| Abstract | Goal. The article discusses issues related to studying the impact of resource-saving nutrition on the survival and duration of key periods of vegetation in field peas. Peas are a fairly important leguminous crop for human consumption, livestock feed requirements, and soil fertility regeneration. It enriches the soil with valuable organic matter, provides free biological and ecologically clean nitrogen, positively affects the economy of farms, and serves as a good precursor, gaining special significance due to the rising cost of mineral fertilizers and environmental preservation. In light of the above, there is a need to develop elements of resource-saving technology for growing field peas using moderate (starter) doses of fertilizers, biopreparations, and micronutrients that are significantly cheaper than mineral fertilizers, have low application costs, do not harm the environment, and promote enhanced growth processes and plant resilience to adverse factors. The objectives of our research included increasing the productivity of the Madonna variety of field peas through pre-sowing seed treatment, application of N15P15K15 at sowing, and foliar feeding of plants with modern biopreparations and boron at the beginning of budding. Certainly, the course of growth processes and the level of grain yield are significantly influenced by plant survival and the duration of both individual periods and the overall vegetation. This issue is the main focus of this article. The results. Research has shown that seed treatment with Nanovit, application of mineral fertilizer, and foliar feeding of plants increased the survival rate of pea plants from emergence to physiological maturity compared to the control without nutrient optimization. On average over the years of cultivation in all research variants, this indicator increased by 4.6 % for seed treatment with water and by 5.1 % for treatment with Nanovit. Conclusions. It has been determined that the studied factors to some extent influenced the extension of the vegetation period of field peas. This period varied depending on the weather and climatic conditions of the cultivation year, being longest in 2021. | ||
