Influence of Integration of Inorganic Nutrient Sources with Organic Manures on Growth and Yield Attributes of Wheat (Triticum aestivum L.)

Abstract— A field study was conducted during rabi season 2022-23 and 2023-24 at the Department of Agriculture, Sri Guru Granth Sahib World University, Fatehgarh Sahib on Influence of Integration of inorganic nutrient sources with organic manures on growth and yield of Wheat (Triticum aestivum L.). The experiment was laid out in Randomized Block Design in three replications with 14 treatments. The values for growth attributes such as plant height (81.66 cm), leaf area (6.14 m2), dry matter per meter row length (302.48 g) and no. of tillers per meter row length (124.33) were recorded maximum under T9 (100 % RDN through chemical fertilizer + 25% RDN through poultry manure) for both years. This was statistically at par with treatment T2 (100 % RDF (125 kg ha-1)), T5 (100 % RDN through chemical fertilizer + 25% RDN through FYM) and T7 (75 % RDN through chemical fertilizer + 25% RDN through poultry manure). On the contrast, the lowest values were observed under treatment T1 (control) for growth attributes. Similarly, the yield attributing characters viz., no. of spikes, spike length, total no. of grains and 1000 grain weight were maximum under T9 and also at par with treatment T2 and T7. The lowest values were observed under treatment T1 (no nutrient source) for given parameters. This study revealed that integration of organic nutrient sources with inorganic sources showed better results for mentioned growth and yield attributes of wheat crop.
