    Plant growth promoting bacteria (PGPB) enhance crop productivity as part of green technology to reduce the use of chemical fertilizers. They also have the capability to enhance macro- and micronutrient content of plants. In the present study, PGPB isolates belonging to Pseudomonas citronellis (PC), Pseudomonas sp. RA6, Serratia sp. S2, Serratia marcescens CDP13, and Frateuria aurantia (Symbion-K) were tested on two chickpea varieties, PBG1 and PBG5 grown for 30 days in local soil from Bathinda region in Northwestern India. PC and CDP13 were found to be better chickpea growth stimulators compared to the commercial Symbion-K based on shoot length and biomass. Most PGPB enhanced macro- and micronutrients in shoots to varying degrees compared to the control. PBG5 gave better response compared to PBG1 with reference to plant growth attributes and enhancement of the macronutrients, calcium, nitrogen and phosphorus and micronutrients, boron, copper, iron, and zinc. PBG5 is a high yielding variety with better resistance compared to PBG1. Overall, PGPB isolated from the local soil and PGPB from other parts of India were shown to be useful for enhancement of nutrient content and plant growth.

    Nutrient Analysis of Two Chickpea Cultivars Grown in Local Soil and Treated with Plant Growth Promoting Bacteria from Bathinda Region
    (Central University of Punjab, 2018) Dogra, Nitin; Wusirika, Ramakrishna
    The bacteria found near plant roots are known to affect plant and soil health. Several important characteristics, such as biological nitrogen fixation, phosphate solubilization and production of siderophores and phytohormones are together called plant growth promoting (PGP) traits. In the current study, the plant growth promoting activity of five bacterial strains, Pseudomonas citronellis (PC), Pseudomonas sp. RA6, S2, Serratia marcescens CDP-13 and Symbion-K (Frateuria aurantia) were observed on chickpea varieties PBG1 and PBG5, grown in pots containing soil collected from Central University of Punjab city campus. The plants were harvested after 30 days and shoot length, root length, plant biomass and nutrient content of shoots were evaluated.
