Abstract

One of the promising areas in agriculture is the use of intensive technologies, which include the use of bioregulators and micronutrient fertilizers. These technologies are widely used in the cultivation of leguminous crops, particularly lentils, which are an important component of dietary and functional nutrition. The aim of this study was to evaluate the effect of certain bioregulators and micronutrient fertilizers on the yield and seed quality of the new winter lentil variety Erebuni. Over the course of three years of research, the preparations Epin-Extra, Zircon, and Humate+7 microelements were tested, with quadruplicate experiments. An evaluation was conducted on the effects of Epin-Extra, Zircon, and Humate+7 microelements on the yield of Erebuni winter lentils during pre-sowing seed treatment and foliar treatment of vegetative plants at the budding-flowering stage. It was shown that both a single foliar treatment of vegetative plants and a double treatment (seeds and vegetative plants) resulted in a significant yield increase compared to the control (0.46–1.02 t/ha). A slight decrease (0.4-2%) in crude protein content in seeds compared to the control is offset by an increase in crude protein yield per hectare compared to the control (8.7-12.2% with foliar treatment of vegetative plants only and 26.6-52.6% with dual treatment (seeds and vegetative plants). The research results showed that these preparations, which are low in cost and require small application rates, can be recommended to agricultural farms for increasing lentil productivity under the conditions of Armenia.
