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. Cotton equivalent yield was higher in cotton + pigeon pea intercropping under 6:1 row ratio (1999 kg/ha) and comparable with 4:1 (1922 kg/ha) and 3:1 (1870 kg/ha). Similarly intercropping in 6:1 row ratio resulted in higher gross returns, net returns and BC ratio (Rs 89955/ha, Rs 43858 /ha and 1.95) than other row ratios and sole cotton. Higher total productivity (5.5 kg/ha/day), total profitability (Rs 120 /ha/day), Production Use Efficiency (11.1 kg/ha/day), Relative Productive Use Efficiency (33 %) and Relative Economic Efficiency (136 %) were also recorded in cotton + pigeon pea sown in the proportion of 6: 1. Total land equivalent Ratio (LER) in 6:1 sown proportion indicates that 4 % area would be required by a sole cropping system to recover the yield of inter cropping system. Total Relating Crowding Coefficient (K) values were also more than one at 6:1 and above higher row proportions (1.20 to 1.66) with maximum from pigeon pea + cotton sown at 6:1 proportion. Minimal and more or less similar partial values of cotton was observed in 3:1 to 6:1 sown proportion than other sowing proportions. The highest value of relative yield total (RYT) (1.08) and monetary advantage index (MAI ) (3602) was observed in 6:1 sown proportion.
