Economic efficiency of the application of nitrogen nutrition of persimmon under conditions of tobinsky district

Abstract

One of the biologically determined characteristics of Diospyros kaki is yield. It is influenced by the complex interaction of many factors and directly depends on soil and climatic conditions and technological care of plants, one of which is mineral nutrition. Diospyros kaki positively responds to nitrogen fertilizers. The article gives the results of the study showing the impact of doses of nitrogen nutrition on such indicators as productivity and economic efficiency of Diospyros kaki under conditions of Kubinsky district of the Republic of Azerbaijan. There was established that application of 90 kg and 120 kg/ha of nitrogen fertilizers increased productivity of the persimmon trees, thereby their economic efficiency. At the same time, the application of 120 kg of nitrogen per hectare was the most effective. However, due to the nitrogen accumulation in fruit, the application of 90 kg per hectare is considered to be the best option, where the profitability was 190.70 %.
