Innovation in rice variety structure for 2024 winter-spring crop

Annual crop production often faces many difficulties in terms of weather and pests, so the provincial agricultural sector has directed localities to flexibly change the rice variety structure to adapt to the production situation and consumption market. In the current crop production, localities have proactively selected varieties with high yield, resistance and good quality to continue to structure the main variety set and ensure productivity and value on the cultivated area.

Xuan Tan Agricultural Service Cooperative, Truong Xuan Commune (Tho Xuan) produces tray seedlings for the 2024 crop production.

Xuan Tan Agricultural Service Cooperative, Truong Xuan Commune (Tho Xuan) has developed a plan to plant nearly 150 hectares of rice in the 2024 winter-spring crop. Regarding the seed structure, the Cooperative plans to reduce the proportion of hybrid rice, increase the proportion of pure rice and high-quality varieties that are popular in the market. Mr. Nguyen Van Nhan, Director of the Cooperative, said: Changing the seed structure in production is an inevitable trend, not only reducing production costs in the field but also ensuring easy consumption of products, bringing higher economic efficiency. Therefore, when building the seed structure for the season, the Cooperative's management board has taken into account the actual production conditions, value and output of the products. In particular, to promote the advantage of being a locality with strong winter crop production, the Cooperative has instructed people to mainly produce early-season rice, with varieties with a growth period (TGST) from 105 days to less than 115 days, such as: TBR97, TBR87, TBR225, Bac Thinh, Dai Thom 8, Khang Dan Mut Mut... Along with that, the Cooperative has proactively contacted reputable and quality rice seed production units to supply people and provide technical guidance on fertilization and pest control on rice plants in the autumn-spring crop.

In the 2024 winter-spring crop, Tho Xuan district strives to cultivate 7,450 hectares of rice. To improve production efficiency, the district has innovated the rice variety structure, reducing the area of ​​hybrid rice and increasing the area of ​​high-quality pure rice and glutinous rice. Accordingly, the district aims to produce about 1,000 hectares of hybrid rice, 5,850 hectares of pure rice and about 600 hectares of glutinous rice. At the same time, it focuses on maximizing the early season to avoid storms, pests and diseases at the end of the season and creating conditions to expand the winter crop area. By June 20, the whole district had basically completed the cultivation of the entire rice area within the crop calendar. At the same time, measures to care for and prevent pests and diseases were implemented to ensure a comprehensive success of the crop.

Nong Cong district aims to produce about 9,300 hectares of rice in the 2024 crop. With low-lying terrain that is prone to flooding in the rainy season, the district has proactively arranged 100% of early-season rice, prioritizing the use of purebred rice varieties with high quality rice. At the same time, each commune arranges 3-4 main varieties, each field only structures 1-2 rice varieties for production in concentrated areas and continues to maintain and expand production models according to VietGAP standards. By June 17, the district has completed 100% of the sowing area, and is proactively regulating water sources reasonably for rice care in each area and field, creating favorable conditions for rice growth and development.

In the 2024 crop season, Thanh Hoa aims to develop about 112,900 hectares of rice. Of which, the area of ​​glutinous rice is 11,000 hectares (accounting for 9.74%) or more. The Department of Cultivation and Plant Protection has developed a structure of key rice varieties for crop production in the province. In particular, for early season rice, depending on the soil, use rice varieties with a maturity period of less than 105 days to 125 days, such as: TBR97, TBR87, TBR225, Bac Thinh, Thien Uu 8, Dai Thom 8, Du Huong 8, Huong Binh, VNR20, VNR88, TBR97, TBR87, TBR89, MHC2, Ha Phat 3, Thanh Huong, Tan Uu 98, Kim Cuong 90, Lam Son 8, ADI 168, ADI 28, HANA318, HANA167, Hat Ngoc 9... For main season rice, use rice varieties with a maturity period of less than 135 days, such as: BC15, HANA112, HANA7, DQ11, ND502, Thanh Huong 8, Thai Huong, Q5, VT404, Thai Xuyen 111, Phuc Thai 168, Phu Uu 978, ADI73, Thuy Huong 308... and glutinous rice varieties: Nep Huong, A Sao, King 6, Nep Thom 86, Nep Co Tien, Nep 98, DT52... For late-season rice, arrange varieties with a growth period of 150 - 165 days, and temperature-sensitive varieties such as Nep Hat Cau, Nep Cai Hoa Vang, and local glutinous rice...

Because winter-spring crop production often encounters complex and unpredictable weather and climate conditions such as rain, storms, floods, etc., the Department of Agriculture and Rural Development has directed localities to expand the area of ​​early-season tea cultivation, minimize late-season tea cultivation, both ensuring safe production and creating land funds for winter-spring crop production. At the same time, guide people to choose varieties with high yield, good resistance and quality to continue restructuring the main variety set. As of June 22, the whole province has planted 74,456.6 hectares/112,900 hectares of winter-spring rice, reaching 66% of the plan. To ensure the success of the 2024 winter-spring crop production target, the agricultural sector has been directing localities to speed up the progress of land preparation, rice cultivation and autumn-spring crops, striving to plant all planned areas within the time frame. Encourage increased use of transplanting methods, limit sowing and transplanting. In particular, it is necessary to focus on producing early season rice and main season rice on winter crop land; closely monitor weather developments, regularly check for pests and diseases to have proactive plans and be ready to deal with unusual weather developments such as prolonged heat, drought, heavy rains and storms, flooding and harmful pests and diseases... to ensure an average yield of 54.5 quintals/ha, with the total rice output of the province reaching 615,305 tons in the winter-spring crop.
