Rice yields in the winter-spring season have decreased.
Harvesting rice in the Dien Thanh field (Dien Khanh district), Ms. Ly Lan said that this winter-spring season, her family sowed TH6 rice variety according to an order from a rice seed company. With nearly 1 hectare, she estimates a harvest of about 5 tons of rice, a slight decrease compared to the previous season. According to many farmers harvesting rice here, the main rice crop this year has lower yields than in recent years, mainly due to unfavorable weather conditions.

Similarly, Mr. Le Le from Van Binh Agricultural Cooperative (Van Ninh district) said that so far, the cooperative's 582 hectares of winter-spring rice have been harvested, with an average yield of about 50 quintals/hectare, lower than last year. During the growth process, the rice faced many strong winds, lack of sunshine when flowering, and a strong development of pests, which greatly affected the yield.
In Ninh Hoa town, Ms. Tran Thi Mai shared that each plot of rice this season only yielded 7-8 bags, compared to over 10 bags last year. Not only has the yield decreased, but the price of winter-spring rice is also lower, commonly at 7,500 VND/kg; seed rice is about 5 price points higher than regular rice.
According to the Provincial Department of Crop Production and Plant Protection, this year's winter-spring rice crop saw 19,252 hectares planted throughout the province. Nearly 15,000 hectares have been harvested so far, with an estimated yield of 64.58 quintals/hectare, a decrease of approximately 3 quintals/hectare compared to last year's winter-spring crop. The main reason is the overcast weather, with morning rain and cold temperatures, creating favorable conditions for pests and diseases to develop, especially rice blast disease.
Sow seeds on schedule and use short-duration varieties.
As usual, localities in the northern part of the province, such as Van Ninh and Ninh Hoa, tend to sow their rice earlier than other areas. Mr. Le Le said: "Except for some areas in high-lying fields, where the situation must be assessed according to the recommendations of the district and commune, the Van Binh Agricultural Cooperative has sown 565 hectares of rice for the summer-autumn crop. To date, the rice is developing well."
According to Mr. Nguyen Thien Hung, Head of the Provincial Department of Crop Production and Plant Protection, at the end of April, the Department of Agriculture and Environment issued a document guiding the summer-autumn crop production. Accordingly, it is predicted that from May to September, the province will experience hot and dry weather in the western and southern mountainous areas, then spreading to the coastal plains. From September onwards, the hot weather is expected to decrease. Although the water levels in reservoirs currently reach about 76% of their designed capacity, basically meeting demand, water conservation is mandatory given the upcoming low rainfall.
This year, the entire province will sow approximately 17,780 hectares of summer-autumn rice. Specialized agencies recommend farmers use short-day varieties with high yield, quality, and drought tolerance; only cultivate in areas with reliable water sources, and strictly adhere to the planting schedule. Irrigation system operators must review and adjust water supply plans; farmers are advised to dig ponds to store water and dredge canals to serve production. For harvested fields, farmers should quickly clean the fields and prepare the land for planting the summer-autumn crop according to the schedule to avoid unfavorable weather conditions and pests.
Specifically, the main varieties used include: ML48, ML202, ML214, OM4900; supplementary varieties include: TH41, TH6, OM7347, OM6976, Dai Thom 8 - all with a growth period of less than 100 days. On a single field, the variety structure must be rational, with each variety not exceeding 30% of the area. Concentrated sowing is necessary to avoid peak pest and disease outbreaks, facilitate water management, and make mechanized harvesting easier. For high-lying fields where irrigation is not readily available, localities should demarcate production areas and switch to suitable crops or seasons to minimize damage from drought.
