Abstract:
An experiment was carried out during winter (rabi) seasons in 2018-19 and 2019-20 at CRC farm of sardar Vallabhbhai Patel University of Agricultural& Technology, Meerut, Uttar Pradesh to evaluate the various nutrient and weed management practices on crop growth and productivity of wheat (Triticum aestivum L.). The treatments comprised of four nutrient management options, viz., Control (No NPK) (T₁), 100% NPK (T₂), 100% NPK + Bio-stimulant-G@ 25kg/ha (soil application) (T₃) and 100% NPK + Bio-stimulant-L @ 625 ml/ha foliar spray each at 55&70 DAS(T₄) and four weed management practices weedy check (W₁), Two hand weeding (W₂), Sulfosulfuron+ Metsulfuron Methyl @ 20 + 4 g a.i. ha^-1 (W₃), Carfentrazone-ethyl + Sulfosulfuron @ 20 + 25 g a.i. ha^-1 (W4) in Factorial Randomized block design and replicated thrice. Results indicated that highest plant height, number of tillers and maximum dry matter (433.6 & 447.1, 308.7 & 318.4 and 301.7 & 305.3), and highest reduction in weed density and weed dry matter accumulation was with an application of 100% NPK + Bio-stimulant-L. Among the herbicides Sulfosulfuron + Metsulfuron Methyl @ 20 + 4 g a.i. ha^-1 gave best control of density of total weeds and dry matter accumulation at all the stages. Among the nutrient management options 100% NPK + Bio-stimulant-L @ 625 ml/ha foliar spray each at 55&70 DAS(T₄) and Sulfosulfuron+ Metsulfuron Methyl @ 20 + 4 g a.i. ha^-1 (W₃) weed management may be recommended for better growth and higher yield of the wheat crop.
