Abstract
Black gram (Vigna mungo L.) is an important pulse crop cultivated extensively in Asia, particularly in India, owing to its high protein content and ability to improve soil fertility through biological nitrogen fixation. Despite its economic and nutritional significance, black gram productivity remains low due to several biotic and abiotic constraints, among which weed infestation is a major factor. Weeds compete with the crop for nutrients, moisture, light, and space, resulting in yield losses ranging from 30 to 80% depending on weed density, species composition, and duration of competition. Traditional weed control methods, such as manual weeding and intercultivation, are labor-intensive and often constrained by labor shortages and increased production costs. Consequently, integrated weed management (IWM) has emerged as a sustainable approach that combines cultural, mechanical, biological, and chemical weed control methods to achieve effective weed suppression while minimizing environmental impacts. Recent advances in weed management include the development of selective herbicides, precision agriculture technologies, remote sensing, drone-based weed detection, and decision-support systems for site-specific weed control. Cultural practices such as optimum sowing time, crop rotation, intercropping, competitive cultivars, and mulching have also contributed significantly to weed suppression. The integration of these approaches enhances weed control efficiency, improves crop productivity, and reduces dependence on herbicides. However, challenges such as herbicide resistance, changing weed flora due to climate change, environmental concerns, and the limited adoption of advanced technologies among smallholder farmers continue to hinder effective weed management.This review summarizes the current status of weed problems in black gram cultivation, evaluates recent advances in integrated weed management strategies, discusses major challenges, and highlights future research directions. Emphasis is placed on sustainable and environmentally friendly weed management approaches that can contribute to improved productivity and profitability of black gram cultivation under changing agricultural scenarios.
