Effect of Integrated Nutrient Management on Nutrient Uptake and Yield of Cowpea in Southern Dry Zone Soils of Karnataka

摘要

A field experiment was conducted on Integrated Nutrient Management to study the nutrient uptake and yield attributes and yield of cowpea in Southern Dry Zone of Karnataka at Shambhunahalli village, Mandya taluk and district. A Complete Randomised Block Design was used with eleven treatments and three replications. The results indicated that application of 100 per cent RDF+FYM significantly increased the uptake of major nutrients, N, P and K (39.5,20.36,41.90 kg ha~(-1) respectively) followed by 75 per cent RDF+FYM. Application of 100 per cent RDF+FYM significantly increased the pod length (15.85), seed yield 1586 kg ha~(-1), stover yield 5124 kg ha~(-1), harvest index (0.23) and significantly higher net returns of Rs. 22,372 ha~(-1). Higher B:C ratio was recorded in 100 per cent RDF+FYM followed by 75 per cent RDF+FYM.
