Recently, many areas in Dak Lak - the largest coffee growing area in the country - have continuously suffered from unseasonal rain, causing farmers to worry.
Mr. Doan Van Doai (village 3, Ea Khau commune, Ea H'leo district) said that in recent days, unseasonal rains have appeared frequently, causing disadvantages for coffee trees.
At this time, the plant needs to dry to differentiate the flower buds, but the rain interrupts this process, leading to uneven blooming of the flowers, affecting productivity and quality.
"It rained too early, the plants did not have enough time to differentiate their flower buds, causing the flowers to bloom in opposite places and unevenly. In addition, rainwater also contains acid, which is not good for plants when they are flowering and bearing fruit, Mr. Doai worried.
Mr. Nguyen Van Toan (Cu M'gar commune, Cu M'gar district, Dak Lak) said that heavy rain when coffee trees are in the sleeping stage will stimulate the underdeveloped roots.
If there is a prolonged hot or dry period, the young roots are vulnerable, reducing vitality and nutrient absorption when growing fruit.
To limit negative effects, after unseasonal rains, Mr. Toan proactively adds nutrients, helping the garden increase resistance.
Unseasonal rains also create conditions for diseases to develop, especially diseases of dry branches, dried fruits and fallen leaves.
High humidity also makes pinkish, leaky iron and pests attack more strongly, affecting coffee bean productivity and quality.
According to the Department of Agriculture and Rural Development of Dak Lak, the whole province currently has more than 212,000 hectares of coffee - the largest area in the country.
However, climate change is posing many challenges, requiring farmers to take flexible response measures to protect coffee productivity and quality.
