Maize may be cut as soon as the centre of the grain is glazed, even if the stalks are green. There will be sufficient nutriment in the stalk to perfect the ear, and the fodder is much better than when it gets dry before it is cut. If the shocks are well put up, they may stand four or five weeks. The corn may then be knocked out, and the fodder secured for winter use.
The report of the Ohio Board of Agriculture for 1849, contains many interesting statements in reference to maize culture, made by the officers of numerous county agricultural societies. In Miami county, 2,030,670 bushels were grown, at an average yield of fifty-five bushels per acre. Three varieties are cultivated: the common gourd seed, for cattle; the yellow Kentucky, for hogs and distilling; and the white, for grinding and exportation. According to the returns from Green county, which produced 1,250,000 bushels of corn in 1849, "a regular rotation of clover, corn, wheat, and clover again, is best for corn; and no crop pays better for extra culture." The Harrison county Agricultural Society reports the pork crop at 4,800,000 pounds; and it gave its first premium for corn to Mr. S.B. Lukens, whose statement is as follows:—
"The ground had been in meadow ten years, was ploughed six inches deep about the middle of April, was harrowed twice over on the 9th May, and planted on the 11th four feet by two feet. It came up well, was cultivated and thinned when ten inches high; three stalks were left in a hill. About two weeks afterward it was again cultivated, and the suckers pulled off. About the last of June it was again cultivated, making three times the same way, as it was laid off but one way.
| d. | c. | |
| Expense of culture, gathering, and cribbing, was | 17 | 10 |
| Produce of 374⅜ bushels, at 31¼ cents | 117 | 10 |
| Profit on three acres | 100 | 00 |
The evidence on which a premium was awarded was such as should satisfy any one that 374 bushels were grown on three acres of land, and at a cost not exceeding 17 dollars 10 cents, delivered in the crib. This is producing corn at less than 5 cents a bushel.
Whether the statement be true to the letter or not, it shows conclusively the great value of a rich soil for making cheap corn. The Board of Agriculture estimates the crop of Ohio last year at 70,000,000 of bushels. Taking the United States as a whole, probably the crop of corn was never better than in the year 1849. One that has rich land needs only to plough it deep and well, plant in season, and cultivate the earth properly with a plough or cultivator, to secure the growth of a generous crop. On poor soils the case is very different.
To raise a good crop of corn on poor land, and at the least possible expense, requires some science and much skill in the art of tillage. Take the same field to operate in, and one farmer will grow 100 bushels of corn at half the cost per bushel that another will expend in labor, which is money. It unfortunately happens that very skilful farmers are few in number, in comparison with those who have failed to study and practice all attainable improvements. To produce cheap corn on poor land, one needs a clear understanding of what elements of the crop air and water will furnish, and what they cannot supply. It should be remembered that the atmosphere is precisely the same over ground which yields 100 bushels of corn per acre, that it is over that which produces only five bushels per acre. Now, the whole matter which forms the stems, leaves, roots, cobs, and seeds of corn, where the crop is 100 bushels per acre, is not part and parcel of the soil. A harvest equal to fifty bushels per acre can be obtained without consuming over ten per cent, of earth, as compared with the weight of the crop. No plant can imbibe more of the substance of the soil in which it grows, than is dissolved in water, or rendered gaseous by the decomposition of mould.
The quantity of matter dissolved, whether organic or inorganic, during the few weeks in which corn plants organise the bulk of their solids, is small. From 93 to 97 parts in 100 of the dry matter, in a mature, perfect plant, including its seeds, cob, stems, leaves, and roots, are carbon (charcoal) and the elements of water. It is not only an important, but an exceedingly instructive fact, that the most effective fertilisers known in agriculture are those that least abound in the elements of water and carbon. The unleached dry excrements of dunghill fowls and pigeons, have five times the fertilising power on all cereal plants that the dry dung of a grass-fed cow has, although the latter has five times more carbon, oxygen, and hydrogen, per 100 pounds, than the former. Although it is desirable to apply to the soil in which corn is to grow as much of organised carbon and water as one conveniently can, yet, where fertilisers have to be transported many miles; it is important to know that such of the measure as would form coal, if carefully burnt, can best be spared. The same is true of those elements in manure which form vapor or water, when the fertiliser decomposes in the ground.
Carbonic acid and nascent hydrogen evolved in rotting stable manure are truly valuable food for plants, and perform important chemical offices in the soil; but they are, nevertheless, not so indispensable to the economical production of crops, as available nitrogen, potash, silica, magnesia, sulphur, and phosphorus. These elements of plants being less abundant in nature, and quite indispensable in forming corn, cotton, and every other product of the soil, their artificial supply in guano, night soil, and other highly concentrated fertilisers, adds immensely to the harvest, through the aid of a small weight of matter. In all sections where corn is worth 30 cents and over a bushel, great benefits may be realised by the skilful manufacture and use of poudrette. This article is an inodorous compound of the most valuable constituents of human food and clothing. It is the raw material of crops.
It is not necessary to restore to a cornfield all the matter removed in the crop to maintain its fertility. A part of each seed, however, ought to be carried back and replaced in the soil, to make good its loss by the harvest.
