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.
