The article presents the results of many years of research on the effect of foliar dressing with complex fertilizers and humate on photosynthetic activity and productivity of potato plants of Gala and Latona varieties. The following options have been studied: 1) without treatment (control); 2) dressing with Ekorost humate at a dose of 0.2-0.4 l/ha; 3) dressing with micronutrient Strada N at a dose of 3-5 l/ha; 4) dressing with micronutrient Strada R at a dose of 3-5 l/ha. The treatment was carried out twice during the growing season: when full shoots appeared and 14 days after the first one. Determination of the leaf area and calculation of the photosynthetic potential were carried out according to the VNIIKH method (1967) three times during the growing season in the following phases: budding, flowering, and the beginning of withering away of lower leaves. The crop was harvested by the method of continuous harvesting of the accounting area of the plots with weighing. The effectiveness of the studied agrotechnical methods has been proved. The best variant of the investigated ones is the use of Strada R. The plants of this variant formed a more powerful assimilation apparatus and had the highest photosynthetic potential, which ultimately affected the yield of tubers. The increase in the yield of two varieties of potatoes was 21.8-23.1 % in relation to the control. Gala variety turned out to be more responsive to the action of vegetative treatments in comparison with Latona variety.
The article examines the effect of foliage spraying with complex micronutrient fertilizers Strada N, Strada R and humate Ekorost on the preservation of potato tubers of Gala and Latona varieties. The data on natural loss and total quantitative losses of experimental and control tubers after eight months of storage are given. A decrease in the natural loss of mass and absolute waste of tubers in the variants with the use of complex micronutrients has been revealed. Micronutrient Strada R with predominating phosphorus had the greatest effect on increasing the preservation of tubers. It is shown that the use of Ekorost humate does not have a pronounced effect on increasing the storage capacity of tubers, although it leads to a slight decrease in the natural loss of mass of two potato varieties.
Проблема и цель. В настоящее время при выращивании картофеля отмечается негативная тенденция, заключающаяся в использовании повышенных доз минеральных удобрений при одновременном сокращении внесения органики. Альтернативой традиционным минеральным удобрениям могут стать комплексные микроудобрения и гуминовые препараты. Цель работы – изучение влияния некорневых подкормок комплексными микроудобрениями и гуминовым препаратом на биометрические параметры роста и развития картофеля. Методология. Исследования проводили на двух сортах картофеля раннеспелой группы – Гала и Латона. Для некорневых подкормок использовали микроудобрения Страда N, Страда Р и гуминовый препарат Экорост. Картофель выращивали в 2017-2019 гг. в учебном хозяйстве РГАТУ на серой лесной почве. Варианты опыта: 1) контроль – без вегетационной обработки; 2) обработка гуматом Экорост в дозе 0,2-0,4 л/га; 3) обработка микроудобрением Страда N в дозе 3-5 л/га; 4) обработка микроудобрением Страда Р в дозе 3-5 л/га. Обработку проводили дважды – при появлении полных всходов и через 14 дней после первой. Остальные элементы агротехники культуры не различались по вариантам и были общепринятыми для нашей зоны. Определение биометрических параметров картофеля проводили по методике ВНИИКХ (1967) в три срока: в фазу бутонизации, цветения и начала отмирания ботвы. Результаты. Экспериментально доказано положительное действие некорневых подкормок комплексными микроудобрениями и гуминовым препаратом на динамику изменения таких биометрических параметров картофеля, как высота растения, количество стеблей, масса и площадь листьев, масса клубней. Заключение. Наиболее эффективным вариантом является некорневая подкормка микроудобрением Страда Р, использование которого улучшает условия развития растений, ускоряя рост ассимиляционного аппарата, что в конечном итоге отражается на продуктивности картофеля. Problem and purpose. Currently, when growing potatoes, there is a negative tendency, which consists in the use of increased doses of mineral fertilizers while reducing the introduction of organic matter. Complex micronutrient fertilizers and humic preparations can become an alternative to traditional mineral fertilizers. The purpose of the work is to study the efect of topdressing with complex micronutrient fertilizers and a humic preparation on biometric parameters of growth and development of potatoes. Methodology. The research was carried out on two varieties of early maturing potatoes - Gala and Latona. For topdressing, micronutrient fertilizers Strada N, Strada R and humic preparation Ekorost were used. Potatoes were grown in 2017-2019. in the educational farm of RSATU on gray forest soil. Experimental options were as it follows: 1) control - without vegetative treatment; 2) treatment with humate Ekorost at a dose of 0.2-0.4 l/ha; 3) treatment with micronutrient Strada N at a dose of 3-5 l/ha; 4) treatment with micronutrient Strada Rat a dose of 3-5 l / ha. The treatment was carried out twice - when full shoots appeared and 14 days after the frst treatment. The rest of the elements of agricultural cultivation did not difer in variants and were generally accepted for the zone. The determination of biometric parameters of potatoes was carried out according to the method of VNIIKH (1967) in three terms: in the phase of budding, fowering phase and the beginning of top withering away. Results. The positive efect of topdressing with complex micronutrients and a humic preparation on the dynamics of changes in such biometric parameters of potatoes as the plant height, number of stems, mass and area of leaves, mass of tubers has been experimentally proved. Conclusion. The most efective variant is topdressing with Strada R micronutrient, the use of which improves the conditions for plant development, accelerating the growth of the assimilation apparatus, which ultimately afects the productivity of potatoes
