Background: Horizontal expansion of area under pulses at country level has very little possibilities. This necessitates exploring
alternate ways to increase the area and production of pulses. Bt cotton is the major cash crop grown in large area in Southern
transition zone of Karnataka on red soils. Bt cotton hybrids are sown at wide row spacing hence provide sufficient space for cultivation
of short duration pulses like cowpea and horse gram.
Methods: On-farm trials were carried out in medium deep red soils of Basavanagiri village of Mysore district, Karnataka during 2014-
15 and 2015-16. There were six treatments consists of Bt cotton with farmers practice (T1), Bt cotton with best management practice
(T2), sole cowpea (T3), sole horse gram (T4), Bt cotton intercropped with cowpea (T5) and Bt cotton inter cropped with horse gram
(T6). On-farm trials were laid out by using RCBD design in five farmer fields, which served as replications.
Result: On-farm investigation indicated that there was no much difference between cotton yield sole crop with BMP and inter cropped
cotton yield. However, cotton yield was significantly lower in farmers practice over BMP. Intercropping of cowpea and horse gram with
Bt cotton resulted in higher cotton equivalent yield, LER and production efficiency over the sole cotton cropping system. This was due
to the wider spacing of the cotton and better resource use efficiency in intercropping system.
