A field experiment was carried out to study the “Effect of planting geometry and weed management practices on weed dynamics, growth and productivity of greengram” at Instructional Farm, Alesur, Dau Kalyan Singh College of Agriculture and Research Station, Bhatapara, Chhattisgarh. The experiment was laid out in split plot design with three replications. The treatment comprised of three plant geometry i.e., 20 cm × 10 cm, 30 cm × 10 cm and 40 cm × 10 cm and five weed management practices i.e., weedy check, Pendimethalin 30 EC + Imazethapyr 2 EC (Pre-mix) @ 0.75 kg a.i. ha-1 (PE) fb 1 Hand weeding at 20 DAS, Pendimethalin 30 EC @ 1.0 kg a.i. ha-1 (PE) fb Imazethapyr 10% SL @ 100 g a.i. ha-1 at 20 DAS, Pendimethalin 30 EC @ 1.0 kg a.i. ha-1 (PE) fb Imazethapyr 35 WG+ Imazamox 35 WG @ 70 g a.i. ha-1 (Pre-mix) at 20 DAS and Weed free. Number of seeds per pod and test weight were not significantly influenced by plant geometry. Among the weed management practices, Pendimethalin + Imazethapyr (Pre-mix) fb 1 Hand weeding at 20 DAS recorded significantly higher number of pods per plant, number of grains per pod and test weight than Pendimethalin fb Imazethapyr + Imazamox (Pre-mix) Closer row spacing of 30 cm × 10 cm recorded significantly higher grain yields than row spacing of 40 cm × 10 cm and 20 cm × 10 cm. Pendimethalin + Imazethapyr (Pre-mix) fb 1 Hand weeding at 20 DAS although produced higher grain yield.
