Abstract

Currently, the issue of preserving organic matter, which is increasingly being replaced by synthetic alternatives, is relevant and expedient. But these substitutes are alarming because of their possible threat of dangerous after-effects, because the human body generally consists of what it consumes in everyday food. All chemical elements undesirable for the body that can cause the appearance of diseases and health complications fall under the category of dangerous food. In view of this, in order to preserve the volume of production of natural food products, there is a need to increase the share of leguminous crops. In addition to the positive effect on soil fertility, legumes are naturally filled with biologically pure nitrogen. Also, this crop has a higher content of valuable plant protein compared to cereal grain crops. In order to increase the production of pea grain, it is necessary to use high-yielding varieties of the moustached morphological type. The purpose of the article is to identify the influence of sowing dates and treatment of vegetable pea seeds with molybdenum and boron fertilizers on plant development indicators in the conditions of Southern Ukraine. The research used the laboratory method, as well as the methods of field experiment and phenological observation. It was established that the effect of boron and molybdenum delays the onset of the phenological phases of crop development, and the use of two different sowing times allows to delay the onset of the technological maturity phase by 6 days. This is important during harvesting for minimal losses of the vegetable pea crop. The practical value of the results lies in the application of combinations of molybdenum and boron fertilizers to increase the yield and nutritional value of leguminous crops
