We studied the use of the complex microbial preparation (CMP) in 2016-2018 at the experimental field of the Research Institute of Agriculture of Crimea. The soil is southern chernozem. Long-term annual precipitation – 428 mm; long-term annual air temperature – 12 °С. Pisum sativum L. variety – ‘Madonna’. Chemical treating agent Vitavax 200 FF (water suspension concentrate) at the rate of 0.75 l/ha was used in the control variant. Seeds were inoculated with CMP on the day of planting (FSBSI “Research Institute of Agriculture of Crimea” is the owner of CMP). The composition of the studied complex – 1) symbiotic nitrogen fixers; 2) phosphorus mobilizing microorganisms; 3) microorganisms that inhibit the growth and development of phytopathogenic bacteria and fungi. On average, over three years of research, the height of pea plants was the same and amounted to 82.3 cm in the control and 80.7 cm in the experimental variant. The symbiosis of PS and CMP had a significant effect on the number of beans per plant. In the control, 7.6 pieces were formed; under the influence of CMP – 8.6. In our experiments, the grain size was influenced both by the conditions of the growing season in a particular year and the treatment with CMP. The most favorable conditions were in 2016, which contributed to the largest 1000-grain weight (on average 284 g). In extremely arid 2018, the smallest peas were formed (1000-grain weight – 258 g). On average for 2016-2018, the yield in the variant with inoculation was 0.2 t/ha higher. The small Pisum sativum L. yield in 2018 can be explained by the low air humidity and the absence of productive precipitation.
