COMPARATIVE ANALYSIS OF INDICATORS OF ECONOMIC EF-FICIENCY OF CULTIVATION OF CHERRY SEEDLINGS WITH DRIP IRRIGATION

Background. The increase in fruit production to a deficit-free volume of consumption by the population and the needs of industrial processing is due to the need to expand the area of garden plantings. An integral part of the organization of the laying of garden plantings is the nursery industry that grows planting material. A lot depends on the quality of the planting material. The choice of a seedling affects the further growth, development, fruiting, yield and immunity of the future fruit tree. In the conditions of a nursery of stone crops of open ground, it is important to determine the irrigation regime, which, in combination with the use of fertilizers, will provide the highest yield of seedlings while saving all types of resources. Purpose. To determine the economic efficiency indicators of the recommended irrigation technology in combination with mineral fertilizing of cherry seedlings. The assessment of economic efficiency in our experiments was carried out by calculating the profit received, taking into account all costs in the nursery and the level of profitability. Materials and methods. The object of research was annual cherry seedlings of the Vasilisa variety. The scheme of two-factor experience provided for the study of three options for each factor. Factor A is the water regime of the soil and factor B is mineral fertilizing. Results. It has been proved that when growing seedlings of stone crops on light chestnut soils, the effectiveness of fertilizer application in combination with a differentiated irrigation method is high, in which the depth of soaking and, accordingly, the irrigation rate changes. Conclusion. The analysis of the data on the economic efficiency of growing seedlings showed that at the selling price of seedlings 170 (grade 1) and 120 (grade 2) rubles per seedling, when growing them against the background of the A3 water regime in combination with top dressing with Izabion and Master, the profitability was the highest and amounted to 155 and 154%. At the same time, the profitability of the control variant was 99%.
