Abstract: A field experiment was conducted during rabi season (2014-16) at Research Farm, R.B.S. College, Bichpuri, Agra (U.P.) to study the effect of nitrogen and FYM levels on growth, yield and uptake of nutrients in oat (Avena sativa L.) and soil fertility. The experiment was laid out in randomized block design with four levels of nitrogen (0,50,100 and 150 kg ha-1) and three levels of FYM (0, 5 and 10 t ha-1) with three replications. The results revealed that the plant height, yields of oat crop increased significantly up to 150 kg N and 10 t FYM ha-1 over control. The maximum values of green foliage (447.16 and 414,03 qha-1) and dry matter yield (64.98 and 60.30 q ha-1) were recorded with 150 kg N and 10 t FYM ha-1 , respectively. The application of FYM alone was also found to be more beneficial in terms of growth and yield of oat crop over control. The interaction effect between 150 kg N ha-1 and 10 t FYM ha-1 recorded maximum yield than other treatment combination. The maximum content (14.14 and 14.10 %) and yield of protein in oat crop (920.6 and 853.5 kg ha-1) were recorded with 150 kg N and 10 t FYM ha-1 but maximum value of crude fiber (32.96 and 33.7 %) were recorded under control, respectively. However, crude fiber content in oat was not affected significantly with N and FYM levels. The uptake of major (N,P and K) and micronutrients (Fe,Mn,Cu and Zn) by oat crop increased significantly with the levels of nitrogen up to 150 kg ha-1 and FYM 10 t ha-1, respectively. The status of organic carbon and available nutrients in post harvest soil improved with 150 kg N and 10 t FYM ha-1.The minimum amounts of available nutrients in post harvest soil were recorded under control treatment.
