Abstract

A field experiments was carried out during summer 1996 and 1997 at Vamban to study the productivity of irrigated Groundnut (Arachis hypogaea L.) as influenced by land management using organic amendments under varying irrigation regimes. Adopting land management of ridges and furrows and providing irrigation at 0.8 IW/CPE resulted in higher groundnut pod yield of 1588 kg/ha and benefit cost ratio of Rs. 2.75 under red lateritic soils of Vamban. Application of enriched FYM registered significant increase in plant height, number of pods per plant. pod yield WUE and benefit cost ratio over bio- digested slurry and pressmud in both the years.
