Assessment of weed management and nutrient management performance on wheat productivity under sub humid-climatic condition

Abstract

A field experiment was conducted at research farm, Department of Agronomy, Faculty of Agriculture and Veterinary Sciences, Mewar University Gangrar, Chittorgarh (Rajasthan) during Rabi season of 2024-25 to to evaluate the combined effects of Integrated Weed Management (IWM) and Integrated Nutrient Management (INM) on growth, yield attributes, and yield of wheat. The results revealed that the combined application of 100% Recommended Dose of Fertilizers (RDF) with Clodinafop + Metsulfuron (T₅) significantly improved plant population (51.68 plants/m row), plant height (93.45 cm at harvest), spike length (11.25 cm), grains per spike (36.45), grain yield (42.32 q/ha), and straw yield (56.60 q/ha), which were at par with T₄ (RDF + Sulfosulfuron + Metsulfuron) and T₆ (RDF + Sulfosulfuron + Carfentrazone). The lowest values for all growth and yield parameters were observed under the control. However, the treatments had a non-significant effect on the harvest index. These findings highlight that integrating nutrient and weed management practices can effectively enhance wheat productivity and resource use efficiency under field conditions.
