Abstract

A field experiment was conducted during the winter season of 1995 96 and 1996 97 on sandy loam soil of Ranchi, to study the production potential and water use efficiency of wheat (Triticum aestivum L. emend. Fiori Paol.) cultivars under different dates of seeding and irrigation level. Yield, yield attributes and water use efficiency of HUW 234 and K 9006 were significantly higher when crop was sown timely on 21 November. The crop which received 4 irrigations showed maximum grain yield and water use efficiency. Both the above cultivars did not show any significant difference in for yield and yield attributing characters, but cultivar HUW 234 showed higher water use efficiency (7.54 kg grainlha mm) than cultivar K 9006 (7.14 kg grainlha mm).
