Abstract
A 2024 field study at Vivekananda Global University, Jaipur, evaluated phosphorus management in mungbean on loamy sand soil using a randomized block design with 12 treatments, including Phosphate Rich Organic Manure (PROM), Phosphate Solubilizing Bacteria (PSB), Vesicular Arbuscular Mycorrhiza (VAM), Pseudomonas Fluorescens (PF), and their combinations. The mungbean variety IPM-02-3 showed enhanced growth and yield parameters with PROM and microbial inoculants. The combination of PROM + PSB + VAM + PF (T12) yielded the highest grain (1339 kg/ha), straw (2702 kg/ha), and biological yields (4041 kg/ha), up 58.7%, 65.7%, and 63.2% over the control, respectively, and was comparable to PROM + PSB + VAM (T9). Economically, T12 gave the highest net returns (Rs. 82,378/ha), while T9 was similarly profitable. PSB alone had the highest benefit-cost ratio (1.68). Both T12 and T9 improved post-harvest soil N and P availability. Although T12 recorded the highest grain yield (1339 kg ha⁻¹) and net returns (Rs. 82,378 ha⁻¹), T9 (PROM + PSB + VAM) produced statistically comparable grain yield (1297 kg ha⁻¹) and economic returns. Therefore, T9 may be considered a cost-effective alternative where additional inoculation with Pseudomonas fluorescens is not economically justified.
