Yield Enhancement of Field Pea (Pisum sativum) through Zinc Solubilizing Microorganism

Abstract

In the rabi season of 2022-223, a field experiment was conducted at Instructional Farm, School of Agriculture, Sanjeev Agrawal Global Educational (SAGE) University Bhopal (Madhya Pradesh) to assess the impact of zinc (zn) and ZSB (Zinc Solubilizing Bacteria) solubilizers on the performance of field pea crops. The results of the experiment revealed that the application of 100% of the recommended dose of fertilizer in combination with zinc led to the highest values in various growth and yield parameters. Specifically, the treatment of 100% Recommended dose fertilizer + Zinc statistically (p<0.05) compared to mean values demonstrated the maximum plant height, dry matter accumulation (in grams), branches per plant, number of pods per plant, number of seeds per pod and seed yield (1060 kg/ha). Additionally, it resulted in a straw of 2130 kg/ha., a biological yield of 4243 kg/ha, a net return of 1639 Rs/ha, and a benefit-to-cost (B: C) ratio of 1.12. It is worth noting that the performance achieved with the application of 100% ZSB was statistically on par with the treatment involving 100% Recommended Dose Fertilizer + Zinc. Overall, all of the treatments applied in the experiment had a significant positive impact on the growth, yield, and economic aspects of field pea cultivation in comparison to the control group.
