=Sowing.=--The best season for sowing alfalfa will depend upon such conditions as relate to soil, moisture and climate. On rather stiff clay soils, the other conditions being right, the most satisfactory results are obtained from sowing the seed in the spring, and on land that has been plowed in the autumn and exposed to the mellowing influences of winter. But to this there may be some exceptions. On lands so light as to lift with the wind, that season should be avoided in sowing, if possible, when lifting winds prevail. Such winds are common in some localities in the spring, and may uncover the seed in some places and bury it too deeply in others. Where moisture is deficient the seed must be sown at those times when it is most plentiful. This may be in the autumn, but more commonly it is in the quite early spring. In some of the mountain States the best results have been obtained under semi-arid conditions from sowing the seed in the late autumn, so that it would be ready for germination at the first commencement of the period of growth in the spring. Under some conditions the too dry character of the weather may preclude the sowing of alfalfa in the summer and autumn months. Where moisture is plentiful all the season of growth, alfalfa may be sown almost any time, except the early spring or late autumn. Where irrigating waters are plentiful, the only hindrances to sowing alfalfa at any season of the year are such as may arise from climate. Far South in very mild areas it may be sown almost any time. Where the temperatures are low in winter, the best results are obtained from sowing alfalfa in the spring and early summer, otherwise the plants do not become sufficiently well established to withstand the rigors of the winter following. Under some conditions, sufficiently satisfactory results follow sowing in the early summer, even in Northern latitudes. Where the winters are sufficiently mild and the moisture is sufficiently plentiful, early autumn sowing, as in August or September, according to the locality, is, all things considered, the most satisfactory, for the reason, first, that it follows, or may follow, a crop grown the same season; second, that the plants are less hindered in their growth by weeds when they are young; and third, that they produce crops of soiling food or hay the first season after sowing. Many weeds do not grow in autumn and winter; hence, the less injury done by them to alfalfa plants, since the latter are so strong by spring that they overshadow the weeds in their effort to grow. When alfalfa is sown at such a time, the growth of one year virtually is gained by the process.
