The article deals with microbiological fertilizers “Azotovit” and “Fosfatovit” on field pea plants. Seeds were inoculated before sowing to study the effect on the agronomic traits in pea and the seed quality. A significant increase in germination energy (6.1-6.3%) was observed with the combined application of both highly mentioned microbiological fertilizers. Seed germination in the experimental groups ranged from 98.2-99.3%, with 95.4% in the control one for the Fokor variety and 95.7% for the Yubilyar variety. The increase compared to the control options ranged from 2.5 to 3.7%. “Azotovit” and “Fosfatovit” shortened the growing season of pea plants, that made it possible to harvest the pea crops earlier. Pre-sowing fertilization of pea crops improved the yield indicators and increased: the plant height by 5.4-14.3 cm; the length of beans by 0.8-1.2 cm; the number of internodes by 1.0-2.6 pcs.; the number of seeds in the bean by 0.7-10 pcs.; the weight of seeds from one pea plant by 0.1-0.3 g; the weight of 1000 seeds by 10.5-16.4 g and the seed yield by 6.3-12.5 g/l. Combined application of the Azotovit” and “Fosfatovit” microbiological fertilizers significantly increased pea yield by 16.5-24.4% compared to the control.
Keywords: pea, microbiological fertilizers, yield, crop, seed quality.

Potatoes are of great importance for agricultural production in Russia. One of the main reasons for the decline in potato production in the country is the widespread development of fungal and other diseases during the growing season and storage, caused by the lack of varieties with group resistance and a reduction in the scope of protective measures. The gradual increase in certain diseases is significantly influenced by advanced changes in pathogens, along with the changes in their plasticity, adaptability, and pathogenic properties. The research was carried out at the experimental plot of FAT-AGRO LLC in the Prigorodny District of the Republic of North Ossetia-Alania from 2021 to 2023. Having analyzed potato hybrids, a comparative assessment of their quality and resistance to diseases of various etiologies, as well as to adverse abiotic influence in the foothill regions of the North Caucasus were determined.
Keywords: potato, hybrids, variety, potato late blight, virus, alternaria.
