Effect of cultivar,row spacing and seeding rate on Alfalfa hay yield

摘要

Density of alfalfa stand required for high yield varies as the area and climatic conditions change ( Tesar and Marble, 1988; Kephart et al,1992).Little information is available on the effects of cultivar, row spacing and seeding rate on alfalfa hay yield in the western China.A field experiment was conducted in Yunmen City, Jiuquan, Gansu Province, China to evaluate the effects of cultivar, row spacing and seeding rate on alfalfa hay yield.
