The analysis of literary sources showed that interest in chickpeas is increasing, sown areas under this crop are expanding, and technological features for chickpea cultivation are changing. The yield of chickpea seeds to a large extent depends on the biological characteristics of the variety, fertilizers, compliance with the timing and methods of sowing, inoculation of seeds and the like. Much attention should be paid to the system of protection of chickpea agrocenoses from harmful organisms. Weak competition of chickpea plants with weeds is primarily due to the peculiarity of the development of this culture in the early stages, when there is an intensive development of the root system and slow - the aboveground part. In these early stages of their development, chickpea plants are not yet able to fully compete with weeds. The latter, on the contrary, are serious competitors, as they actively use nutrients, moisture and shade plants. High selectivity and herbicidal activity in chickpea crops were shown by soil preparations: Stomp, 33% k.e. (4.0 l / ha); Harness, 90% (1.5–3.0 l / ha); Optima frontier (0.8– 1.0 l / ha). Weed reduction was 85–90% and yield increase was 0.71–0.82 t / ha. Of the post-emergence herbicides in chickpea crops in conditions of mixed weed type, it was advisable to use Pulsar (0.5-0.9 l / ha) and Pivot (0.5-0.8 l / ha). Weed loss was 81.0–82.0% and yield increase was 0.72–0.76 t / ha. When using different herbicides, the yield of chickpea grain was in the range from 1.26 to 1.44 t / ha. The presence of chickpeas in crops leads to severe inhibition, especially in the initial stages of vegetation. The most effective and economically feasible at present is the use of a tank mixture of herbicides Harnes + Gezagard 500 FM (2.0 l/ha + 3.0-4.0 l/ha) which makes it possible to control a wide range of weeds and extend the duration of the protective shield preparations. Chickpea seeds ripen fairly evenly throughout the plant, the beans do not crack or crumble, the plants do not lie down, so when harvested by direct combining there are no problems. The growing season in chickpeas lasts 80-120 days, depending on the variety and growing conditions, so it is harvested in late July or early August after harvesting cereals. The yield of chickpea seeds varies in the range 1.4–2.7 t/ha, and with proper technology and climatic conditions it can be 2.5–3.5 t/ha.

Nowadays no herbicide has been approved for use on chickpea crops has been officially registered in Ukraine. Weed control measures are mainly used. However, many years of experience in the use of a number of herbicides in our country and in other countries. In this regard, the effectiveness and selectivity of soil preparations such as Harnes, 90% k.e., and Frontier Optima, 72% k.e. were studied in chickpea crops. These herbicides were applied after sowing chickpeas until the emergence of seedlings. Application of Harness herbicide, 90% k.e., at a rate of 3.0 l / ha in the soil before the emergence of chickpea seedlings leads to a decrease in weed vegetation a month after application of the herbicide to 88% compared to control areas where measures to protect against storms vegetation was not carried out. The regulation of the number of weeds and their harmful effects in chickpea agrophytocenoses to an economically harmless level is an important condition in the technology of its cultivation. The most relevant weed control is at the beginning of the growing season of the crop, since this the chickpea grows very slowly, is in the rosette phase for a long time, and therefore does not withstand competition from weeds. To increase the yield of chickpea seeds, an important place in the technology of growing crops is the use of herbicides and biological products. Inoculation of chickpea seeds with Rizobofitt at a consumption rate of 1 l / t and with a biofungicidal preparation Biopolycide at a consumption rate of 100 ml/t, by introducing a soil herbicide Frontier Optima, 72% k.e., at a consumption rate of 1,2 l/ha, contribute to the reduction of weeds to 91%, and the ability to obtain the yield of chickpea seeds at the level of 2,12 t/ha.

Chickpeas are a high-tech legume crop, so the improvement of scientifically sound technology of chickpea cultivation is a priority among agricultural producers. The article presents the results of the study of the effect of soil herbicides, the microbial preparation Rhizobophyte and the biofungicide preparation Biopolicide on the growth, development and productivity of chickpea plants. There is a clear dependence and positive effect of microbial preparations on the height of chickpea plants, grain yield of chickpea varieties Triumph and Rosanna when used in combination with herbicides. When combined before sowing chickpea seeds with the microbial drug Rhizobophyte (1,0 l/t) and biofungicide Biopolicide (100 ml/t) and application of this background soil herbicide Frontier Optima, 72% k.e., at the rate of 1,2 l/ha contribute to the control of weeds in chickpea crops, intensive growth and development of cultivated plants in height, a significant increase in the yield of chickpea seeds. In particular, the height of the plants of chickpea variety Rosanna in the phase of full flowering on average over the years of research was within 59.4 cm, and the increase before control was 23,6 cm. The number of beans formed per plant was within 19,41 pieces. The yield of chickpeas of Rosanna variety in these areas was within 2,28 t/ha, the increase before control was 1,74 t/ha or 322%. Thus, the effectiveness of the basic physiological and biochemical processes of the phases of growth and development of chickpea plants depends on a number of elements: agronomic, seed inoculation, the use of chemical and biological pesticides. The yield of chickpea seeds depends on the control of weeds in its crops, in particular, the application of the soil herbicide Frontier Optima, 72% of the active ingredient, at the consumption rate of 1.2 l/ha, as well as the complex pre-sowing treatment of chickpea seeds with the biological preparation Rhizobophyt, 1.0 l/t + biofungicidal drug Biopolicid, 100 ml/t. These measures contribute to the yield of Rosanna chickpea seeds at the level of 2.28 t/ha.

The yield of chickpea seeds depends on the biological characteristics of the variety and the cultivation technology. Increasing the effectiveness of the factors for the intensification of chickpea cultivation should be carried out on the basis of modern requirements. For the cultivation of chickpeas, the duration of the growing season is important, since the growth, development and formation of the harvest of this crop can last from 60 to 130 days. The duration of the growing season is influenced by the genetic characteristics of the variety, the soil and climatic conditions of the region, and the use of certain elements of growing technology. Studying the rates of growth and development of chickpea plants in ontogeny makes it possible to reveal the most important dependencies of the process of formation of high productivity of this crop. In the conditions of the Right Bank Forest-Steppe, the difference between the varieties in the time of interphase periods was insignificant and was 2–3 days, so the duration of the growing season in the Triumph variety was 97 days, and in the Rosanna variety - 100 days. In the intensive technology of growing chickpeas, the use of soil herbicides is a mandatory measure. Treatment of chickpea seeds with biological preparations before sowing and application of soil herbicides affected the growth and development phases of chickpea plants. The duration of the ripening phase of chickpea varieties depended on the treatment of seeds with biological preparations and the level of weediness of these areas. It was established that the duration of the growing season depends on the genetic characteristics of the variety and the elements of the growing technology. The duration of the growing season in the Triumph variety was 103-104 days and in the Rosanna variety - 105-106 days. Treatment of chickpea seeds with Rhizobophyt inoculant and biofungicidal drug Biopolicid and application of soil herbicide Frontier Optima, 72% er, at the rate of 1.2 l/ha helped to obtain the yield of chickpea seeds of the Triumf variety within 2.20 t/ha, which by 1.67 t/ha higher compared to the level of productivity on the weedy control. The yield of Razanna chickpea seeds was correspondingly higher and amounted to 2.28 t/ha, which is 1.73 t/ha more than in the control plots.
