Abstract

The article is devoted to the study of the influence of sowing methods, seeding rate and herbicide on the development, yield and photosynthetic activity of chickpea sowing – one of the most controversial issues in chickpea agricultural technology. The influence of sowing methods and seeding rates on the photosynthetic activity of plants has been studied. The selection of effective measures to control chickpea weeds is also part of our research. One of the most significant issues for obtaining high yields of chickpea is the correct sowing method, seeding rate and the use of herbicides. The studies were carried out in 2017–2018. on the experimental field of the North Caucasus Research Institute of Mining and Piedmont Agriculture of the All-Russian Scientific Center of the Russian Academy of Sciences on leached chernozems: arable layer pH salt. 5.8–6, humus content 5.8%, easily hydrolyzable nitrogen – 80 mg/kg, available phosphorus – 118 mg/kg, exchangeable potassium – 120 mg/kg, molybdenum – 0.25 mg/kg, boron – 0,5 mg/kg of soil. In field experiments, the seeding rates, the method of seeding and the effect of herbicides were studied. The aim of the research was: to develop agricultural practices that ensure the collection of grain products and vegetable protein in the foothill zone of RNO-Alania. According to the results of the studies, in the conditions of the foothill zone of the Republic of North Ossetia – Alania, according to the complex of indicators of plant activity, variants were distinguished when applying the herbicide with seeding rates of 0.8 and 1.0 million viable seeds per hectare with a wide-row sowing method and with seeding rates 0.6–0.8 million germinable seeds per hectare with the drill method. Against a herbicide-free background, the best options were with a seeding rate of 1.0 million viable seeds per hectare, both with wide-row and with a row sowing method.
