Qoraqalpog‘istonda kartoshka (Solanum tuberosum L.) yetishtirishda bioo‘g‘itlar va resurstejamkor texnologiyalarning agroekologik samaradorligi

This article investigates the effectiveness of biological fertilizers and resource-saving agrotechnologies for potato (Solanum tuberosum L.) cultivation under the natural, climatic, and soil conditions of the Republic of Karakalpakstan. Based on field experiments, the effects of biological fertilizers on potato plant growth and development, tuber formation, yield, and product quality were evaluated. The results showed that, compared with the control, the application of biofertilizers increased plant height by 8-12% and the number of stems by 10-15%, while the number of tubers per plant increased from 7-8 to 9-11 tubers. Yield increased from 22-24 t/ha to 27-32 t/ha, corresponding to an approximately 21-36% increase compared with the control. The starch content of the tubers was 1,5-2,5 percentage points higher than in the control. In addition, the application of biological fertilizers enhanced soil biological activity and improved the uptake of nutrients by plants. The findings demonstrate that integrating biological fertilizers with resource-saving agrotechnologies is a promising agroecological approach for improving the efficiency of potato production under the conditions of Karakalpakstan.
