An increased intensity of agricultural mineral fertilizers’ use to raise crop yields has disrupted the soil’s natural balance. Researchers worldwide continually analyze biological factors in farming systems as a transitional stage to organic farming to increase soil fertility. The presented study pursued evaluating the effect of organic products on the yield and quality indicators of chickpeas in the continental climate of the Kostanay Region, Republic of Kazakhstan. In this study, the chickpea (Cicer arietinum L.) cultivar Yubileinyi, sown with four variants, used various biological preparations and a control (pure sowing). The plant samples’ analysis ensued in the laboratory of the State Institution Republican Scientific and Methodological Center of Agrochemical Service, with the field experiments established in the Zarechnoye Agricultural Experimental Station Limited Liability Partnership. The object of the study was the cultivar. During the probe period, the experimental site climate had a continental characteristic, meteorological conditions were arid, and the hydrothermal coefficient was 1.0. Based on various experiment variants and the biological preparations, chickpea grain yield ranged from 8,740 to 13,699 kg ha-1 compared with the control treatment (7,980 kg ha-1). The chickpea’s quality indicators also showed improvements, and the grains harvested from one hectare contained 245.6 kg of protein and 62.4 kg of carbohydrates. The significant yield improvement in chickpeas was due to increased organic active substances in the different preparations used during the study.

The biological preparations, viz., Baikal EM-1 and Rizovit AKS, compared with the mineral fertilizer (double superphosphate), significantly enhanced the growth and yield traits of the chickpea crop.
