The study looked at how adding phosphorus, sulphur, and phosphate solubilizing bacteria affected the growth and nutrient uptake of mustard plants in sandy soil. They found that increasing phosphorus levels improved crop growth and nutrient uptake. Adding sulphur also boosted growth, yield, and nutrient uptake. Using phosphate solubilizing bacteria increased yield, nutrient content in seeds and straw, and soil nutrient availability. The best results were seen when combining 50 kg of phosphorus, 40 kg of sulphur, and seed inoculation with phosphate solubilizing bacteria.
