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.

Storage of potatoes with the help of biopreparations

“…When potatoes are stored optimally during long storage period, the tubers do not lose their properties and do not sprout until the new crop is ripe. Preservation of potatoes is related to a number of biological factors: structure, quick healing of mechanical damage, rest period, chemical composition, growing conditions [5][6][7][8][9][11][12][13]. According to the sources, the factors determining the storage period of potatoes are the storage period and the amount of loss, and the rest period stage (physiological rest period) after harvesting the tubers is its biological characteristic.…”

“…According to the sources, the factors determining the storage period of potatoes are the storage period and the amount of loss, and the rest period stage (physiological rest period) after harvesting the tubers is its biological characteristic. Its duration lasts up to 1-3 months, depending on the variety, growing conditions and storage conditions [11][12][13][14].…”

“…The main feature of biopreparations, compared to other means of plant protection, is to act on harmful organisms by stimulating their own defense mechanisms. The use of this feature helps to maintain ecologically stable agrosystems by utilizing the full potential of integrated protection of plants in plant science practice [4][5][6][7][13][14][15]. A group of biologically active compounds that act as biostimulants on plants are also called growth regulators.…”

“…When used together, it reduces the phytotoxicity of chemical pesticides. Immunization properties of plants against rhizoctoniosis, alternaria, scab and above-ground part and roots have been noted [9][10][11][12][13]. According to the researches of scientists of foreign countries, the regulators that actively affect agricultural crops, their representatives affect potato damage and quality indicators.…”

“…That is why in many countries these substances are currently used as a biotechnological factor as an important tool in the cultivation of various agricultural crops in a system of complex measures. They are successfully used to increase the fertility of seeds, to catch the seedlings and cuttings of fruit and vegetable crops, to accelerate the germination of apples, tomatoes, legumes and other crops, and to increase the quantity and quality of the obtained harvest [6][7][8][9][11][12][13].…”
