Adequate potash and other fertilizers for high yield banana in Hainan province

IPNI-1995-CHN-HI22

Adequate potash and other fertilizers for high yield banana in Hainan province, 1996 Application of 1,200 kg K2O/ha to banana resulted in 83. 6 percent yield increase in Hainan province. Despite higher rates, the local 15-15-15 N-P2O5-K2O compound fertilizer applied at 1,200 kg/ha resulted in 3 percent lower yields than a balanced N, P and K treatment. In addition to the yield advantage, proper fertilization resulted in banana maturing faster compared to local farmer practices. Read more
