Abstract: In order to improve the efficiency of phosphorous fertilizer and cotton yield. The root activity and seed yield with banding phosphorus as seed manure in cotton were studied in the field. The results showed compared with farmer applying fertilizer manner, the root activity and yield increased by 1.7 times and 14.5% respectively, Agronomic efficiency of phosphate fertilizer and phosphate fertilizer partial productivity increased by 38.0% and 14.5% respectively. This study showed that banding phosphorus as seed manure not only increased the root activity and cotton yield, but also increased the efficiency of phosphorous fertilizer.
