Influence of manure and nano urea on productivity and quality of wheat (Triticum aestivum L.)
Abstract
The present investigation entitled “Influence of manure and nano urea on productivity and quality of wheat (Triticum aestivum L.)” was carried out during Rabi 2022-23 at the Agronomy Research Farm, Department of Agronomy, CCS HAU, Hisar with the objectives to evaluate the effect of organic manures and nano urea on growth, quality, yield and economics of wheat. The research was carried out in factorial randomized block design with nine treatments with four replications. Factor A consisted of two wheat varieties (WH 1270 and DBW 303), assisted in main plot and while factor B comprised nine fertility levels, viz., 100% RDF, 125% RDF, 3 sprays of nano urea @ 500 ml/acre at 20-25, 40-45 and 60-65 DAS, 75% RDF + FYM @ 5 t/ha + 1 spray of nano urea @ 500 ml/acre at 40-45 DAS, 75% RDF + 2 sprays of nano urea @ 500 ml/acre at 20-25 and 40-45 DAS + PSB, 50% RDF + VC @ 4 t/ha + FYM @ 5t/ha + 1 spray of nano urea @ 500 ml/acre at 40-45 DAS, 50% RDF + VC @ 4 t/ha + 2 sprays of nano urea @ 500ml/ acre at 20-25 and 40-45 DAS, 50% RDF + FYM @ 10 t/ha + Azotobacter @ 500 g/ha, 50% RDF + 2 sprays of nano urea @ 500 ml/acre at 20-25 and 40-45 DAS + Azotobacter @ 500g/ha + PSB in sub plots. Based on the present study it was be concluded that the variety WH 1270 recorded in significantly higher growth parameters such as plant height, dry matter accumulation, crop growth rate (CGR), relative growth rate (RGR) and yield attributing characters, viz., number of spikes per mrl-1 and 1000 grain weight as compared to the variety DBW 303. Higher grain yield (5154 kg ha-1) and straw yield (6099 kg ha-1) were registered by the variety WH 1270. Among the fertility levels, maximum plant height, crop growth rate, relative growth rate along with yield attributing like number of spikes per mrl-1, number of grains per spike and 1000- grain weight were noted by the treatment with application of 125% dose of fertilizer. This treatment resulted in dry matter accumulation, number of spikes per mrl-1,number of grains per spike and 1000- grain weight at par with the treatment with 75% RDF + FYM @ 5 t/ha + 1 spray of nano urea @ 500 ml/acre at 40-45 DAS. Maximum grains yield (5426 kg ha-1) was recorded with the treatment 125% RDF which was at par with the treatments 100% RDF (5350 kg ha-1) and 75% RDF + FYM @ 5 t/ha + 1 spray of nano urea @ 500 ml/acre at 40-45 DAS (5396 kg ha-1). Maximum straw yield (5422 kg ha-1) was observed with the treatment 75% RDF + FYM @ 5 t/ha + 1 spray of nano urea @ 500 ml/acre at 40-45 DAS were applied. Highest protein content (11.26%) was recorded with the treatment where 125% RDF was applied. It was 1.3% and 1.5% higher than the treatments with 75% RDF + FYM @ 5 t/ha + 1 spray of nano urea @ 500 ml/acre at 40-45 DAS (11.50) and 100% RDF (11.48). Highest net returns (₹ 86937 ha-1) and B: C (1.24) ratio were recorded with the treatment where 75% RDF + FYM at @ 5 t/ha with 1 spray of nano urea at 40-45 DAS was applied.
