Studying the effect of potato products in extending the period of potato storage

Abstract

In this research, the cultivation and storage of potatoes grown in saline soils of Khorezm region at different levels with biopreparations, such as Bist (Pseudomonas putida) and Zamin-M (Bacillus subtilis, Bacillus megaterium and Pseudomonas stutzeri), were studied. In the experimental variants, there was 1.381 mg/kg of vitamin C, followed by 0.112 mg/kg of vitamin B6, 0.089 mg/kg of vitamin PP, 0.481 mg/kg of vitamin B12 and 0.092 mg/kg of vitamin B2 when Zamin-M was applied. Potatoes, which were treated with Zamin-M, contained 0.45% Fructose, 0.87% Glucose, 0.92% Sucrose, 0.04% Maltose, and it was higher than other biopreparations. During storage, the number of diseased nodules was 21.8% when treated with Earth ointment, it was 20% when treated with Bist, and it was 19.8% when treated with Zamin-M. The results showed that Zamin-M was suitable in soil and climate conditions of Khorezm region, especially for storage of potato, and it was found that Zamin-M contained microorganism, which activate the synthesis of phytohormones operating under stress. In comparison, the tested Zamin-M extended the shelf life of potatoes by 25% than the control variants.
