Abstract: Field experiments were conducted at farmer’s field, Chinnakottakuppam village, Tamilnadu to study the effect of integrated nutrient management on the productivity of groundnut (kharif)-groundnut (rabi) cropping systems. The results indicated that incorporation of pressmud compost significantly improved the productivity of groundnut-groundnut cropping system. Similarly, application of 100% recommended N and P recorded better growth, yield attribute and yield of kharif groundnut whereas, application of 100 and 75 per cent recommended N and P to the kharif groundnut resulted in higher growth, yield contributing character and pod yield of succeeding rabi groundnut. Regarding biofertilizers treatments, inoculation of biofertilizers had positively influenced the growth and yield of groundnut-groundnut cropping system.
