A study was conducted to see how different levels of phosphorus and zinc affect wheat and greengram crops. They found that applying 60 kg of phosphorus per hectare to wheat resulted in the tallest plants and highest test weight. Using 90 kg of phosphorus in wheat led to better growth and yield in greengram. Wheat responded well to 4 kg of zinc per hectare. The residual effect of 6 kg of zinc on greengram after wheat harvest increased yields. Protein content and yield in both crops increased with phosphorus and zinc application. The uptake of phosphorus, zinc, and nitrogen by the crops also improved. Overall, applying 60 kg of phosphorus and 6 kg of zinc in wheat is best for higher productivity and soil health in a wheat-greengram cropping system.
