Abstract
A field experiment on groundnut was conducted during 1992-93 at College of Agricultural Engineering, Kumulur to study the influence of land configuration with irrigation and plant population on water use efficiency. Results revealed that groundnat crop raised in ridges and furrows resulted in higher pod yield and water use efficiency when 4.25 cm of water was applied per irrigation than flat beds applied with 5.0 cm water. Reducing the irrigation water from 4.25 cm to 3.5-cm reduced the yield but the water use efficiency was maintained at a similar level indicating the efficiency of ridges and furrows in conserving applied water.
