Bangladesh’s ongoing heatwave is raising concerns about agricultural production, especially Boro rice, the country’s main rice crop. The hot weather coincides with the flowering and grain formation stages of Boro rice, making it vulnerable to reduced yields.
Farmers are advised to keep rice fields flooded with 5 to 7 inches of water to maintain moisture and cool the plants. This will come at an added cost, but it’s necessary to protect crops. High temperatures also increase the risk of neck blast disease in rice. Farmers should be prepared to use pesticides to prevent this. Temperatures exceeding 35 degrees Celsius can harm pollination and lead to more underdeveloped rice grains.
Vegetables and fruits like mangoes are also susceptible to heat stress and may experience stunted growth or premature fruit drop. The Department of Agricultural Extension (DAE) is advising farmers on irrigation and pest control. They believe most crops will be protected if these measures are taken.
Up to 3% of Boro rice planted late in the season may be significantly affected by the heatwave. The Bangladesh Meteorological Department predicts the heatwave may continue until April 23rd. Farmers are urged to stay informed and take necessary precautions to protect their crops.
