Analysis of Agrotechnical Care of Diospyros kakiOrchard Grown in the Sheki-Zagatala Region of the Republic of Azerbaijan

Abstract

The article published a study of caring for the Diospyros kaki orchard in the Sheki-Zagatala region of the Republic of Azerbaijan. The development of Eastern persimmon depending on the row spacing system was studied and comparatively analyzed. The use of row spacing of green manure plants; when cultivating the row spacing of the eastern persimmon garden, we used legumes + field peas, which has a positive effect on plant growth; an increase in the number of fruits on the tree, the size and weight of the fruits was observed compared to the control. The influence of organic and inorganic fertilizers on the development of Diospyros kaki varieties was studied. The greatest development of 3-year-old trees was observed with the application of N50P20K35+20 tons/ha of inorganic fertilizer (manure). Our research in the conditions of the Sheki-Zagatala region showed that the location of the root system of Diospyros kaki on the surface requires frequent watering with low rates. During the growing season, good results were achieved by 5-6 times irrigation with a water norm of 350-400 m3 each time, since brown mountain-forest soil type predominates in our experimental plots. Among tree pruning methods tested, the vertical flattened form was found to be superior in both efficiency and overall yield. The influence of methods of pruning the crown of Diospyros kakion the yield of the 1st tree in all varieties increased. The Tamopan variety has the best results. Pruning trees using the free-growing method amounted to 154.0 kg, and the vertically flattened method amounted to 174.0 kg, which means an increase in yield from 1 tree by 11.5%. Our research has once again shown that, depending on the soil and climatic conditions of the region, it is necessary to carry out timely and comprehensive agrotechnical care of the orchard, as this will allow obtaining a high-quality harvest and a healthy garden.
