Performance of American cotton-legumes based intercropping system on nutrient uptake and soil nutrient status

The field experiment was conducted during kharif season of 2014–15. The experiment was laid out in randomized block design, replicated thrice with eleven cropping systems. Significantly highest NPK uptake (38.97, 13.39 and 34.85 kg ha⁻¹ respectively) was recorded in the cropping system of sole cotton. Significantly highest available N (222.75 kg ha⁻¹) was recorded in sole blackgram and maximum available P (21.52 kg ha⁻¹) was recorded in cotton + cowpea intercropping system. Cotton + clusterbean intercropping system was recorded significantly highest available K (355.60 kg/h)
