High-Yielding Summer-Autumn Rice Varieties

Date 02/04/2024

Choosing the right rice variety for the summer-autumn crop is crucial, determining both the quality and yield of the entire season. Which rice varieties are suitable for Vietnam’s climate and weather conditions during the summer-autumn season? Let’s explore this together with Viet Nga Fertilizer!

1. Characteristics of the summer-autumn crop season

For farmers, the summer and autumn seasons present several disadvantages for rice cultivation. This is because the weather is cold in the early mornings and at night, while the midday sun is intense, causing significant temperature fluctuations.

In addition, soil that is prone to acidity and salinity also greatly affects the growth and development of rice plants.

2. Criteria for selecting summer-autumn rice varieties

When choosing rice varieties for the summer-autumn crop, farmers should focus on the following important factors:

  • Climate conditions:

Rice varieties that can withstand changing weather conditions, especially drought and flood resistance, should be chosen.

  • Resistance to insect pests:

Changing weather and humid climate during the summer and autumn create favorable conditions for the development of pests and diseases; therefore, rice varieties with high pest and disease resistance are needed to minimize damage.

  • Short growing season:

Since summer and autumn have short growing seasons, choosing rice varieties with suitable growing periods is essential to ensure even ripening and avoid uneven ripening and crop failure.

  • Yield and grain quality:

Select high-yielding rice varieties to meet international export standards and deliver good profits for farmers.

  • The level of anesthesia decreased:

The rice variety should have a low degree of disintegration, meaning that after harvesting, the rice grains do not become excessively bran-laden during storage and transportation.

  • Local adaptability:

Prioritizing rice varieties that are well-adapted to local conditions helps optimize crop yield and quality.

3. New summer-autumn rice varieties suitable for different regions.

Nowadays, choosing the right rice variety for the summer-autumn crop is a top priority for farmers. Hybrid rice varieties that produce fragrant, sticky rice with high yields are favored because they meet the increasingly high demands of both domestic and export markets.

3.1. Mekong Delta

Dai Thom 8 rice variety is a new and highly popular variety for the summer-autumn crop due to its drought tolerance and pest and disease resistance. This variety has a growth period of only 90 to 95 days, producing delicious rice grains that are fragrant and sticky when cooked.

The Nang Hoa 9 variety is also very popular, with a short growing season of 95 to 100 days. It is drought-tolerant, salt-tolerant, and has good pest and disease resistance. The rice grains have a fragrant pandan leaf aroma, are sticky, and chewy.

3.2. Northern and Central Vietnam

Thien Uu 8 is a rice variety suitable for the summer-autumn crop season due to its wide adaptability, good drought tolerance, resistance to pests and diseases, and vigorous growth, resulting in high yields. The plant has a short growing season of 90-95 days per crop, producing high-quality rice with soft, white grains and a rich, delicious flavor.

The yield of different rice varieties can vary depending on many factors such as weather conditions, cultivation methods, fertilization, and soil conditions.

However, typically, rice varieties can achieve an average yield of 600-800 kg/1000 m², with the potential to reach 900 kg/1000 m². This is a rather impressive yield and can bring good economic benefits to farmers during the summer-autumn cropping season.

4. Summer-autumn rice varieties suitable for Vietnam’s climate.
