Ameriolations with VAM and PSB Inoculation of Growth and yield attributes in Pea (Pisum sativum L.) cv. Arkel

Abstract

Background: Pea (Pisum sativum L.) is one of the most important legume grown all over the world with its varied uses as vegetables and other processed products. Its production and productivity in recent times have witnessed a diminishing graph due to numerous biotic and abiotic stresses. With unexploited use of synthetics in legume crops number of nodule formation have reduced to lowest levels. VAM (Vesicular Arbuscular Mycorrhiza) and PSB (Phosphate Solubilizing Bacteria) inoculation in soil have been observed in enhancing number of nodules, levels of NPK uptake and yield in pea. Methods: Considering the importance of above facts and experiment was laid in 2022 with RBD with three replications containing 7 treatments viz. T1 (Control), T2 (75% RDF + 25% PSB), T3 (50% RDF + 50% PSB), T4 (75% RDF + 25% VAM), T5 (50% RDF + 50% VAM), T6 (75% RDF + 12.5% VAM + 12.5% PSB) and T7 (50% RDF + 25% VAM + 25% PSB). Result: Investigations indicated that the treatment T7 (50% RDF + 25 % VAM + 25% PSB) showed significantly high growth, yield and quality like plant height (113.90 cm), number of leaves (87.09), number of branches (20.2), number of nodules (90.56), numbers of pod/plant (19.1), pod length (8.97 cm), number of seeds per pod (8.23), green pod yield/plot (4.80 kg), green pod yield/ha (80.12 q) compared to control. Hence, T7 (50% RDF + 25% VAM + 25% PSB) evidently exhibited a conglomeration of bio nutrient uptake enhancers resulting in maximum yield and quality.
