Gordiyenko I. Local Method of Fertilization as Factor of Sweet Pepper Mineral Nutrition and Productivity Optimization in Conditions of Irrigation in the Left-Bank Forest-Steppe of Ukraine

Object - processes, which occur in the soil, some physiological-biochemical processes in plants and their changes at various ways of application of fertilizers under pepper sweet at cassette and usual technologies of its cultivation. The purpose - to prove a local way of application of mineral fertilizers under pepper sweet on the food and seed purposes in Left-bank Forest-steppe of Ukraine. Methods - general scientific and special. Theoretical results - influence of local application of fertilizers on a degree of mobility of phosphates, a nutritious mode of soil and on some physiological processes and photosynthetic activity of plants of pepper sweet is investigated at various technologies of its cultivation. Practical results - the expediency of local application of mineral fertilizers for increase of their efficiency is proved at cultivation of pepper sweet on chernozem typical clay loam with low humus content an irrigation of Left-bank Forest-steppe of Ukraine that allows to reduce expenses of nitrogen-potash fertilizers for 50 % and phosphoric by 75 % in comparison about earlier recommended doze of their application randomly. Novelty - for conditions of Left-bank Forest-steppe of Ukraine on chernozem typical clay loam with low humus content at an irrigation is established efficiency of sources-saving a local way of mineral fertilizers application under pepper sweet at usual and cassette technologies of their cultivation. The degree of implementatuon - the investigation results were used for the recomendations "The ways of soil fertility increasing under the conditions of present-day agriculture" (1999), also they were included into the programme for soil fertility protection and increasing of agriculture productivity in Kharkows region of Kharkow oblast for 2001-2010. The science works are put into practice on the research farm "Merefa", the Cooperative Agriculture Works "Chervony partizan" and the peasants private farm "Valentina" of the Kharkows region. Area of application - agriculture.
