Abstract :The yield parameters and cost economics of Withania somnifera were studied using dual inoculation of Azotobacter chroococcum and Pseudomonas putida. The experiment was conducted in a randomized block design with 3 replications for 2 consecutive years, along with 2 levels of organic manure, 10 t ha-1 and 20 t ha-1. Inoculation with the inoculants generated encouraging results; root yield insert ignore into journalissuearticles values(1185.6 kg ha-1);, seed yield insert ignore into journalissuearticles values(208.13 kg ha-1);, number of offshoots per plant insert ignore into journalissuearticles values(6.07);, and plant height insert ignore into journalissuearticles values(108.4 cm); were maximum with treatment T6 insert ignore into journalissuearticles values(organic manure [OM] 20 t ha-1 + both bacteria);, followed by T9 insert ignore into journalissuearticles values(OM 10 t ha-1 + both bacteria);, T4 insert ignore into journalissuearticles values(OM 20 t ha-1 + A. chroococcum);, and T5 insert ignore into journalissuearticles values(OM 20 t ha-1 + P. putida);, as compared to T1 insert ignore into journalissuearticles values(control);, T2 insert ignore into journalissuearticles values(OM 10 t ha-1);, and T3 insert ignore into journalissuearticles values(OM 20 t ha-1);. The survival count of inoculated bacteria was highest 70 days after inoculation and declined thereafter. Economic analysis revealed that the net profit from treatment T6 was the highest with dual inoculation of bacteria and OM 20 t ha-1, followed by OM 10 t ha-1 and dual inoculation of bacteria.
