Gyeonggi Agricultural Research Institute Urges Advance Management to Overcome Heat Wave Damage to Food Crops

The Gyeonggi-do Agricultural Technology Institute urged special attention to pre-cultivation management to prevent heat damage to food crops such as rice and soybeans, based on the weather forecast that the rainy season has ended earlier than expected and high temperatures are expected to continue for the time being. When high temperatures persist during the ear formation period of rice, there are concerns about poor pollination, lower grain filling rate (the rate at which grains mature), and decreased yield and rice quality. In particular, the proportion of complete grains (rice grains with an intact shape) decreases, affecting productivity. To prevent this, water should be frequently supplied from the end of tillering to enhance root vitality and lower paddy water temperature to induce stable growth. Additionally,

The Gyeonggi-do Agricultural Technology Institute urged special attention to pre-cultivation management to prevent heat damage to food crops such as rice and beans, based on weather forecasts indicating an earlier-than-expected end to the rainy season and continued high temperatures. When high temperatures persist during the ear formation period of rice, there are concerns about poor pollination, lower grain filling rates, and reduced yield and grain quality. In particular, the proportion of complete grains decreases, affecting productivity. To prevent this, frequent water flow should be maintained from the end of tillering to boost root vitality and lower paddy water temperature for stable growth. Additionally, silicon and potassium should be applied to prevent nutrient deficiencies, which are easily hindered during high temperatures. Moreover, proactive response is needed against diseases and pests such as leaf blight, moths, and stink bugs that are prone to occur in hot and ...
