Abstract

This study aimed at discussing the effects of fertilizer classes and quantities on yield and growth development in cotton.The results showed that: Applied 16∶16∶18 compound fertilizer 450 kg/hm~2 before seeding and 24∶10∶6 compound fertilizer 150 kg/hm~2 during the bud and boll period,the yield of seed cotton,fertilizer efficiency and the value cost ratio were higher than the others.The yield of seed cotton yield was(4 038.0 kg/hm~2),fertilizer use efficiency and the value cost ratio were respectively 252.5 kg/(kg·hm~2) and(24.54∶1).The formula was optimum.
