan is to gather the green fruit and spread it not more than two to four fruits deep in hotbed frames, which are then covered with sash. Local grocers are usually glad to pay good prices for this late fruit, and in seasons of scarcity I have known canners to buy thousands of bushels so ripened at better prices than they paid for the main crop.

Adaptation of Varieties

Whatever may be their botanical origin, the modern varieties of cultivated tomatoes vary greatly in many respects, and while these differences are always of importance their relative importance differs with conditions. When the great desideratum is the largest possible yield of salable fruit at the least expenditure of labor, the qualities of the vine may be the most important ones to be considered, while in private gardens and for a critical home market and where closer attention and better cultivation can be given, they may be of far less importance than qualities of fruit.

Other varieties make a stout and vigorous but shorter growth, with more and heavier branches, shorter nodes and many small medium-sized clusters of fruit well distributed over the plant and which mature through a fairly long season. These sorts are usually very productive and our most popular varieties generally belong to this type, of which the Stone is a good representative of the more compact and the Beauty of the more open growing.

Other varieties form many short, weak, sprawling branches, with usually large and sometimes very large clusters of fruit produced chiefly near the center of the plant and which mature early and all together. Plants of this type will often mature their entire crop and die by the time those of the first type have come into full crop. The Atlantic Prize and Sparks Earliana are examples of this type.

In sharp contrast with the above is the tomato De Laye, often called Tree tomato. This originated about 1862 in a garden at Chateau de Laye, France. In this the plant rarely exceeds 18 inches in hight, is single-stemmed or with few very short branches, the nodes very short, the fruit clusters few and small. From this, by crossing with other types, there has been developed a distinct class of dwarf tomatoes which are of intermediate form and character and are well represented by the Dwarf Champion . Early maturity is sometimes the most important consideration of all, though, because of increasing facilities for shipping from the South, it is less commonly so than formerly. For shipping and canning it is generally, though not always, desirable that the crop mature as nearly together as possible, that it may be gathered with the fewest number of pickings and advantage taken of a favorable market; while for the home garden and market a longer season is desirable.

We have sorts which vary from the perfectly spherical ones of the grape and cherry, to those in which the vertical diameter is less than a third of that of the horizontal section; and the pear-shaped in which the vertical diameter is twice or thrice that of the longest horizontal section, and from those in which the outline of both the vertical and horizontal sections is smooth and flowing to those in which the vertical section has a deep indentation at both the stem and opposite ends, and those in which the horizontal section is broken by deep indentures and sutures often disposed with great irregularity.

For shipping long distances, for the rough handling, and for the easy preparation for the fruit for canning, a thick, tough skin is desirable, while for home use it is objectionable. Freedom from blemish or skin crack is also often an important quality, and we have sorts which vary greatly in these respects. The color of the skin, whether purple, red, yellow or white, is a matter of taste. In some markets the choice is given to purple fruit, like the Beauty, while in others it can only be sold at a reduced price. There are few who would care to use either yellow or white fruit for canning or cooking in any way, but many prefer them for slicing, or like to use them with the red for this purpose; we have sorts showing every gradation from white or light yellow in color through shades of red to dark purple-red, and still others which show distinct colors in splashings and shadings.

In some sorts it is large, dry, pithy and hard, extending far into the fruit even to below the center; and sometimes seems to divide into secondary or branch placentas or masses of hard cellular matter, while in other varieties it is small and so soft and juicy as scarcely to be distinguished from the flesh. Usually, but not invariably, the large and pithy placenta is correlated with large-sized fruit having many cells; where this is the case it practically necessitates the cutting away and wasting of a large proportion of the fruit in preparing it for canning, so that the canners usually prefer round, medium-sized fruits.

The character of the interior of the fruit varies greatly in different varieties. Both the exterior and divisional walls vary in thickness and in consistency. In some varieties they are comparatively thin, hard and dry; in others, thicker, softer and more juicy. In some cases there is but little interior wall, the fruit being divided into but few--even but two--cells of even size and shape, while in others there are many cells of varying size and shape. Varieties also differ greatly as to the amount, consistency and flavor of the pulp and the number of seeds. It requires from 300 to 500 pounds of ripe fruit to furnish a pound of seed of Ponderosa, while with some of the smaller, earlier sorts one can get a pound of seed from 100 to 200 pounds of fruit.

The time a tomato fruit will remain in usable condition and the amount of rough handling it will endure without becoming unsalable are most important commercial qualities depending largely upon the combined effects of the form and structure of the fruit, solidity and firmness of the flesh and ripening habit. In all these respects we have varieties which differ greatly, from the Honor Bright, which requires as much time to ripen, and when ripe is firm-fleshed and will remain usable as long as a peach, to those which 24 hours after reaching their full size are fully colored and ripe, and in 24 hours more are so over-ripe and soft that they will break open of their own weight.

These are only some of the varietal differences of the tomato. Are such differences of practical importance? I think they are, and that a wise selection of the type best suited to one's own particular conditions and requirements is one of the most essential requisites of satisfactory tomato culture. How important it seems to practical tomato growers may be illustrated by an actual case.

In a certain section of New Jersey the money-making crop is early tomatoes, and they are grown to such an extent that from an area with a radius of not exceeding 5 miles they have shipped as much as 15,000 bushels in one day, and the shipments will often average 8,000 bushels for days together. They have tried a great number of sorts, but have settled upon a certain type of a well-known variety as that best suited to their conditions and needs. Seeds of this variety which are supposed to produce plants of the exact type wanted can be bought from seedsmen for 10 cents an ounce and at much lower rates for larger quantities, but when one of the most successful growers of that locality, because of change of occupation, offered seed selected by him for his own use for sale at auction, it brought an ounce. This price was paid because of the confidence of the bidders that the seed could be depended upon to produce plants of the exact type wanted for their conditions; and I was assured that the use of this high-priced seed actually added very largely to the profits from every field in that vicinity in which it was used, but the use of some of the same lot of seed by planters in Florida resulted in financial loss because the type of plant produced was not suited to their conditions and requirements.

A wise answer can only be given after a study of each case, and no one can do this so well as the planter himself. He should know, as no one else can know, his own conditions and requirements, and should be able to form very exact ideas of just what he wants, and the doing so is, in my opinion, one of the most important requisites for satisfactory tomato growing. I also believe that it is as impossible for a man to answer offhand the question, "What is the best variety of tomato?" as for a wise physician to answer the question, "What is the best medicine?"

It is probable that a better acquaintance with sorts already in cultivation would have prevented the naming of many of these stocks as distinct varieties. What is of far more practical importance, the same name does not always stand for precisely the same type with different seedsmen, or even with the same seedsmen in different years; nor are the seedsmen's published descriptions such as would enable any one to learn from them just what type he will receive under any particular name, or which sort he should buy in order to get plants of any desired type. Seedsmen's catalogs are published and distributed gratuitously at great expense, and are issued, primarily, for the sake of selling the seeds they offer. They answer the purpose for which they are designed, in proportion as they secure orders for seeds. Will this be measured by the accuracy and completeness of their descriptions? I think that it needs but slight acquaintance with the actual results of advertising to answer in the negative, and whatever your answer may be, the answer given by the catalogs themselves is an emphatic no.

In a recent case I looked very carefully through the catalogs of 125 American seedsmen who listed a certain variety which is very markedly deficient in a certain desirable quality, and found that but 37 of the 125 mentioned the quality in connection with the variety at all and of these but 7 admitted the deficiency, while 30 told the opposite of the truth. Even if a complete, exact and reliable description of a variety was published by disinterested persons, one could not be sure of getting seed from seedsmen which would produce plants of that exact type, since there is no agreement or uniformity among them as to the exact type any varietal name shall stand for.

One way of getting seed of the exact type wanted is to do as the South Jersey growers did: go to work and breed up a stock which is uniformly of the type wanted; but this involves more painstaking care than many are willing to give, though I think not more than it would be most profitable for them to expend for the sake of getting seed just suited to their needs.

A second and easier way is to secure samples of the most promising sorts and from the most reliable sources and grow them on one's own farm; select the stock which seems best for him and buy enough of that exact stock for several years' planting, and in the meantime be looking for a still better one. Tomato seed stored in a cool, dry place will retain its vitality for from three to seven years.

Seed Breeding and Growing

The potentialities of every plant and its limitations are inherent, fixed and immutable in the seed from which it is developed and are made up of the balanced sum of the different tendencies it receives in varying degree from each of its ancestors back for an indefinite number of generations. A very slight difference in the character or the degree of any one of the tendencies which go to make up this sum may make a most material difference in the balance and so in the resulting character of the plant produced. Different plants, even of the same ancestry, vary greatly in prepotency or in the relative dominance of the influence they have over descendants raised from seed produced by them.

In some cases all the plants raised from seed produced by a certain plant will be essentially alike and closely resemble the seed-bearing plant, while seed from another plant of the same parentage will develop into plants differing from each other and seemingly more influenced by some distant ancestor or by varying combinations of such influences than of those of the plant which actually produced the seed from which they were developed. Successful seed breeding can only be accomplished by taking advantage of these principles of heredity and variation, and by a wise use of them it is possible to produce seed which can be depended upon to produce plants of any type possible to the species.

With this description in hand, search out one or more plants which seem the nearest to the ideal. In doing this it should be kept in mind that the character of the seed is determined by the plant rather than by the individual fruit. Therefore, a plant whose fruit is most uniformly of the desired type should be chosen over one having a small proportion of its fruits of very perfect type, the others being different and variable. Save seed from one or more fruits from each of the selected plants, keeping that from each fruit, or at least each plant, separate. Give it a number and make a record of how nearly, in each particular, the plant and fruit of each number come to the desired ideal. I regard the saving of each lot separately and recording its characters as very important, even when all have been selected to and come equally close to precisely the same ideal. Quite often the seed of one plant will produce plants precisely like it, while that of another, equal or superior, will produce plants of which no two are alike and none like that which produced the seed, so that often the mixing of seed from different plants of the same general type, and seemingly of equal quality, prevents the establishment of a uniform type.

The next year from 10 to 100 plants raised from each lot are set in blocks and labeled. As they develop the blocks are studied and compared with the original description of the desired type and that of each plant from which seed was saved, and the block selected in which all the plants come the nearest to the desired type, and which show the least variation. From it plants are selected in the same way and to the same type as the previous year. It is better to make selections from such a block than to take the most superior plants from all of the blocks, or from one which produced but one or but a few superlative ones, the rest being variable.

It is also well to consider the relative importance of different qualities in connection with the degree to which the different lots approach the ideal in these respects. Such a course of selection intelligently and carefully carried out will give, in from three to five years, strains of seed greatly superior and better adapted to one's own conditions than any which it is possible to purchase. A single or but a very few selections may be made each year, and the superior value of the seed of the remainder of the seed blocks for use in the field will be far more than the cost of the whole work.

Generally from 5 to 20 per cent. of the plants produced by seed as commonly grown either by the farmer himself or the seedsmen, though they may be alike in more conspicuous characteristics, will show varietal differences of such importance as to affect more or less materially the value of the plant for the conditions and the purposes for which it is grown. In a book like this it is useless to attempt to give long varietal descriptions even of the sorts commonly listed by seedsmen, since such descriptions would be more a statement of what the writer thought seed of that variety should be rather than of what one would be likely to receive under that name.

Production for Canning

A large proportion of the tomatoes grown for canning are planted under contract, by which the farmer agrees to deliver the entire yield of fruit fit for canning, which may be produced on a given area, at the contract price per bushel or ton. The canner is to judge what fruit is fit for canning and this often results in great dissatisfaction. To the grower it seems in many cases as though the quantity of acceptable fruit paid for was determined quite as much by the abundance or scarcity of the general crop as by the weight hauled to the factory. The prices paid by the factories for the past 10 years run from 10 to 25 cents a bushel, while canning tomatoes in the open market for the same period have brought from 8 to 50 cents a bushel, which, however, are exceptional prices. In all but two of the past 10 years uncontracted tomatoes could generally be sold, in most sections, for more than was paid on contract. I have given the price a bushel, though canning tomatoes are usually sold by the ton. The cost of the product of a well-equipped cannery is divided about as follows: fruit, 30 per cent.; handling, preparing and processing the fruit, 18 per cent.; cost of cans, labels, cases, etc., 43 per cent.; labeling, packing and selling, 0.035 per cent.; incidentals, 0.055 per cent.

Canning on the farm where the fruit is grown would be more generally practiced except for the popular demand that the canned product shall be brighter colored than it is possible to produce from fruit alone, and the necessary dyeing and other doctoring can be more easily and skilfully done at a central factory, though it is always at the sacrifice of flavor and healthfulness for the sake of appearance. Another advantage of canning on the farm is that it can be done with less waste of fruit. The hauling to the factory and delay in working the fruit result in a great deal of waste. The average cannery does not obtain more than 1,200 pounds of product from a ton of fruit, there being 800 pounds of waste, while with sound, ripe, perfectly fresh fruit, it is entirely practical to secure from 1,600 to 1,800 pounds of canned goods from a ton, and this saving in waste would more than counterbalance the gain from the use of the better machinery possible in the factory.

Cost of Production

There are a few vegetables or fruits where the cost of production and the price received are more variable than with the tomato. The cost per acre for raising the fruit varies with the conditions of soil, facilities for doing the work economically and with the season, while that of marketing the product varies still more. Under usual conditions, the growing of an acre of tomatoes and the gathering and marketing of the fruit will cost from to , of which from 15 to 40 per cent. is spent in fertilizing and preparing the ground, 5 to 10 per cent. for plants, 20 to 30 per cent. for cultivation, and 25 to 40 per cent. for gathering and handling the fruit. The last item, of course, varies somewhat with, but not in proportion to, the amount of the crop, as it costs proportionately less to gather a large than a small crop, and for canners' use than for market.

The expense of shipping and marketing the crop varies so greatly according to the conditions and methods that I do not attempt to state the amount. The total yield of fruit runs from 200 to 600 or 700 bushels to the acre, a 200-bushel crop of tomatoes comparing as to amount with one of 25 bushels of wheat and a 700-bushel crop of tomatoes with one of 60 bushels of wheat; with the best and wisest cultivation and under the most favorable conditions one can as reasonably hope for one as for the other. Of this total yield, from 10 to 25 per cent. of the fruit should be such as, because of earliness and quality, can be sold as extras, and there is usually from 5 to 10 per cent., and sometimes a much larger per cent., which should be rejected as unsalable. The selected fruit should net from to a bushel, the common from 30 to 75 cents--making the returns for a 200-bushel yield well sold in a nearby market to 0, and proportionately larger, for a better yield. In practice I have known of crops which gave a profit above expenses of over ,000 an acre. This came, however, from exceptionally favorable conditions and skilled marketing, and I have known of many more crops where, though the fruit was equally large and well grown, the profit was less than 0.

In this country a greenhouse is seldom used solely for the growing of tomatoes, but other crops--such as lettuce--are grown in connection with the tomatoes, so that it is impracticable to give the cost of production. As grown at the Ohio state experiment station--and the crop ripened in late spring or early summer and sold on the market of smaller cities--greenhouse tomatoes have yielded about two pounds a square foot of glass and brought an average price of 12 cents per pound. In other cases yields as high as 10 pounds a foot of glass and an average price of 40 cents a pound have been reported.

Insects Injurious to the Tomato

From the time tomato plants are set in the field until the fruit has ripened they are subject to the attacks of insects which frequently cause serious injury. On the whole, however, the tomato is not so susceptible to damage as are some related crops--such as the potato.
