The Central Cotton Research Institute (CCRI) has released an urgent advisory for cotton farmers in Punjab and Sindh, warning that a severe heatwave poses a significant threat to the crop during its critical growth stage. CCRI Director Sabahat Hussain emphasized that early-sown cotton is currently in the flowering and boll formation phase, making it highly susceptible to heat stress, which can lead to substantial yield reductions.
Temperature Forecast and Immediate Actions
The Meteorological Department has predicted temperatures ranging from 46°C to 50°C in several areas of both provinces over the coming days. To mitigate the impact, Hussain urged farmers to prioritize crop protection. Key recommendations include irrigating every four to five days, preferably during the cooler morning or evening hours, to minimize evaporation and maintain adequate soil moisture.
Fertilizer and Foliar Spray Recommendations
For crops that have already developed flowers, squares, or bolls, Hussain advised applying 10 to 20 kilograms of sulfate of potash (SOP) or muriate of potash (MOP) fertilizer through irrigation. Additionally, a foliar spray should be applied every 15 days to support boll setting and development. The spray mixture should include potassium sulfate, magnesium sulfate, zinc sulfate, copper sulfate, and borax dissolved in 100 liters of water per acre.
Role of Amino Acids in Heat Tolerance
Hussain highlighted the critical role of amino acids in enhancing heat tolerance. Farmers are advised to spray amino acids two to four times at 10-day intervals, combined with balanced nutrients to sustain plant vigor. All spray operations must be conducted in the evening for maximum effectiveness.
