Abstract: The present investigation entitled “Effect of Nitrogen levels and zinc application on yield & zinc content of direct seeded rice (Oryza sativa L.)” was conducted at the Agricultural Research Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, Uttar Pradesh, India during kharif (rainy) season of 2014 with a view to test the performance of nitrogen and zinc fertilization on growth, yield and zinc content of rice under eastern Uttar Pradesh condition to suggest better management of nitrogen and zinc fertilizer. The factorial experiment was laid out in randomized complete block design (factorial) with four levels of nitrogen viz. 0 kg N ha-1 (control), 90 kg N ha-1, 120 kg N ha-1, 150 kg N ha-1 and four types of zinc management i.e. control (Z0), 0.3% Zn as ZnSO4 spray at anthesis stage, 0.3% Zn as ZnSO4 spray at early milking stage and 0.3% Zn as ZnSO4 spray at dough stage and replicated thrice. Various observations were recorded during the course of investigation including growth attributes, yield attributes, yields, nitrogen and zinc content as affected by nitrogen and zinc fertilizer. Growth parameters were recorded at different growth stages such as 30, 60, 90 DAS and at harvest. The growth attributes included plant height, number of tillers, SPAD value, dry matter accumulation and leaf area index (except at harvest). Similarly yield attributes viz., effective tillers, panicle length (cm), panicle weight (g), number of grains per panicle and test weight, grain, straw, biological yields, and harvest index was recorded. The nutrient content such as N, P, K, Zn content and its total removal, protein content and protein yield were also noted to assess the effect of treatments. On the basis of one year field experimentation it may be concluded that independent application of 150 kg N/ha and 0.3% ZnSO4 spray at anthesis is recommended as these treatments fetched significantly higher grain yield, net returns and B:C ratio from direct seeded rice. However, application of 150 kg N/ha and 0.3% ZnSO4 spray at dough stage of crop recorded maximum zinc content. There was significant interaction effect of nitrogen and zinc for higher grain yield with N3Z1 (150 kg N/ha + 0.3% ZnSO4 spray at anthesis) and for nitrogen and zinc content in grain N3Z3 (150 kg N/ha and 0.3% ZnSO4 spray at dough stage).
