The present investigation entitled “Effect of Organic and Inorganic Weed Management Practices on Growth, Yield, and Economics of Mung Bean (Vigna radiata L.)” was conducted during the summer season of 2025 at the Agricultural Farm, Career Point University, Kota, Rajasthan. The experiment aimed to evaluate the comparative effectiveness of organic and inorganic weed management practices on the growth, yield, and profitability of mung bean under irrigated conditions. The experiment was laid out in a Randomized Block Design with eight treatments replicated thrice, including control, weed-free, hoeing, organic mulching, and herbicidal combinations such as Imazethapyr, Fluazifop-p-butyl, and Propaquizafop + Imazethapyr. Results revealed a diverse weed flora dominated by Echinochloa colona, Cyperus rotundus, and Cynodon dactylon. Both organic and inorganic practices significantly reduced weed density and dry matter accumulation compared to the weedy check. Hoeing at 20 and 40 DAS and the combined herbicide treatment (Propaquizafop + Imazethapyr at 127 g ha⁻¹) recorded the highest weed control efficiency (>60%) and markedly improved crop growth attributes such as plant height, trifoliate leaves, branches, and dry matter accumulation. Yield attributes including pod number, grains per pod, and 100-seed weight were also maximized under these treatments.The weed-free and integrated herbicide treatments achieved the highest grain yields (10.6 and 10.2 q ha⁻¹, respectively) and biological yield (39.22 q ha⁻¹), with corresponding improvements in protein content (26.3%) and harvest index (27.02%). Economically, weed-free plots gave the highest gross and net returns, while the Propaquizafop + Imazethapyr combination offered the most favorable benefit-cost ratio (5.84). integrated weed management combining manual hoeing or selective herbicides proved superior in minimizing weed competition, enhancing yield, and ensuring profitability and sustainability of mung bean cultivation in semi-arid regions.
