Abstract: The present investigation entitled “Effect of nitrogen and zinc fertilization on yield and zinc content in wheat (Triticum aestivum L.)” was conducted at the Agricultural Research Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, Uttar Pradesh, India during winter season of 2012-13 with a view to test the comparative performance of nitrogen and zinc fertilization on growth, yield and zinc content of wheat under eastern Uttar Pradesh condition to suggest better management of nitrogen and zinc fertilizer. The experiment was laid out in Randomized Complete Block Design with four types of nitrogen management viz. 0 kg N ha-1 (control), 50% RDN at sowing + 50% RDN at Z 20 (CRI stage), 50% RDN at sowing + 25% RDN at Z 20 (CRI stage) + 25% RDN at Z 30 (pseudo stem erection) and 50% RDN at sowing + 25% RDN at Z 20 (CRI stage) + 25% RDN at Z 37 (flag leaf just visible) and four types of zinc management i.e.0 kg Zn ha-1 (control), 0.5% Zn spray at Z 45 (booting), 0.25% Zn spray at Z 45 (booting) + 0.25% Zn spray at Z 60 (anthesis) and 0.25% Zn spray at Z 45 (booting) + 0.25% Zn spray at Z 73 (milking) 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 managements. Growth parameters were recorded at various phenological stages at 30 DAS followed by 60, 90 DAS and at harvest which included plant height, number of tillers plant-1, SPAD value, dry matter production m-2 and leaf area index. Similarly yield attributes viz., ear length, number of ears m-2, number of grains ear-1 and 1000 grains weight; grain and straw yield and total uptake of the nutrients (NPZn) were also noted to assess the effect of treatments. On the basis of experimental findings, the following broad conclusions can be drawn: The most suitable N application may be 50% RDN at sowing + 50% RDN at Z 20 (CRI stage) with a grain yield of 3518.17 kg ha-1 and B: C ratio of 2.17 but for maximum zinc content (39.97ppm) most suitable may be 50% RDN at sowing + 25% RDN at Z 20 (CRI stage) + 25% RDN at Z 37 (flag leaf just visible).
