EFFECTIVENESS OF HERBICIDES ON CHICKPEA CROPS

Abstract

According to the results of a study conducted in 2018 and 2019 at the experimental sites of «Kamenka and D» LLP in the Sandyktau district of Akmola region, the most common types of weeds in economic conditions were representatives of cereals. In the conditions of the farm when growing chickpeas, the most common weeds were plants-representatives of the bluegrass family (monocotyledons). According to the results of field experiments, the high efficiency of the studied herbicides was established, however, the highest biological, economic and economic efficiency was shown by the herbicide Fusilade Forte 150 K.C. (fluazifop-P-butyl 150 g/l) consumption rate - 0.75 l/ha. At the same time, the biological efficiency before harvest was 92.9-90.8%, and the economic efficiency was 33.3-26.2%. This was 5.0-8.1% and 4.4-8.3% higher than in other variants, respectively. In 2019, the level of profitability was significantly higher than in 2018 (173.8-265.4%), which, in addition to the impact of the studied herbicides, was affected by weather conditions during the growing season of the crop, especially the positive temperature during the formation and maturation of seeds.
