fifth year with the Southern Field Pea, or other green crop, and marl, he will have land that will continue to produce paying crops of the brightest and most salable peanuts. There is an abundance of good peanut land all along the Atlantic seaboard, from New Jersey to Florida. Doubtless there is much of it in the Mississippi Valley, even as far north as the lake region, and on the Pacific coast from Oregon southward. There is no more reason for confining the cultivation of the Peanut to the narrow belts at present occupied, than there is for limiting tobacco to the States of North Carolina and Virginia.
The quantity of lime or marl to use at one application depends very much on the nature of the soil and the amount of vegetable matter it contains. Generally, fifty bushels of lime, or one hundred and fifty bushels of marl is a safe application, but if the soil is quite thin, and contains but little vegetable mould, more than this at one time would be attended with risk. The safer plan is, to make several small annual applications of both marl, and vegetable matter, continuing this until a hundred and fifty bushels of lime, or two hundred and fifty, or three hundred bushels of marl have been applied. After this, no more calcareous matter will be needed in fifteen or twenty years. Land will bear large quantities of marl with perfect safety, if kept well stocked with some vegetable matter to subdue its caustic effects. But as most of the best peanut soil is deficient in this respect, the planter should begin cautiously, using small quantities until he has deepened his soil and supplied it with vegetable mould by trashing the land or turning in green crops.
In choosing land for a peanut crop, some attention should be paid to the previous crop. The Peanut requires a clean soil, one clear of roots, brush, stones, or rubbish of any kind, and hence it should follow some hoed crop, such as corn, cotton, or tobacco. In Virginia, corn land is generally preferred, and, as in the tide-water section, much of this land has been heavily marled, it commonly produces well.
The preparation of the soil for the Peanut is the same as for corn, or any similar crop, except that more pains should be, and generally are taken, to get it in fine and mellow tilth. If it breaks up rough and turfy, as much land previously in corn is apt to do, it should be harrowed or dragged until it is fine. Generally, Virginia planters do not plow quite so deep for peanuts as they do for corn. This practice the writer believes to be unsound. Land should be plowed deep at the outset for all crops, whatever their nature or manner of growth. Deep plowing is a corrective of dry weather, and as drouth sometimes tells heavily on the Peanut plant, as was the case in the season of 1883, it is always well to plow deep, and give the moisture of the subsoil a chance to rise upward, and reach the roots during a dry spell. The formation of a fine, mellow seed bed, is all the preparation a peanut soil requires, previous to planting time, apart from the application of manures, which is spoken of elsewhere.
The Seed.—With the peanut crop, more than with almost any other, good seed is a matter of paramount importance. The seed sometimes fails to germinate well; before this fact can be discovered, and the ground re-seeded, unless the first planting was made quite early, the best season for planting will have passed, and the crop planted late will never be so good as it might have been. On the other hand, a very early planting doubles the risk of failure, in fact almost challenges failure by committing the seed to a soil too cold for germination and a quick growth. It is highly important, then, to have good seed, and to wait until both weather and soil are favorable for speedy germination and growth.
In order to determine whether the seed will germinate well or not, let the planter begin to test them early in the spring. Let him take a dozen or two kernels that appear to be in quality a fair average of the whole lot of seed on hand, place them in a tumbler with some dampened cotton, or a piece of sponge, and set the tumbler in a warm place, where the heat is uniform, and high enough to start the germ in a few days. In a day or two, if the seeds are good, they will begin to swell, and the embryo plant will soon begin to grow. Thus, according to the number of seeds that have germinated out of the number tested, the planter can calculate the probable per-centage of good seed. A glass of peanuts growing thus in dampened cotton, presents an interesting study, and is a pretty ornament for the sitting room.
But the planter must not rest satisfied with one trial. As soon as the out-of-door temperature will admit of it, he should try quite a number of the seeds in the open ground. Selecting a warm, sunny spot, he should plant from fifty to one hundred kernels, and shelter the place as much as possible from the cold winds. If these germinate well, the seed may be relied upon as good, and no further trial need be made. It is in this way that the Virginia planter tests his seed every season. About the first of April there is a great testing of the seed peanuts, and, although nearly every planter endeavors to save his own seed, the quantity of doubtful seed is generally great enough to cause a brisk demand for good seed at advanced prices. The method of saving seed peanuts will be given in a subsequent chapter.
Some weeks before planting time, the Virginia farmer, who plants from fifty to a hundred bushels of peanuts, starts about having them shelled and assorted, preparatory to planting. This must be done with care, and females are mostly employed to perform this work. The pods are popped open with the fingers and thumb, care being taken not to split or bruise the kernel; all shrivelled and dark colored kernels are rejected. After they are shelled, the seed must be put into bags or baskets, a small quantity in each parcel, and set where there is a free circulation of air, until wanted for planting. If a large quantity is bulked together after being shelled, or if put in a close box or barrel, even in small quantities, they are liable to heat, and be prevented from germinating. This fact is the result of some costly experience on the part of many planters. Thus it becomes necessary to handle the seed with great care and circumspection throughout. From a bushel to a bushel and a half of peanuts in the hull, or pod, is estimated to be enough to plant one acre of ground, the quantity depending on the quality of the seed and the distance apart they are to be planted.
Time of Planting.—In Virginia, the first twenty days in May is regarded as, in the main, the most suitable time for planting. Some plant as early as the last week in April, and the seasons frequently favor this early start, and the crop does well. More, however, plant in June than in April, and sometimes planting is delayed until the middle or last of June. On warm and dry land, there is no great risk in planting the first week in May, but on colder land, the planter should wait until the ground has been warmed by the sun, say the latter part of the same month. If the farmer has reason to hope for a week or ten days of mild, fair weather, he may risk a planting quite early, as in that time the seed ought to germinate, and come up sufficiently to make it sure that it will grow. Once up, the plant will hold its own, and though cold rains or winds may retard its growth, and cause it to turn yellow, it will start anew with the first spell of sunny weather, and rapidly change color to its normal green. The above dates apply to the latitude of Virginia. In the far south, peanut planting begins early in April, while north of Virginia, the first half of June would, in most seasons, be quite
