Symbiotic Effectiveness of Acid Tolerant Nodulating Rhizobia on Growth, Yield and Nutrient Uptake of Pigeon pea (Cajanus cajan L.) in Acidic Alfisols

The symbiotic association between root nodulating bacteria viz. Rhizobium and pulses enhance the crop agronomic characteristics, productivity quality depending upon effectiveness of bacterial strain. To evaluate this effectiveness, a study was conducted during December, 2019?April, 2020 (rabi) at Central Farm Odisha University Agriculture Technology, Bhubaneswar- 751003, aimed evaluating efficiency seven isolated rhizobial strains pigeon pea BRP-2, BRP-4, BRP-8, BRP-20, BRP-28, BRP-56 local strain CHRS-7 in randomized block design with four replications. cv PRG-176 used for study. results revealed that seed inoculation different enhanced plant height (41.84–90.09 cm), relative growth rate (0.410?0.898 mm day-1), nodular nitrogen (3.11 to 4.11%), pod characteristics pea. In addition potentiality producing only 408 kg ha-1 without any could be produce 888 by coastal agroecosystem. findings also better uptake nutrients inoculated practices performed order Control <BRP-20<BRP-8<BRP-4<BRP-56<BRP-28<BRP-2<CHRS-7. performance (CHRS-7) over other it gives cardinal importance enhancement growth, economics acidic Alfisols.
