Analysis of biofertilizers activities on growth and biochemical parameters of two varieties, Azad P3 and PB89 of Pea (Pisum sativum)

Abstract

Pisum sativum establish symbiotic relationship with nitrogen-fixing bacteria and fix atmospheric nitrogen in the soil. Plant growth promoting rhizobacteria (PGPR) are a group of soil harbouring large diversity bacteria colonies interact with the plant tissue to provide the growth and development to the plants. Bacteria, Bacillus subtilits and Rhizobium pusense are PGPRs in addition with or without NPK were pre-mixed with soil before sowing the seeds of the varieties, Azad P3 and PB89 of Pisum sativa. The grown pea plants were checked for the root and shoot length, organic content and moisture content, and number of nodules after 30, 45, and 60 DAS. Further, the protein and phenolic contents were estimated in the Azad P3 and PB89 varieties of Pisum sativa. The use of PGPRs increased the overall plant growth and development with or without NPK, although use of the PGPRs increased the plant growth and protein and total phenolic contents. Further, it is important to notice the supplementation of both the bacteria for the growth of the pea plants.
