IMPORTANCE OF SIMILAR CONDITIONS
The farmer who has brought himself to the point of introducing alfalfa upon his farm should be extremely careful in the selection of seed. In the first place it is important that he should sow such as is produced in about the same latitude as his farm and from a region of about the same rainfall, thus keeping in a line of acclimation, and with the habits and habitat, as it were, of what he is seeking to raise. Next, he should not sow seed raised under irrigation if he is in a non-irrigation region. A Michigan farmer, for example, should sow seed grown as near to his latitude as possible, say, from Wisconsin, Minnesota or the Dakotas, or not south of Nebraska or Kansas. It is questionable, at present, whether it is wise or profitable to attempt raising alfalfa seed in the more humid districts of the eastern and southern parts of the United States. It may be economy to leave the raising of seed to those regions with the least summer rainfall, keeping always in mind the securing of seed grown under conditions nearly like those to which the seed is to be introduced.
Speaking of the alleged different varieties of alfalfa, the seed of which is urged upon buyers by seedsmen, the editor of the Oklahoma Farm Journal pertinently says:
“We see occasional references to ‘dry land’ alfalfa and statements that it’s a kind that just longs for the hilltops so that it may turn off big crops of rich hay from land too dry and hard to yield good sorghum. Don’t forget that the one thing to look for when purchasing alfalfa seed is good seed, that will grow. It’s hard to find and the price is usually high. When you buy it, buy subject to test and send a fair sample of about an ounce to your experiment station, where it will be tested without charge. At the present time there is but one variety of alfalfa that Oklahoma farmers should buy, and that is good alfalfa seed. There is no ‘dry land’ variety of alfalfa, and the much boomed Turkestan variety isn’t as good for sowing in Oklahoma as Oklahoma or Kansas grown seed. Rich soil, thorough preparation, good seed well sowed, cutting at the right time, harrowing when weeds and grass bother, all these are requisite to success with this most valuable crop, and it pays for all the bother.”
Seed from Nebraska and northwestern Kansas has been generally successful through Iowa and Illinois, and is probably adapted to Ohio and southern Pennsylvania. Utah seed produces good crops in Minnesota, the extremes of cold and heat in Utah having developed a strain that does well in cold climates. The writer would use Utah grown seed for New York, northern New Jersey and northern Pennsylvania, and seed from Wyoming or Montana for New England. On the sandy land of southern New Jersey, in Delaware and Maryland, the seed grown in southern Colorado and southern Kansas ought to do well.
Prof. H. M. Cottrell, formerly agriculturist of the Kansas experiment station, says: “One year I sowed 20 acres to alfalfa—19 acres with Utah grown seed and one acre with imported seed; both showed a germination of over 98 per cent, and the growth was good from both lots all through the season, with no difference that could be detected. The next spring there was a good stand all over the 19 acres seeded with Utah seed, and not a single live plant on the acre seeded with the imported seed. I have seen several trials with imported seed, and never yet saw a good crop harvested from it. Usually after passing through the first winter there is from one-fourth to one-half a stand from such seed; the plants make a weak growth and, if allowed to remain, most of them die out in two or three years. Descriptions of the puny growth in reports of failures of this crop, given by eastern growers, make one think that probably imported seed had been sown. No intelligent farmer would take corn grown in the warm soil and climate and long season of southern Kansas and expect to grow a good crop in New York on heavy soil with short seasons. It is even more difficult to succeed with so great a change in growing alfalfa, as it would have to withstand the long severe winter, as well as the change in summer conditions. No one should sow alfalfa seed without knowing where and under what conditions it was grown.”
New seed, other conditions being right, is always preferable, although that kept for several years, properly cared for, may have retained most of its germinability. Such tests as have been made appeared to show a loss in well stored seed of only about one and one-half per cent of germinability in five years. W. P. Headden (Colorado Bul. No. 35) after various experiments declares, “the results are positive in showing that the age of seed up to six years does not affect its germinating power.” It is usually handled and stored by seedsmen in the ordinary seamless cotton sacks holding from 150 to 160 pounds, and quoted and sold by the pound or hundred-pounds instead of by the bushel. The legal weight of a bushel of recleaned alfalfa seed is sixty pounds.
Although the seed is handled in sacks for convenience, seedsmen say there is no good reason why it might not be safely stored in bulk in bins without any deterioration from heating, or otherwise. There might, however, be some degree of danger from weevils or other insect pests in warm weather. Exposed to too much light, seed will lose its bright yellow color and change to a brownish cast. When stored, dealers say, it does not go through a “sweating” process as do the seeds of some other forage plants and grasses.
