Field experiments conducted at the Agricultural college and Research Institute Farm, Tamil Nadu Agricultural University, Coimbatore during monsoon 1990 and summer 1991 to study the irrigation management practices on groundnut with special reference to irrigation field layouts and soil amendments revealed that irrigating groundnut at 0.75 IW/CPE ratio with ridges and furrows and coir waste at 15 tha resulted higher productivity, net return and benefit: cost ratio under adequate water supply. Under water scarcity conditions irrigation even at 0.5 and 0.6 IW/CPE ratio with flat ridges and furrows with 10-15 tha of coir waste recorded higher water use efficiency without appreciable reduction in groundnut pod yield.
