INFLUENCE OF MICROBIOLOGICAL PREPARATION AND MINERAL FERTILIZER ON THE FORMATION OF CHICKPEAS PRODUCTIVITY

Increasing the gross yield of chickpea seeds as a source of highly nutritious vegetable protein is one of the important aspects of ensuring national food security and nutrition of the population. The experiment to determine the effect of biological product based on nitrogen-fixing microorganisms, different doses of NPK, boron-containing fertilizer and their combinations on the formation of chickpea productivity was conducted in field conditions of a two-factor experiment in the conditions of the state enterprise “Experimental farm “Stepne” of the Institute of Pig Breeding and Agricultural Research of the NAAS” during 2023–2024. The results of the study showed that improving the nutritional regime of chickpea plants by inoculating seeds with a microbiological preparation based on nitrogen-fixing microorganisms, applying different doses of mineral fertilizers, foliar application of chickpea in the budding phase with microfertilizers and their combination improved the conditions for the formation of the leaf surface of plants and contributed to the extension of the duration of the period of its stay in an active state. Accordingly, the amount of absolutely dry aboveground mass accumulated by plants and the mass of seeds formed in beans increased. The most effective in this regard was the complex use of the microbiological preparation Anderiz (3.9 l/t) for pre-sowing inoculation of seeds and foliar application of crops with microfertilizer SmartGrow Bor-150 (1.5 l/ha) against the background of N15P60K60 application, which, along with the highest values of the photosynthetic activity of plants in crops, ensured the yield of chickpea seeds at the level of 2.56 t/ha.
