Beating the Heat: Expert Tips to Protect Leafy Vegetables from Scorch and Wilt During Extreme Summers
With temperatures soaring across Maharashtra, leafy vegetable crops like spinach and coriander are struggling to survive even with regular irrigation. Experts from Mahatma Phule Krishi Vidyapeeth (MPKV) recommend using 50-70% shade nets, frequent light irrigation during early mornings, and potassium-based liquid fertilizers to build heat resistance.
As of April 22, 2026, the intense summer sun has become a formidable challenge for vegetable growers in Maharashtra. High temperatures are not only causing the leaves of crops like spinach, fenugreek, and coriander to droop and scorch but are also leading to root dehydration and stunted growth. To mitigate these losses, the Vegetable Research Center at Mahatma Phule Krishi Vidyapeeth (MPKV) has released a comprehensive management guide for farmers.
1. Smart Irrigation & Mist Cooling The traditional method of flood irrigation is often insufficient in extreme heat due to rapid evaporation. Farmers are advised to provide light but frequent irrigation, strictly during early morning or late evening hours. Providing a light water mist/spray on the leaves during the evening can significantly lower the plant's temperature and maintain its turgidity.
2. Shade and Physical Protection The use of 50% to 70% shade nets (green nets) is highly recommended to block direct solar radiation. For small-scale farmers who cannot afford shade nets, temporary structures using locally available materials to provide afternoon shade can prevent the crop's texture and color from deteriorating.
3. Nutritional Management for Heat Resistance Increasing the organic matter in the soil using farmyard manure or vermicompost helps the ground retain moisture for longer periods. Applying liquid fertilizers containing Potassium and Amino Acids can strengthen the crop's ability to withstand heat stress. However, farmers must strictly avoid applying heavy fertilizers during the hottest part of the day, as this can cause the roots to burn.
4. Post-Harvest Preservation Harvesting should only be done in the cool hours of the early morning or late evening to prevent the greens from wilting instantly upon exposure. Once harvested, keeping the produce in a cool, shaded area or using moist burlap sacks is essential for maintaining freshness before it reaches the market. By following these simple yet effective steps, farmers can ensure that their leafy vegetables retain their nutritional value and command better prices in the peak summer market.
