Context: A recent study commissioned by the Federation of Seed Industry of India (FSII) revealed significant crop productivity losses caused by weeds, amounting to ₹92,000 crore ($11 billion) annually. The study focused on understanding weed-related crop damage and recommending strategies for better weed management.
Key findings:
- Impact on crop yield: Weeds are responsible for 25-26% yield losses in kharif crops and 18-25% in rabi crops across India.
- Affected crops: The study covered seven major crops, including rice, wheat, maize, cotton, sugarcane, soybean, and mustard, from 30 districts in 11 States.
- Farmer and dealer input: Over 3,200 farmers and 300 dealers were consulted, along with experts from Krishi Vigyan Kendras and the Agriculture department.
- Economic Costs: Farmers spend ₹3,700 to ₹7,900 per acre on weed control, with weeds being a leading factor in crop losses among biotic stresses.
- Weed management recommendations:
- Herbicides and mechanization.
- Crop rotation and cover cropping.
- Biological control measures.
- Cost reduction: Implementing these strategies could reduce costs by 40-60% compared to traditional methods.
