Risk of corn crop failure due to heat

Unusual heat and prolonged drought are concerns for summer-autumn corn crops.

In the past four years, climate change has been quite erratic and this year is no exception when in the South, the cold weather lasted from after Tet until March, and by early June, it was still extremely hot and stuffy.

It can be said that because the rainy season this year came later than every year, the sowing schedule for dry crops that mainly use rainwater such as hybrid corn and beans has been delayed. The corn fields planted to welcome the rain in the Eastern and Central Highlands regions are in a "half-crying, half-laughing" situation, some grow unevenly, some plants die, some leaves wither and regular fertilization cannot be done, leading to potential risks such as corn with the cob ends abandoned due to lack of nutrition, phase deviation (corn flowers when the silk grows too late), possibly sparse grains, no seeds, corn husks that produce many kernels without seeds...

Mr. Truong Dinh Cu, Hamlet 4, Lam San Commune, Dong Nai, lamented that the corn growth rate is not up to 70% but he still has to continue taking care of it in time for the second crop. Not only Mr. Cu but many other farmers also share this situation.

In Thanh Chuong, Tan Ky, Do Luong districts, Nghe An province, tens of thousands of hectares of hybrid corn are drying up and dying without seeds due to prolonged, severe heat.

Dr. Tran Kim Dinh, Southern Institute of Agricultural Sciences, predicts that corn yield this crop may decrease compared to previous years due to poor grain formation, open fruit, sawtooth corn, rat-tail corn... which may occur on a large scale and in most provinces and cities.

According to Dr. Tran Kim Dinh, farmers should choose drought-resistant varieties with fast germination to overcome harsh initial weather conditions. Make sure the soil is moist enough before sowing so that the seedlings have enough water to grow./.
