To prevent mid-day depression in vegetables grown in sacs, several practical measures can be implemented. Using shade nets with 30-50% light filtration during peak summer hours (11 AM to 3 PM) is highly effective in reducing heat stress and water loss. Maintaining optimal moisture through mulching with straw or dried leaves helps conserve soil moisture and regulate temperature. Proper spacing between sacs ensures adequate air circulation and reduces competition for resources. Foliar application of potassium (1%) during high-temperature periods strengthens plant cells and improves water regulation. Additionally, scheduling irrigation for early morning or late evening, and using white-colored sacs instead of dark ones helps reflect heat and maintain cooler root zone temperatures, thereby minimizing the impact of mid-day depression on plant growth and yield.
