Abstract
The study aimed to assess the impact of plant growth promoting rhizobacteria capsules on the growth and yield of ginger. PGPRs known for their role in nitrogen fixation, phosphate solubilization, and hormone secretion. These PGPR’s tested at the Turmeric Research Station, Kammarpally across three consecutive years (2018-2021) in combination with three ginger varieties (Mahima, Maran, Local type) and five different treatments T1-POP + Trichoderma (Talc formulations) + GRB 35 (Talc formulations), T2- POP + Trichoderma capsules + GRB 35 capsule, T3- POP + Trichoderma capsules, T4- POP + GRB 35 capsule, T5- POP (Recommended package of practices). The treatment T4V1 (POP + GRB 35 capsule with Mahima variety), produced the highest fresh rhizome yield with 6.28 kg plot-1 and 21.53 t ha-1 followed by T4V2 (POP + GRB 35 capsule with Maran variety) at 6.16 kg plot-1 and 20.15 t ha-1. These results suggest that GRB 35 capsules significantly enhance ginger yield, offering a sustainable approach to ginger cultivation.
