[Illustration: Fig. 10.--White sweet-clover plant (at the left), showing the effect of a heavy growth of weeds. Had the weeds not been present the plant at the left should have been larger than the one at the right, as the seed was sown two weeks earlier and the other conditions for growth were ideal. Four-fifths of the plants on the plat which had a heavy growth of weeds were entirely killed.] When sweet clover is seeded with grain, moisture conditions should serve to determine whether the grain should be permitted to ripen or be cut for hay. When untimely droughts appear the plants may be killed if the grain is not cut as early as possible. In the South and in some sections of the Eastern and North-Central States where the soil contains an abundance of limestone and is well inoculated, a cutting of hay may usually be obtained after a grain crop has been harvested. In other sections of the North in only exceptionally favorable weather will more than pasturage be obtained after the grain is cut. TREATMENT THE SECOND SEASON. One of the special advantages of sweet clover is that it produces good pasturage somewhat earlier in the spring than most forage crops. In the North, with the exception of the extreme northern portion of the United States, it will furnish a cutting of hay in June or excellent pasturage until that time and a crop of hay or seed in late summer. In the South two cuttings of hay and a seed crop may be harvested. After maturing seed the plants die. It is a common practice in many sections to pasture the crop until about June 10, when the stock is removed and the plants are permitted to mature seed. If the plants have not been grazed closely they should be clipped at this time, so that the seed crop will ripen more evenly. Sweet clover may be pastured during the entire second season's growth, provided sufficient stock is kept on the field to prevent the growth from becoming woody. If the plants become coarse the pasture may be clipped, leaving an 8-inch stubble, so as to induce a new growth which will be more palatable. If it is desired to have the pasture reseed itself stock should be removed at least eight weeks before heavy frosts are expected, or only sufficient stock should be permitted to remain on the pasture to keep some of the plants in check.
