The effect of folic fertilization on yield and quality indicators of plum fruits in arid conditions of the Astrakhan region

Abstract

The article presents the results of studying the effect of foliar feeding on the yield and quality of plum fruits. The studies were carried out on the irrigated plot of the orchard of the Federal State Budgetary Scientific Institution "Pre-Caspian Agrarian Federal Scientific Center of the Russian Academy of Sciences" of the Astrakhan Region. As a result of the study, it was found out that the application of macro- and microfertilizers, which are part of the preparations Aquarin, Ultramag boron, Ultramag calcium, is an important factor that improves the commercial qualities of plum fruits. With the foliar top dressing with macro- and microelements, it is possible to control the yield and quality of fruits. The studied fertilizers have a positive effect on the weight, size and quality of plum fruits. The highest average productivity was noted in plum varieties Velikaya sinyaya - 12.3 kg/tree, Volgogradskaya - 11.5 kg/tree. Among the studied varieties, the maximum weight and size of the fetus was noted in the Zainap and Volgogradskaya varieties, which ranged from 48.5 to 54.6 grams.
