The conducted research is devoted to the selection of the optimal assortment for certain growing conditions and preparations for seed treatment before sowing during the growing season, which is one of the important tasks not only to increase the level of yield and productivity elements, but also to obtain normally developed seedlings in order to improve the sowing qualities of seeds of agricultural crops, including chickpeas. It was established that the use of biological preparations for the pre-sowing treatment of common chickpea seeds, namely inoculants and retardants during the growing season, makes it possible to reasonably approach the planning of agrotechnical cultivation measures on the basis of soil conservation in conditions of climate change. The main goal of the study is to study the patterns of manifestation and formation of elements of productivity and yield level of common chickpea plants depending on the varietal composition, seed inoculation and retardant concentration. A three-factor experiment was established in the conditions of the Vinnytsia region (Right-Bank Forest-Steppe of Ukraine) during 2018–2022. The research material was chickpea varieties of domestic breeding — Skarb and Pegas, which were studied according to the following experimental scheme: control (without treatment), seed inoculation (treatment of seed material with the biological preparation Rizugumin-Plus), concentration of retardant (without treatment, 0,5%, 0,75% and 1,0% solution). Variants of the experiment were placed by a randomized method in four repetitions. Field and laboratory studies were conducted on the following indicators: yield, fat and crude protein content according to generally accepted methods. Based on the manifestation of the studied signs, the variant with seed treatment with the drug Rhyzogumin-Plus and two-time treatment of the crops with the chlormequat-chloride retardant was selected: the first — in the phase of the 3rd trifoliate leaf, the second — in the budding phase. The best varieties in terms of performance elements of common chickpea were noted. Statistical processing of yield data according to experiment options was carried out using variance analysis. The share of influence of variety factors, seed treatment and retardant concentration on the yield level was determined.
