Abstract :
The study was laidout during Rabi season of 1994-95 and 1995-96 at Student’s instructional Farm, C.S. Azad university of Agriculture and technology, Kanpur. The soil of experimental field was sandy loam, having low fertility status. Five cropping systems i.e., Indian mustard sole, Indian mustard + lentil, Indian mustard without lentil at same distance, Indian mustard + French bean and Indian mustard without French bean at same distance were tested under three levels of phosphorus (control, 30 kg P2O5/ha and 60 kg P2O5/ha). the highest yield of Indian mustard by 24.04 q/ha was harvested under treatment of Indian mustard sole. In associated cropping system of lentil and French bean, Indian mustard yielded by 11.72 q/ha and 15.00 q/ha seed yield, respectively. The yield of Indian mustard was obtained 16.95 q/ha at 30 kg P2O5/ha closely followed by 60 kg P2O5/ha (16.45 q/ha). the growth and yield traits of Indian mustard were concordant to the yields obtained from Indian mustard under different cropping systems and levels of phosphorus. The yield of intercropped lentil and French bean were harvested by 6.69 q/ha and 12.02 q/ha, respectively. Both inter crops provided more granin yield upto highest tested dose of 60 kg P2O5/ha closely followed by 30 kg P2O5/ha. The growth and yield fruits of both crops were commensurable to the yields obtained from lentil and French bean under cropping systems with Indian mustard and levels of phosphorus application.
