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

The present experimental study was carried out during Rabi season 2020-21 at Instructional farm, BTC College of Agriculture and Research station, Bilaspur (C.G.). The soil of the experimental field was clay in texture. The wheat Var. HI-1544 was grown and treatments were replicated three times in randomized block design. The experiment consists of nine treatments The crop was sown on 11th November, 2020 and harvesting was done on 24th March, 2021.The result revealed that maximum yield parameters the significantly higher grain (45.55 q ha1) and straw (46.45 q ha-1) yields were observed under the treatment 150 % RDF NPK + Two spray of growth regulator at first node (35 DAS) and boot leaf stage (60 DAS) (T9). Further, among the nutrient management treatment, significantly maximum grain and straw yield up to (43.65q ha-1) and (46.35q ha-1) respectively were recorded under150 % RDF NPK (T6). However, the treatment (T9) was statically similar with the treatment (T6). The improvement in yield attributes and yield of wheat was recorded with the application of 150 % RDF NPK + Two spray of growth regulator at first node (35 DAS) and boot leaf stage (60 DAS) (T9) which was at par with the application of 150 % RDF NPK (T6). Treatment (T9) assigned yield advantage of 21.19 % and 21.52 % in grain and straw yield respectively as compared to 150 % RDF NPK (T6).
