A field experiment was conducted during winter (rabi) seasons of 2005-06 and 2006-07 to evaluate the performance of different maize cultivars under ridge and furrow method of irrigation and Low Energy Water Application (LEWA) system of irrigation in winter season. The results revealed that among the cultivars 'FH 3352' produced significantly higher grain yield and protein content over all other cultivars in both the years. LEWA irrigated maize produced 6.7 and 10.4% more grain yield and higher water-use efficiency (241.0 and 255.2 kg/ha-cm) over ridge and furrow irrigated maize respectively in both the years. Relative leaf water content was also found significantly higher (89.3 and 91.8%) in LEWA irrigated maize and reverse trend in case of water saturation deficit. It is imperative to say that LEWA system of irrigation is quite efficient for maize crop over ridge and furrow method of irrigation. Among the cultivars, 'FH 3352' a medium duration cultivar can be grown successfully as winter crop in the eastern plains for higher yield.
