The experiment comprised of two cotton genotypes, two sowing time of cotton, four cropping systems and six sole crops. In all there were 22 treatments including sole crops. The experiment was laid out in a Factorial RBD design with three replications. Across cotton sowing time and cropping systems, hirsutum genotype Abhadita recorded 7.4 per cent higher kapas yield over herhaceum genotype Jayadhar. Regardless of cotton genotypes and cropping systems, cotton sown early during July second fortnight recorded 32.2 per cent higher kapas yield over cotton sown late during August second fortnight. Irrespective of row proportions, intercropping of Soybean in Chilli+Cotton mixed cropping system resulted in a significant reduction of both Chilli and Cotton yield. The reduction in Chilli yield was 6.8, 44.5 and 10.7 per cent whereas, reduction in kapas yield was 8.3, 34.7 and 10.5 per cent with 1:1, 1:2 and 2:2 row proportions respectively. However reduction in chilli and cotton yield in intercropping system was better compensated by intercrop yield of soybean as seen in equivalent yield and monetary returns. Intercropping one row of soybean with chilli and early sown Abhadita cotton (G2T1C1) recorded significantly higher chilli equivalent yield (1508 kg ha-1) over chilli mixed with early planted Abhadita (1168 kg ha-1) or Jayadhar (1051 kg ha-1) cotton alone. Similarly, G2T]C] gave higher net returns (Rs. 33812 ha-1) compared to chilli mixed with early planted Abhadita (Rs. 24937 ha-1) or Jaydahar (Rs. 22306 ha-1) cotton. Among sole crops, chilli recorded significantly higher net returns (Rs. 19144 ha-1) compared to soybean (Rs. 17449 ha-1) and early sown Abhadita cotton (Rs. 11870 ha-1)."ennullThesis
