Influence of fertilizers on the development of grape culture and bunch structural indicators

Samukh region is one of the main places in agricultural production, including grape production in Azerbaijan. Therefore, the study of the agrochemical properties of soils under vineyards, the current state of fertilizer introduction, increasing the efficiency of their use, a steady increase in soil fertility, yield and quality of grape harvest, as well as periodic environmental assessment of soils are urgent tasks that have both scientific, theoretical and practical value in the development of viticulture. In studies for the first time in the conditions of the Samukh region of Azerbaijan, on the basis of agrochemical and agroecological assessment of soils under vineyards, rational norms of fertilizers were determined against the background of manure, resulting in an increase in soil fertility, crop yield and quality of grape harvest. The article describes the effect of fertilizers on the number of common and fruit shoots, the number of clusters in one crop, as well as on the fruit coefficient of the total shoots and the fruit coefficient of fruit shoots...
