The researchers studied how adding certain bacteria to the soil can help okra plants grow better. They tested different treatments on okra plants in a greenhouse. The treatments with both Azotobacter and PSB bacteria showed the best results, leading to the highest growth of okra and improving the soil's microbial properties. These treatments also increased the population of beneficial bacteria in the soil and boosted the soil's dehydrogenase activity. Overall, adding Azotobacter and PSB to the soil can help okra plants grow better and improve the soil's health.
