Effect of split application of potassium on yield and yield components of summer groundnut in acid terai soil of north Bengal



Effect of split application of potassium on yield and yield components of summer groundnut in acid terai soil of north Bengal



Journal of Potassium Research 10(1): 73-77



In field experiments at Coochbehar, West Bengal, in the 1990-91 summer seasons, irrigated groundnuts AK 12-24 were given 30, 50, 70 or 90 kg K2O/ha basally or in 2 splits (basal and 40 d after sowing). Pod yields, yield components and oil yield were increased by K compared with no-fertilizer controls. At higher K rates (70 and 90 kg K2O/ha) split application was better than applying all the K at sowing, whereas at lower K rates basal application gave the higher yields.
