When sown in combinations such as have been named above, it will be necessary to modify somewhat the amounts of alfalfa seed sown, according to the proportion of the other seeds sown with the alfalfa. But since many grasses are more aggressive than alfalfa, it is not necessary to reduce the amount of alfalfa seed sown proportionately to the amounts of the other seeds that may be sown along with it. In many instances it may be proper not to reduce the amount of the alfalfa seed at all, as some of these grasses will soon crowd the alfalfa plants, to their injury, even though the usual amount of seed should be sown. The amount of the grasses sown with the alfalfa will, of course, vary. It will seldom be necessary in any instance to sow more than 6 or 7 pounds per acre, and under many conditions not more than 5 pounds. When alfalfa is sown with timothy and clover in temporary meadows or pastures, it is seldom necessary to sow more than 3 to 5 pounds per acre, and the same is true of it when sown in a permanent pasture. The crop is so little grown for hay in mixtures, that it is scarcely necessary to dwell upon the nature of these, or the respective amounts of seed to sow in making them. When alfalfa is sown with the grain, there will be a saving of seed to the extent of at least 20 per cent., as compared with broadcast sowing. This arises from the more general sprouting of all the seeds, since they are planted at a more uniform depth, and from the subsequent loss of a smaller percentage of the plants through drought, and it may be other causes. But when sowing broadcast, it will in many instances prove more satisfactory to add 20 per cent. to the amounts mentioned above, as suitable for being sown without admixture with other grasses and clovers, rather than to deduct 20 per cent. from these amounts when sowing the seed with the drill.
