Response of Nitrogen and Plant Growth Regulators on Growth and Yield of Wheat (Triticum aestivum L.)

A research trial was conducted during Rabi season, 2022 at crop farm, Department of Agronomy Sam Higginbottom University Agriculture, Technology and Sciences, Prayagraj Uttar Pradesh India. The soil in experimental field sandy loam texture, having alkaline reaction (pH 7.7) with very low organic carbon (0.44%), available higher-level N (171.48 kg/ha), P (27.0 kg/ha) higher level K (291.2 kg/ha). To evaluate the response nitrogen different plant growth regulators on yield wheat (Triticum aestivum) experiment laid out Randomized Block Design (RBD) ten treatments each replicated thrice. treatment consists three levels (120 kg/ha, 140 kg/ha 160 combination two sprays Plant viz. [Chlormequat chloride (0.2%), Tebuconazole (0.1%) chlormequat (0.2%) + tebuconazole (0.1%)] applied 40 DAS followed 55 whose effect observed wheat. results revealed that, height (98.70 cm), recorded along (0.1%). However, maximum number tillers/running row meter (78.33), dry weight (23.01 g), rate (0.0059 g/m2/day), more effective tillers/m2 (271), highest spike length (15.10 grains/spike (60.05), test (39.75 grain (4.66 t/ha),) straw (6.98 t/ha) were -160 CCC (0.1 %) Application both improved significantly.
