Abstracts

Based on the data from hydro-meteorological stations, combined with the soil-specific data of Gia Lai province, the study selected the Palmer index to describe the drought. It was suitable with growing season to develop a monthly agricultural rezoning map for Gia Lai province. The study also showed that the number of days over years and the total number of days in the growing season tended to increase from the northern districts to the southern districts of the province and decreased from the eastern districts to the western districts. According to the time distribution from November to April, drought in Gia Lai province tended to increase from November to January, February and gradually decreases to April. According to spatial distribution, drought might decrease from west to east and from north to south. Through this study, it was shown that the areas suffered from agricultural drought were mostly the northwestern districts of the province in January.
