摘要

Weed menace in vegetable peas (Pisum sativum var. hortense Neilr.) production is one of the predominant yield limiting factor. We assessed the efficiency and sustainability of diverse weed management approaches in vegetable peas (Pisum sativum var. hortense Neilr.) cultivation, with a focus on weed dynamics, yield enhancement, soil health and herbicide residues. The present investigation compares a combination of mechanical weeding and herbicides, including pendimethalin, metribuzin, clodinafop, and quizalofop, as well as integrated treatments like pendimethalin followed by (fb) mulching fb metribuzin + clodinafop. These integrated approaches achieved a substantial reduction in weed population and weed dry matter accumulation 73.9% at 40 DAS and 68.6% at 70 DAS, while enhancing weed control efficiency (WCE) and weed control index (WCI). A key finding of this study lies in the dual focus on agronomic and ecological impacts, where yield parameters, such as pod and seed counts, improved significantly under these treatments, leading to a superior pod yield of 4.16 t/ha compared to 2.99 t/ha in the untreated weedy check (UWC). Importantly, the study highlights the contrasting effects of weed management on soil enzyme activities: mechanical weeding enhanced beneficial enzymes like dehydrogenase and alkaline phosphatase, whereas herbicide applications showed suppressive effects. Moreover, the research demonstrates the safety of these integrated treatments for consumer health and the environment, as no herbicide residues were detected in peas samples at harvest. By harmonizing high crop productivity with improved soil health and ensuring negligible herbicide residues, this study highlights the potential of integrated weed management practices as a sustainable and innovative approach for successful vegetable peas cultivation.
