Abstract
A field experiment was conducted in the rabi (dry) season of 1998–99 on a clay terrace soil of Bangladesh, in order to study the effects of irrigation and potassium (K) fertilization on the yield, total water use, and water use efficiency of radish. Both irrigation and K application were found to be indispensable for increasing the yield of radish, due to their individually significant impact on the yield. The interaction effect of irrigation and K application was insignificant, but the highest yield of 30.1 Mg ha−1 was obtained under the highest levels of irrigation and K application (four irrigations with 160 kg K2O ha−1) as the positive effects of both treatments on the radish yield. From the economic viewpoint, the yield of 29.9 Mg ha−1 under four irrigation levels with 120 kg K2O ha−1 gave the highest net benefit. The total water use in this case was 101 mm, having the water use efficiency 297 kg ha−1 mm−1. Based on the acceptable economic yield, high water use efficiency, and the maintenance of proper soil fertility, four irrigation levels and K application at the level of 120 kg K2O ha−1 proved to be the best combination for the sustainable radish cultivation in Shallow Red–Brown Terrace Soil of Bangladesh.
