Tóm tắt

The data on daily sunshine hours, daily average temperature and daily precipitation collected from 143 meteorological stations across Viet Nam for 2018 and 2019 years is used for this studying. The effects of adverse weather conditions of light, temperature, wetness and drought during three main stages of rice growth and development in the 2019 summer-autumn is assessed and compared with the 2018 summer-autumn because rice varieties and cultivation conditions for two consecutive seasons are less different. Specifically, the assessment results show that adverse weather conditions affect the 2019 summer-autumn rice less than the one in 2018, which is one of the reasons contributing to the increase of 2019 rice productivity about 2 % compared with 2018.
