New Polyfunctional Biorationals Use to Achieve Competitive Yield of Organic Potatoes in the North-West Russian Ecosystem

Summary

This research demonstrates how organic farming methods using beneficial microorganisms and special compost can help grow healthy potato crops without chemical pesticides. The study found that combining naturally-derived biological treatments with organic fertilizer significantly improved potato yields and protected plants from diseases. Impacts on everyday life: • Provides safer, chemical-free methods for growing organic potatoes • Demonstrates sustainable alternatives to synthetic pesticides and fertilizers • Helps farmers produce higher quality organic potato crops • Contributes to environmentally-friendly food production methods • Supports development of natural plant disease control products

Background

Potato is the fourth most important food crop globally after maize, wheat and rice. Russia produces about 20 million tons annually. Organic farming faces challenges in potato production, particularly disease control and providing sufficient nutrients. Biological control using biorationals and biologicals offers promising solutions for organic and sustainable agriculture.

Objective

To characterize the efficacy of new polyfunctional biologicals and special organic compost to provide maximum possible yields in organic potatoes under prevailing weather conditions. This included evaluating experimental batches of biological formulations (Kartofin SC, Kartofin MR SC) and organic fertilizer BIAGUM for their effects on plant development, disease protection, and yield formation.

Results

The combined use of BIAGUM and biologicals increased tuber yields by 4.3 t/ha under optimal conditions and 2.2 t/ha under dry conditions compared to controls. Plant growth rates and foliage increased 1.2-1.3 fold, with productive stems increasing 1.6-fold regardless of conditions. The biologicals showed 90% efficacy against fungal diseases under optimal conditions and 65-75% under drought conditions. BIAGUM demonstrated 45-50% disease reduction effectiveness.

Conclusion

The joint application of special compost BIAGUM and new polyfunctional biologicals provided significant increases in potato yield and quality under both optimal and dry growing conditions. The biologicals demonstrated high efficacy in controlling fungal diseases, while BIAGUM contributed to both yield improvement and disease reduction. The degree of stimulating effect was proportional to compost dose.
