A field experiment was conducted during Kharif season of 2022 at agricultural research block, School of Agricultural Sciences, Shri Guru Ram Rai University (SAS-SGRRU), Dehradun, Uttarakhand to study the effect of non-chemical weed management methods on weed growth and greengram (Vigna radiata L.) yield. The experiment was laid out in factorial randomized RBD comprising 2 factors replicated thrice. First factor, crop geometry comprised of 20 × 15 cm, 25 × 12 cm 30 × 10 cm spacing maintained between row to row and plant to plant, respectively. The second factor was non-chemical weed management treatments including: weedy check, hand weeding (HW) once at 20 days after seeding (DAS) + mulching, and hand weeding twice at 30 and 45 DAS. Crop geometry and weed management treatments significantly influenced all the growth parameters, yield attributes and yield of greengram, weed density and biomass. To improve the productivity of greengram by managing weeds effectively in the Doon valley area of Uttarakhand, hand weeding once at 20 DAS + mulching along with crop geometry of 30 cm × 10 cm may be recommended, as they recorded a significant improvement in growth and yield parameters and greengram yield, compared to other treatments.
