Effect of NPK and Growth Regulators on Growth and Productivity of Wheat (Triticum aestivum L.)

Abstract

The present study highlights the effect of NPK and growth regulators on growth and productivity of wheat (Triticum aestivum L.). Wheat is one of the most important and widely grown food crops with over 25000 different cultivars. The exploration was carried out during Rabi season 2021-22 at Instructional farm, BTC College of Agriculture and Research station, Bilaspur (C.G.). The soil of the experimental site was clayed in texture. The wheat (Var. HI-1544) was grown and treatments were replicated three times in randomized block design. The experiment consists of twelve treatments The crop was sown on 11 November, 2021 and harvesting was done on 24 March 2021.The result that higher grain (45.55 q ha-1) and straw (46.45 q ha-1) yield were observed under the treatment 150% RDF + Two spray of growth regulator at first node(35 DAS) & boot leaf stage (60 DAS) (T9). The improvement in yield of wheat was recorded with the application of 150% RDF + Two spray of growth regulator at first node(35 DAS) & boot leaf stage (60 DAS) (T9) which was at par with the application of 150% RDF (T6). Treatment (T9) assigned yield advantage of 21.19% and 21.52% in grain and straw yield respectively as compared to 150% RDF (T6) and Absolute control (T1). The result of the present study came to the conclusion that the application of 150% RDF+ growth regulators through fertilizer is essential to get higher production output and profit from wheat cultivation and reduce the risk.
