ThesisItem Embargo Effect of sowing time, nitrogen and zinc management on growth, yield and grain zinc concentration in wheat (Triticumaestivum L.).(Department of Agronomy Institute of Agricultural Sciences Banaras Hindu University Varanasi, 2022) Barik, Bandana Rani; Singh, YashwantThe present investigation entitled “Effect of sowing time, nitrogen and zinc management on growth, yield and grain zinc concentration in wheat (Triticumaestivum L.)” was conducted during the 2018-19 and 2019-20 at the Agriculture Research Farm, Banaras Hindu University. The field experiment was laid out in a split plot design assigning two sowing times and two nitrogen management in the main plot. Sowing time iscomprised of(i) D1 (Sowing in the second fortnight of November) and D2 (Sowing in the first fortnight of December) and Nitrogen management is comprised of N1(150 kg ha-1 Nitrogen [ 75 kg basal + 37.5 kg at Z20 (main shoot only) + 37.5 kg at Z37 (flag leaf visible)]) and N2(150 kg ha-1 Nitrogen [ 70 kg basal + 35.4 kg at Z20 (main shoot only) + 35.4 kg at Z37 (flag leaf visible) + 9.2 kg as 2% urea application at Z60 (beginning of anthesis stage)]).Fourzinc management in subplots are comprised ofi.e., (i) Z1(No zinc) (ii) Z2(Zinc @ 5kg ha-1), (iii) Z3(1.7 kg ha-1 Zinc as basal + 0.50% ZnSO4 spray at Z31(stem elongation) + 0.50% at Z75 (milking)), and (iv) Z4(1.7 kg ha-1 Zinc as basal + 0.50% ZnSO4 spray at Z60 (Anthesis) + 0.50% ZnSO4 spray at Z85 (Dough stage)).Significantly higher growth attributes, yield and yield attributing character, nutrient content of plant and grain after harvest, and economics of wheat(gross return, the net return, and B:C ratio) were recorded with sowing in the second fortnight of November, N2 (150 kg ha-1 Nitrogen [ 70 kg basal + 35.4 kg at Z20 (main shoot only) + 35.4 kg at Z37 (flag leaf visible) + 9.2 kg as 2% urea application at Z60 (beginning of anthesis stage)) and Z3 (1.7 kg ha-1 Zinc as basal + 0.50% ZnSO4 spray at Z31(stem elongation) + 0.50% at Z75 (milking)). While zinc concentration was more in Z4 treatment and protein content was more in D2. The nitrogen effect remained nonsignificant in most of the parameters.ThesisItem Open Access Zadoks scale based nitrogen and zinc management on yield and zinc concentration in wheat (Triticumaestivum L.).(Department of Agronomy, Institute of Agricultural Sciences, BHU. Varanasi, 2017) Barik, Bandana Rani; Prasad, Dr. S.KA field experiment was conducted during winter seasons of 2015-2016 at the Research Farm of Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, Uttar Pradesh (India) to study the effect of various nitrogen and zinc treatments on growth and yield, nutrient concentration, nutrient uptake, indices and economics. The experiment was The experiment was laid out in Randomized Complete Block Design with four types of nitrogen management viz. N1: 0 kg N ha-1 (control),N2: 120 kg N ha-1. [50% RDN at sowing+25% of RDN OF Z 20 (Crown Root Initiation stage) + at Z 41 stage (flag leaf just visible)], N3: 150 kg N ha-1. [50% of RDN at sowing+ 25% of RDN at Z 20 (CRI stage) + 25% of RDN at Z 41 stage (flag leaf just visible)] and N4: 180 kg N ha-1 [50% of RDN at sowing+ 25% of RDN at Z 20 (CRI stage) + 25% of RDN at Z 41 stage (flag leaf just visible) and four types of zinc management i.e.Z1: 0 kg Zn ha-1 (control),Z2: 2.0 kg zinc ha-1 at sowing +0.50% ZnSO4 spray at Z 30 (Panicle Initiation) + 0.50% Zn SO4 spray at Z 75 (medium milking), Z3: 2.0 kg zinc ha-1 at sowing +0.50% ZnSO4 spray at Z 52 (20% spike visible) + 0.50% Zn SO4 spray at Z 60 (anthesis) and Z4: 2.0 kg zinc ha-1 at sowing +0.50% ZnSO4 spray at Z 60 (anthesis) + 0.50% Zn SO4 spray at Z 85 (soft mid dough) replicated thrice. The result showed thatthe result also showed that the most suitable N application may be at N3 with a grain yield of 4.11 t ha-1 and Benefit: Cost ratio of 2.48 and maximum zinc content (42.10 ppm).Application of Z4would be economical for with higher grain yield of 3.73 t ha-1 and for maximum zinc content in grain(42.62 ppm).Interaction effect of nitrogen and zinc for higher grain yield and zinc content in grain with application of N3Z4and it would require some more investigation.
