The present study is a part of long-term fertility experiment carried out since 1984 and was conducted at A2 block of N. E. Borlaug Crop Research Centre of G.B. Pant University of Agriculture and Technology, Pantnagar (Uttarakhand) during kharif 2017. Nine treatments out of fourteen consisting different combination of N, P, K, Znf and FYM were tested in a Randomized Block Design with four replications. The variety sown was HKR 47. In this study nitrogen, phosphorus and potassium content in rice grain and straw; uptake of nitrogen, phosphorus and potassium by rice grain and straw; and total uptake was evaluated. Results revealed that different treatments had significant effect on nutrient content and uptake in rice. Treatment with recommended dose of fertilizer to rice, N120P40K40 + Znf, gave higher values of all, nitrogen, phosphorus and potassium content and uptake, over other treatments with only inorganic fertilizer application. But FYM application along with NPK and NPK +Zn enhanced concentration of nutrients as well as their uptake and that increased significantly with the application of N, P, K Zn and FYM applied in balanced combination. The highest values of nitrogen, phosphorus and potassium content uptake in rice were obtained under N120P40K40 + Znf + FYMr and N120P40K40 + FYMr treatments. Higher values of nutrient content and uptake directly relates to better productivity of crop, thus the higher values of nutrient content and uptake in FYM applied treatments in comparison to other treatments showed its importance indirectly in producing better yield by rice crop.
