Effectiveness of polyfunctional microbial preparations in growing Pisum sativum L. in the South of Russia

Abstract

The possibility of obtaining high yields of pea (Pisum sativum L.) with bacterial pre-sowing treatment without the use of mineral fertilizers in the steppe zone of the Crimea was shown. Effectiveness of microbial preparations in unfavorable climatic conditions in 2015, 2017 and favorable conditions in 2016 in the steppe zone of the Crimea was determined. On average, for 2015-2017, the use of pre-sowing treatment with Cyano-rhizobial consortium was provided a significant increase in 1000 seeds weight by 18.92 g (8.7%) compared to the variant with a mineral fertilizer Amophos (Duncan’s test, p = 0.000053). Application of polyfunctional complex Rhizobofit + Phosfoenterin + Biopolicyd and Cyano-rhizobial consortium contributed to a significant increase in seed yield by 0.14-0.16 t/ha (5.47-6.257%) compared to a mineral fertilizer Amophos (Duncan’s test, p = 0.000077; p = 0.000226). These preparations are recommended for growing pea in the steppe zone of the Crimea.
