Efficiency of phosphate and potassium solubilizing bacteria on growth, yield, essential oil yield, and economics of davana ( Artemisia pallens Wall. ex. DC)

Journal of Plant Nutrition, Journal Year: 2025, Volume and Issue: unknown, P. 1 - 15

Published: March 17, 2025

Sustainable agriculture depends on eco-friendly practices to ensure long-term productivity and environmental well-being. Phosphate potash-solubilizing bacteria enhance nutrient availability, enrich soil health, reduce chemical fertilizer dependency. To evaluate their effectiveness, field experiments were conducted in 2022–23 2023–24 at the CSIR-Central Institute of Medicinal Aromatic Plants Research Center, Bengaluru. The study examined impact Bacillus megaterium Frateuria aurantia agronomic performance use efficiency Artemisia pallens. objective was promote sustainable management while reducing reliance. results experiment state that, statistically superior growth parameters, herbage yield, essential oil yield recorded treatment receiving 100% RDF+PSB+KSB followed by 75% over sole application, RDF, control treatments. Microbial consortia (PSB+KSB) with RDF are more significant improving bacterial population than applications indicating synergism between different species bacteria. Further application combined PSB KSB resulted maximum AUE (Agronomic Use Efficiency) 132.70% a microbial response 35.25%, leading increase 135.25% compared other net returns (US$ 10.81) higher benefit-to-cost ratio 3.95 achieved RDF+PSB+KSB. Overall, incorporating both together is highly beneficial amplify davana crop performance, population, mineralization nutrients demand for fertilizers thereby minimizing hazards.
