Studies on Pasture Mixtures : I. On the seasonal production of several grasses and legumes in pure stand : II. Effect of admixing legumes on the yield and some soil properties of pasture

[摘要] (1) Seasonal distribution of production was examined in three grasses and three legumes for two years. Total yield for two years decreased in the following order, alfalfa and Ladino clover>Italian ryegrass, red clover, orchard grass and mountain bromegrass. Orchard grass and Ladino clover indicated less variation in yearly and seasonal production than the others. (2) Yield and some soil properties of grass plot (G), legume plot (L) and grass-legume mixture (M) were investigated. Plot M produced the highest among them. Orchard grass in M plot contained higher protein content than that in G. Pasture soil can be put in the following order, L>M>G in NO3-N content, G>M>L in soil hardness and L>M>G in velocity of water infiltration into the soil.
