An experiment was conducted in cotton growing area barind tract at Chapainawabganj during July 2021 to February 2022 for maximum benefit of cotton production with blackgram intercropping. For this experiment, a randomized complete block design with three replications were used to test the performance of six different intercroppping, including T 1 = cotton + jute, T 2 = cotton + blackgram, T 3 = cotton + spinach, T 4 = cotton + radish, T 5 = cotton + okra, and T 6 = sole cotton. The results revealed that the highest seed cotton 3134.40 kg ha -1 was produced in sole cotton growing field. Blackgram as an intercrop was given the highest gross return (354738 taka ha -1 ), net profit (214238 taka ha -1 ) and benefit cost ratio (2.52) as compared with other intercrops. Therefore, intercropping of black gram with cotton may be more economical for a good idea for farmers who grow only sole cotton in order to increase their economic return.
To observe the effect of different intercropping combinations with cotton on its growth, yield, and economic returns under rainfed conditions.
A randomized complete block design with three replications was used. Six treatments were tested: cotton + jute, cotton + blackgram, cotton + spinach, cotton + radish, cotton + okra, and sole cotton. Agronomic parameters, cotton equivalent yield, gross return, net profit, and benefit cost ratio were investigated. Data was analyzed using R-Studio statistical software with ANOVA and least significant difference tests at a 5% significance level.

The study suggests that while sole cotton maximizes seed cotton yield, intercropping with blackgram offers superior economic benefits for farmers. Blackgram's leguminous nature may contribute to soil nutrient availability, positively impacting economic returns. The findings highlight the potential of intercropping to enhance farmer income in rainfed cotton cultivation.
Sole cotton produced the highest seed cotton yield (3134.40 kg ha-1). However, intercropping cotton with blackgram resulted in the highest gross return (354738 taka ha-1), net profit (214238 taka ha-1), and benefit cost ratio (2.52) compared to other intercrops. Okra as an intercrop yielded the highest cotton equivalent yield (2743.50 kg ha-1).
Intercropping cotton with blackgram is the most economical combination, providing the best equivalent yield, economic returns, and benefit cost ratio among the tested intercrops under rainfed conditions.
- The experiment was conducted from July 2021 to February 2022. (Confirmed in abstract and methodology)
- Sole cotton produced the highest seed cotton yield of 3134.40 kg ha-1. (Confirmed in abstract and Table 1)
- Intercropping cotton with blackgram resulted in a benefit cost ratio of 2.52. (Confirmed in abstract and Table 2)
