In the long-term stationary field experiment (part of the Geographic network of fertilizer experiments) on the southern mycelial-calcareous chernozem in the central steppe of the Crimea, we studied the effect of the complex microbial preparation (CMP) on such parameters of Pisum sativum as growth, development, yield and quality. All the surveys were carried out on the fields where a direct seeding was applied. The experiments were conducted in 2016-2019. There were 13.9 seeds per plant in the control variant and 15.1 in the variant with CMP treatment; the increase was 9%. Thus, the weight of grains increased from 39.9 g to 44.1 g or by 10.5%. The use of CMP contributed to the improvement of the biological yield (by 0.37 t/ha). In 2016, pea seed bacterization significantly increased the weight of 1,000 seeds. In subsequent years, it was at the same level as control. Inoculation with the biopreparation in 2016 contributed to the accumulation of higher protein content (by 1.7%) On average, for three years of research, the difference was 0.5% in favor of bacterization. The yield was 0.3 and 0.2 t/ha or 4.9 and 14.0% higher in the variant with CMP in 2016 and 2019 respectively. On average, for three years, inoculation contributed to an increase in yield by 0.1 t/ha.
