| Description |
A field study was conducted during 1987/98 and 1998/99 at the ICRISAT, Patancheru, Hyderabad, India, to evaluate the effect of landform and soil depth on water, soil and nitrate-nitrogen loss through runoff and performance of soyabean-based cropping systems. Total system's productivity (seed yield) of the soyabean+chickpea was significantly higher than the soyabean/pigeon pea intercropping system. Soyabean followed by chickpea grown on broad bed furrow (BBF) landform on medium-deep soil produced maximum yield in 1997 (2410 kg ha-1) and in 1998 (3000 kg ha-1) compared to flat land form on medium-deep soils. The seasonal runoff (287 mm, 33% of seasonal rainfall), nitrate nitrogen loss (13 kg N ha-1) and soil loss (5.35 t ha-1) from the flat landform was observed to be maximum when compared to the BBF landform. Results indicated that BBF landform on Vertic Inceptisols reduced runoff, nitrate nitrogen loss and soil loss considerably and marginally increased the yield of soyabean, pigeon pea and chickpea.
