Enhancing nitrogen-use efficiency, grain yield and protein content in wheat with combined application of novel rock mineral fertiliser and microbial consortium inoculant in sandy soil

Wheat grain yield, protein content and nitrogen-use efficiency are affected by genotype, environment and fertiliser management. Optimising wheat grain yield and protein content requires effective nitrogen fertiliser management and improved nitrogen-use efficiency in sandy soils. The efficacy of biomineral fertiliser containing rock minerals and microbial consortium compared to inorganic fertilisers was examined using different wheat genotypes in nutrient-poor sandy soil. Biomineral fertiliser significantly increased nitrogen-use efficiency, grain yield, and protein content due to increased root growth and enhanced nutrient uptake. Biomineral fertiliser can be a viable alternative to inorganic fertilisers for sustainable wheat production.
