Abstract
The effects of irrigation at three soil water potentials under basin and furrow systems of irrigation with different levels of nitrogen were investigated in 1983 and 1984. Frequent irrigations at –20 kPa soil water potential increased relative water content, leaf water potential, osmotic potential, yield, ET and WUE, and decreased canopy temperature as compared to irrigation at –40 and –60 kPa. However, the difference in yield between irrigations at –20 and –40 kPa was not significant. Methods of irrigation had no significant effect on the above parameters although furrow irrigation resulted in a slightly higher WUE. Nitrogen up to 120 kg ha−1 increased turgor potential, yield, ETand WUE.This publication has 2 references indexed in Scilit:
