Effect of various Weed Management Practices on Chickpea Crop Parameters
Abstract
This review synthesizes recent advancements in weed management for chickpea cultivation, emphasizing both mechanical and chemical approaches. Mechanical strategies, such as hand weeding at 30 and 60 days after sowing (DAS), significantly improve yield and seed protein content by effectively reducing weed competition. Strategic hoeing also enhances crop growth but requires careful timing to prevent increased weed density. Chemical control methods, including pendimethalin and imazethapyr, show effective weed suppression when applied correctly, though excessive use can lead to reduced yields. Combining pendimethalin with manual weeding provides optimal results, balancing robust weed control with plant health. This review highlights the importance of integrating mechanical and chemical strategies to achieve sustainable chickpea production. Future research should focus on optimizing these integrated approaches, developing eco-friendly herbicides, and adapting management strategies to varying climatic conditions to further enhance chickpea yield and quality.

Introduction
Weeds are a significant constraint in chickpea production, competing with the crop for essential resources such as nutrients, water, light, and space, leading to substantial yield reductions. Traditional mechanical methods like hand weeding and hoeing have long been the primary means of weed control, but they are labor-intensive and time-consuming. Chemical herbicides offer an alternative approach, providing more efficient weed management, though their use raises concerns about environmental impact, resistance development, and residual effects on soil health and crop safety.
This review synthesizes findings from various studies to offer a comprehensive understanding of the effects of both mechanical and chemical weed management practices on chickpea production. It evaluates the trade-offs between these methods, considering factors such as labor requirements, cost-effectiveness, environmental sustainability, and overall impact on crop yield. The aim is to guide the development of integrated weed management strategies that maximize productivity while minimizing adverse effects.
