Effect of different weed management practices on weeds dynamics, growth and productivity of cowpea (Vigna unguiculata L.)

A field experiment was conducted at the Instructional Farm of Agronomy, Rajasthan College of Agriculture, Udaipur during kharif, 2024 to study the “Effect of Different Weed Management Practices on Weeds Dynamics, Growth and Productivity of Cowpea (Vigna unguiculata L.)”. The experiment was laid out in randomized block design comprising of 12 treatment combinations with three number of replications. Results of this experiment revealed that all weed observations i.e., weed density, weed dry matter accumulation, WCE recorded lowest under W₂ [Two hand weeding at 15 and 30 DAS] but in yield attributes and yield (grain, stover and biological) were maximum under W₁₂ (weed free). Additionally, W₁₁ [Pendimethalin @ 0.5 kg ha^-1 (PE) + Imazethapyr @ 0.075 kg ha^-1 20 DAS (PoE)] recorded significantly highest nutrient content and uptake by grain as well as stover yield among herbicidal treatments. However, lowest growth, yield attributes and yield were observed under weedy check (W₁).
