Bacterial products help increase peanut productivity

Researchers from the Faculty of Agronomy, University of Agriculture and Forestry - Hue University have successfully researched and produced a nodule bacteria product to help increase peanut productivity; at the same time, contribute to soil improvement and environmental protection.

The nodule bacteria preparation works by a mechanism that, when injected, will help maintain and improve the chemical properties of the soil, such as increasing the content of humus, phosphorus, nitrogen, etc., while also increasing the number of beneficial microorganisms in the soil to decompose substances that help peanuts grow.

According to research, when applying nodule bacteria preparations, the total number of beneficial bacteria for peanut growth increased from 1.13 to 1.42 times; nodule bacteria increased from 1.16 to 2.99 times; phosphorus-solubilizing microorganisms in the soil increased from 1.7 to 2.61 times.

Currently, the nodule bacteria preparation is prepared in two types from isolated nodule bacteria strains NH1 and PC. Both have equivalent effects and have been produced.

Researchers recommend that the best results will be achieved when applied at a dose of 30-35kg per hectare of peanut land. In addition, manure, lime and a small amount of other fertilizers should be added to the soil.

In addition to Thua Thien-Hue, the nodule bacteria preparation is also suitable for peanut growing soil conditions in the Central provinces and cities.

According to researchers, the application of nodule bacteria preparations has been carried out in peanut growing areas of Thua Thien-Hue, including Tu Ha, Huong Chu, Huong Tra town; Huong Long, Hue city; Quang Vinh, Quang Dien district; Phu Mau, Phu Vang district...

By applying 35kg of nodule bacteria preparation to each hectare of peanut land along with some other fertilizers, it has helped increase peanut yield by more than 30%, peanut tubers are firmer, and the shape and weight of tubers are more uniform.../.
