A study was done to see how different bacteria and levels of salt and phosphate fertilizer affect the growth of corn plants. The researchers found that using a mix of phosphate soluble bacteria, Azotobacter, and Pseudomonas fluorescens bacteria helped the plants grow taller, produce more grain, and have higher nutrient levels. This mix was better than using just one type of bacteria. Also, plants treated with higher levels of phosphate fertilizer and lower salt levels had better growth and yield. Overall, the combination of these factors led to significant improvements in plant height, grain yield, and nutrient content compared to untreated plants.
