Hybrid corn variety NK 6275 is effective on barren land.

The application of scientific and technological advances to production, especially high-yield and high-yield hybrid corn varieties in recent years in Binh Thuan has contributed to increasing the productivity and output of corn in the whole region. In particular, the model of "demonstrating hybrid corn variety NK 6275" with a scale of 0.4 hectares in village 3, Dong Giang commune, Ham Thuan Bac district, which was organized by the Provincial Mountainous Service Center in coordination with relevant units in 2023, is an example.

For a long time, corn has been considered the second most important food crop after rice and is a popular crop grown in many different ecological regions, with a variety of planting seasons and farming systems. Corn plays a very important role in the crop structure. In particular, in recent years, hybrid corn production has been identified as an important food crop in the local crop structure.

The model of “demonstrating hybrid corn variety NK 6275” was recently implemented by Binh Thuan Mountainous Service Center in collaboration with Bac Giang Agricultural Technical Materials Joint Stock Company and Syngenta Vietnam Company Limited with the aim of selecting corn varieties with potential, high yield, good quality, resistance to external conditions and suitable for cultivation conditions in Binh Thuan. At the same time, improve the level of corn production of farmers and encourage farmers to expand the area in different ecological zones during the year.

According to the assessment of Mr. Nguyen Van Chi - Director of the Provincial Mountain Service Center, the NK 6275 corn variety demonstrated in the model has a high disease-free index, shows no signs of infection with pests and maintains green leaves from root to tip until harvest. In addition, the NK 6275 corn variety has a large, strong tripod root system, good support, and a hard stem, so it has a very good resistance to lodging. Another advantage of this corn variety is its good drought tolerance and can grow and develop well in barren, infertile soil conditions. In addition, although the demonstration model was carried out in hot, dry conditions, the plant still sets seeds well and has high fruit uniformity. The growing period of the NK 6275 corn variety is about 115 -120 days.

Also according to the Mountain Service Center, the demonstrated corn variety NK 6275 has a relatively uniform length (22 - 27 cm), large corn diameter, and small cob. This is an important factor determining the yield of the corn variety. Through the implementation of the model, it shows that the corn variety NK 6275 is an easy-to-grow, easy-to-care-for, low-nutrient variety, but the yield efficiency is very high, with an expected yield of 12.2 tons (dry)/ha. Thus, this corn variety has a wide range of adaptability, can be grown on poor soil or in areas where farmers are limited by old farming practices or pay little attention to investment and care...

With the potential, high yield, and good resistance of this corn variety, the Provincial Mountainous Service Center recommends that the seed supplier ensure the source and quality of the seed so that farmers can use it most effectively. In addition, localities, especially the mountainous communes of Ham Thuan Bac, should include the NK 6275 variety in the main variety structure for farmers to choose from, and include it in the main crop variety set, which is suitable and brings high economic value.

In the remaining months of 2023, the Provincial Mountain Service Center will continue to guide people to effectively and appropriately convert crop and livestock structures in each locality. In particular, the economic efficiency of hybrid corn, including the NK 6275 variety suitable for barren land, has contributed to stabilizing and developing the economic life of corn farmers, especially ethnic minorities in Ham Thuan Bac in particular and the whole province in general.

Binh Thuan Department of Agriculture and Rural Development informed: From the beginning of 2023 to now, the corn production area in the whole province is nearly 12,200 hectares, corn output reaches 64,592 tons. The total converted area on rice land in the first 9 months of 2023 is nearly 4,000 hectares, of which the area converted to corn is 1,142 hectares.
