Four cropping system, viz. potato-groundnut-paddy, potato-sesame (til)-paddy, potato-okra (bhindi)-paddy and patato-jute-paddy were compared at Adisaptagram Block Seed Farm, Hooghly over three years. The yields of potato were not affected by the systems. Potato-okra-paddy system was found to be most economical with highest potato yield equivalent (498 q/ha). Improvement of nutrient status of the soil (organic carbon, P and K) was also observed after three years of experimentation and maximum improvement was observed by potato-groundnut-paddy system.
