A field experiment was conducted during the rainy (kharif) season of 2000 and 2001 on sandy loam soil at Hisar, to study the response of pearlmillet [Pennisetum glaucum (L.) R. Br. emend. Stuntz] hybrids to nitrogen lev els. Pearlmillet HHB 94 showed significantly higher grain yield (30.74 qlha), higher seasonal water use (273.5 mm) and water use efficiency (1 1.30 kglha mm) than rest of the hybrids. Application of 120 kg Nlha, being at par with 150 kg Nlha, resulted in higher grain yield, water use and water use efficiency than rest of the nitrogen levels. The economic optimum dose of N for HHB 94 , HHB 67, HHB GO , HHB 117 and HHB 146 was 101.5, 105.8, 91 .I, 82.3 and 142.5 kglha respectively.References
