Nutrient uptake in multicut fodder sorghum under sole and intercropping situations with different nitrogen levels

Field experiments were conducted at Agricultural College and Research Institute, Coimbatore during rabi 2004 and summer 2005 to study the influence of intercropping of cowpea and nitrogen levels on nutrient uptake of multicut fodder sorghum. Harasona extracted higher amount of nutrients than other varieties of fodder sorghum. Intercropping of fodder cowpea in sorghum did not affect the nutrient uptake of ratoon crops significantly than application of 30 kg N/ha after each cutting but it was comparable with application of 45 kg N/ha after each cutting.
