Online Published on 24 April, 2024. Abstract Research experiment was carried out at the ICAR-Indian Agricultural Research Institute (IARI), New Delhi, during the winter season of2021-22 (28°382 N latitude, 77°102 E longitude; altitude 229 m above mean sea level) to study the effect of integrated weed management practices in vegetable pea. Randomized complete block design with three replications was used to set up eight treatments as detailed in methodology. Compared to conventional weed management practices, integrated weed management is a viable option for effective weed management in vegetable peas. Sequential application of pre- and post-emergence herbicides, in conjunction with other practices such as mulching and mechanical weeding, effectively reduces crop-weed competition at critical growth stages, giving the crop a competitive advantage to grow to its full potential, positively influencing biomass production and crop productivity and lesser reduction in crop yield. As a result, sequential application of pendimethalin as PE 750 g/ha fb mulch fb ready mix of (metribuzin + clodinafop) as PoE 270 g/ha may be recommended for effective weed control, profitability, and long-term sustainability of vegetable peas. Next option could be mechanical weeding, which suppresses weeds, reduces herbicide use, and improves soil aeration, better nutrient mineralization, better soil tilth, temperature regulation, and also improves the water holding capacity of the soil.
