Using probiotics in pepper cultivation

After many years of research, Tay Nguyen University has found measures to use probiotics in cultivation of pepper.

>>>Process of planting, caring and protecting pepper trees

Accordingly, the school has built reasonable production models to ensure sustainable cultivation, bring high economic efficiency, environmentally friendly, bring new awareness to people in cultivating trees. pepper.

The scientists used chitin, chitosan and chitosan oligomer probiotics for pepper in the basic construction period.

Biological products are extracted from shrimp shells, insects, fungal cell walls. These are non-toxic, biodegradable and environmentally safe ingredients.

The components of chitosan and chitosan oligomer have growth stimulating activity in plants, increase the number of beneficial microorganisms, limit harmful fungi in the soil and enhance plant resistance system for plants.

Applied to production, preparations are irrigated to pepper plants three times, each time separated by 15 days. After three months, the amount of mold and bacteria in the soil increases rapidly.

Most of these bacteria and fungi have the ability to synthesize enzymes that dissolve cell walls of pathogenic fungi and some insects, helping pepper plants to increase resistance to fungi. disease in the soil.

During the cultivation process, when applying chitosan and chitosan preparations, oligomer has significantly reduced the number of fungi causing Fusarium for pepper plants.

In addition to indirect mechanisms to increase the amount of mold and actinomycetes, chitosan and chitosan oligomer preparations also have direct Fusarium antifungal activity. Fusarium fungi were completely inhibited when cultured on medium supplemented with chitosan and chitosan oligomer with concentration of 0.1-0.15%.

These probiotics also reduce the number of nematodes in pepper roots up to eight times that of plants without inoculants.

On the other hand, when spraying chitosan oligomer with concentration of 200mg / l on leaves, the amount of chlorophyll in pepper leaves increased nearly 50%. The tree is stimulated to grow the main stem and branches grow faster.

In fact, the production of chitin, chitosan and chitosan oligomer bio-products, when irrigated or applied to the soil, has a clear effect in improving the microbial flora in pepper soils, contributing to reducing Significant amount of fungi causing disease in pepper plants.

Acquiring the results of research and experiment of Tay Nguyen University, Dak Nong Department of Agriculture and Rural Development is applying the use of biological products to the cultivation of pepper trees during the basic construction period. many farmer households and achieved positive results. In particular, popular application in many localities planting pepper such as Dak R'lâp, Cư Jut district and Gia Nghia town.

Pepper trees are industrial plants with high economic value but now the cultivation of these trees by households is facing many difficulties. The main cause is the widespread destruction of yellow-leaf disease quickly and slow death of yellow leaves caused by viruses.

Currently, chemical control measures are not effective and cause environmental pollution. The successful use of probiotics in pepper farming has brought great prospects for sustainable production development. In the coming time, scientists continue to study bio-products to apply pepper cultivation in the business period, in order to improve production efficiency for farmers.
