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.
