Abstract: The present exploration entitled “Effect of nutrient management and plant growth regulators on growth and yield of Wheat(Triticum aestivum L.)” was carried out during Rabi season 2022-23 at Instructional farm, DKS College of Agriculture and Research station, Bhatapara (C.G.). The soil of the experimental site was clays in texture. The was laid out in randomized block design with three replications. Various growth parameters were measured at different stages of the wheat crop, and the results were analyzed. The results demonstrated a significant impact of nutrient management and PGR on various growth parameters of wheat. At 30, 60, 90 days after sowing, and at harvest, treatment T10 (75% RDF + Chlormequat chloride (Lihocin) @ 0.2 % + Tebuconazole @ 0.1% at first node (35 DAS) & boot leaf stage (60 DAS) consistently exhibited the significant reduction in plant height. It also resulted in the maximum number of leaves and tillers at 30, 60, 90 days after sowing, and at harvest.treatment T10(75% RDF + Chlormequat chloride (Lihocin) @ 0.2 % + Tebuconazole @ 0.1% at first node (35 DAS) & boot leaf stage (60 DAS) showed the highest grain yield and straw yield at harvest, indicating its positive influence on the yield of wheat. The study also examined the dry matter accumulation, crop growth rate, relative growth rate, leaf area index, harvest index.Treatment T10(75% RDF + Chlormequat chloride (Lihocin) @ 0.2 % + Tebuconazole @ 0.1% at first node (35 DAS) & boot leaf stage (60 DAS) consistently showed the maximum values for these parameters at different stages of growth, suggesting its potential in enhancing wheat productivity followed by T9(75% RDF + Chlormequat chloride (Lihocin) @ 0.2 % + Tebuconazole @ 0.1% at first node (35 DAS) & boot leaf stage (60 DAS).
