Response of Wheat to Different Levels of Phosphorus and Zinc

Phosphorus and Zn deficiencies are common nutritional restrictions to crop production in the soils of Pakistan. The P-Zn interactions in plants have been examined in the past but their interaction effects on economic yield of crops are still confusing, particularly in sandy clay loam soils. For these reasons, a field experiment was laid out in RCBD-factorial with three replications. It is concluded from this experiment that the treatment with 40 kg P and 8 kg Zn ha-1 gave the best combination of phosphorus and zinc levels at 100 kg N ha-1. It is also the most suitable from economic point of view as it gave maximum benefit cost ratio and value cost ratio along with high net income.
