RESEARCH OF THE INFLUENCE OF AGROECOLOGICAL CONDITIONS AND MINERAL FERTILIZERS ON THE PRODUCTIVITY AND QUALITY OF TOMATOES IN THE GREY-BROWN SOILS OF ABSHERON BASED ON MODERN TECHNOLOGIES

The main purpose of the research is to study the agroecological characteristics of the grey-brown soils of Absheron based on modern methods and instruments, to map the peninsula using satellite imagery based on GIS, to increase the productivity of the sort of tomato “Ilkin” and obtain a quality product in accordance with local soil and climatic conditions, by introducing optimal norms of fertilizers in the conditions of Absheron in order to ensure food security. The following tasks were performed to achieve the objectives of the research: Drawing up of a route map for field research on the basis of map-fund materials in the territory of the Absheron Peninsula; Conducting soil research at selected reference points of the peninsula, taking soil samples from genetic layers along the soil profile and studying the agroecological characteristics of soils, compiling sections that characterize the area in accurate geographical coordinates based on GPS; Determination of humus, nitrogen, phosphorus, potassium, pH,Nelectrical conductivity, dry residue, absorbed bases, hygroscopic moisture, carbonate, macro- and microelement content and granulometric composition in soil samples taken; Compilation of Digital Elevation Model map, Land Surface Temperature maps and Normalized Difference Vegetation Index map of Absheron Peninsula using satellite images and multispectral images with the most modern calculations and methods GIS-based; Study of agrochemical and physicochemical properties, microelement and mineralogical composition soils under vegetable in the field of experiment; Research of the effect of fertilization under the tomato plant on the dynamics of the amount of nutrients accumulated in the soil and in the plant; Research of the effect of different norms of urea and ammonium nitrate fertilizers on the productivity and quality of tomato plants on the background of 10 t/ha manure + P90K90; Determination of the economic efficiency of the use of fertilizers for tomatoes in the conditions of Absheron.
