Abstract

An experiment was conducted at a farmer's field on Alfisol to study the effect of different fertilizer recommendation practices on changes in organic carbon, available N, P and K status of the soil and yield of groundnut and finger millet. The highest yield of groundnut and finger millet was obtained when fertilizers were applied as per the package of practices of University of Agricultural Sciences, Bangalore where 100% recommended NPK fertilizers along with 7.5 t FYM ha−1 was applied. The organic carbon, available N, P and K content of soil were significantly improved with the use of 100% recommended fertilizer + 7.5 t FYM ha−1 in groundnut-finger millet cropping system.
