Experiments on rice-wheat/chickpea cropping sequence for sustaining production and productivity of soli were carried out during 1994–95 and 1995–96 using Sesbania rostrata as green manure alongwith phosphomicrobe and phosphate carriers at different levels of N at Crop Research Station, Pura, Kanpur. Significantly higher increases In the production of rice were obtained as a result of the use of these inputs irrespective of N levels. The yields obtained with 60 kg N + green manure + 60 kg P2O5 (SS) + phosphomicrobe was at par with 120 kg N + 60 kg P2O5 + 60 kg K2O ha−1. Uptake of nutrients (NPK) almost followed the trends similar to increase in yields. There were considerable improvements in the physical properties of soil viz. water holding capacity and bulk density. Carry-over effect of these inputs after rice influenced the yields of wheat and chickpea likewise.
