FORMATION OF PRODUCTIVITY AND GRAIN QUALITY OF PEAS DEPENDING ON PLANT GROWTH REGULATOR.

The formation of high and stable yields is the main value of sowing peas (Pisum sativum L.) as a leguminous crop. The aim of the research was to study the influence of plant growth regulators on the processes of growth and development, formation of productivity, and grain quality of peas. The study of the influence of plant growth regulators on the productivity and quality indicators of peas was conducted according to the following scheme: control (without treatment with preparations), at the budding stage treatment with Humifield VR-18 w.s. (0.4 L ha-1), at the pod formation stage treatment with Fulvigrin Bor (0.5 L ha-1), at the budding stage treatment with Humifield VR-18 w.s. (0.4 L ha-1) + at the pod formation stage treatment with Fulvigrin Bor (0.5 L ha-1). The maximum yield was obtained in the variant with treatment of pea plants at the budding stage with Humifield VR-18 + at the pod formation stage with Fulvigrin Bor, amounting to 3.81 t.ha-1. According to the research results, the highest protein content was obtained from treatment at the budding stage with Humifield VR-18 + at the pod formation stage with Fulvigrin Bor - 23.2%. Based on the research results, it was established that to obtain a pea yield of 3.81 t.ha-1 with a protein content of 23.2%, it is proposed to use plant growth regulators at the budding stage with Humifield VR-18 + at the pod formation stage with Fulvigrin Bor.
