IPNI-1995-CHN-AH8

Maximum yield research on cotton in Anhui, 1996 Average yields of cotton in Anhui province remain low (582 kg/ha) due to unbalanced fertilization. MYR data indicate P and K fertilizer rates of 90 and 225 kg/ha would be necessary for efficient cotton production. Currently, the province is a major center of cotton production with annual plantings of 443,000 ha. This information will be included in a national extension program focused on cotton nutrition.

1995

Maximum yield research on cotton in Anhui, 1995 Decreasing cotton production is threatening Anhui's textile industry. A major reason for lower production is low rates of unbalanced fertilizer nutrient application to this nutrient demanding crop. The highest rates of fertilizer application, 300-90-270 kg/ha N-P2O5-K2O produced 1,517 kg cotton/ha. Yields were 14 percent higher compared to the no potash treatment and 6 percent more compared to the 60 kg P2O5/ha treatment.
