The study aimed to see how well a type of bacteria called Pseudomonas fluorescens can survive on different materials like nanoprosil-1 and vermicompost, and how they affect the growth and yield of maize plants. The researchers tested different combinations of these materials and found that using Pseudomonas fluorescens with vermicompost or a mix of vermicompost and nanoprosil-1 helped maize plants grow better and take up more phosphorus from the soil. This could be a good way to improve maize crop production.
