Cultivation of Bt (Bacillus thuringiensis) cotton in light soils under rainfed situations is not an economically viable option and crop diversification with resource efficient and remunerative cropping systems is a sustainable agricultural practice. Under crop diversification module of IFS study, on farm studies were conducted for two years during kharif 2015 and kharif 2016 in 21 farmer’s fields in three villages to evaluate the introduction and performance of mid early duration pigeon pea (WRGE 97) under cotton + pigeon pea intercropping in different sowing proportions like 3:1, 4:1, 6:1, 8:1 and 10:1 in comparison with sole crops of pigeon pea and cotton. | Yield, economics and cropping indices of cotton + pigeon pea inter cropping under varying row ratios in rained conditions
