Farmyard manure at 500 and 1000 q/ha proved to be the best level.increased in the rates of FYM, but 1000 q/ha proved to be the best level.Nitrogen at 200 kg/ha increased plant height over othere levels.The Shor dry matter production was significantly lower under contro and 50kg nitrogen at all stages of the growth as compared to 100 and 200 kg levels.The maximum yiield potential was obtained only when 1000 q/ha FYM were applied in combination with 100 kg/Nitrogen.Two hundred kg/ha nitrogen had depressing effect on tuber yields.
