The results of our pervious studies indicated that application of potassium @150 kg K<sub>2</sub>O ha<sup>-1</sup> is effective in achieving economical sugarcane yield and optimum nutrient uptake under saline conditions. Keeping in view these findings, experiments were conducted on salt-affected soils at three sites of Punjab, Pakistan to select a suitable source and rate of N for obtaining optimum sugarcane yield and nutrient uptake from salt-affected soils.
