Abstract: Field experiment was conducted during kharif 2017 at Soil and Water Management Research Institute, Kattuthottam, Thanjavur with the objectives of studying the effect of varied irrigation and nutrient regimes on the physiological and yield parameters of groundnut grown in sandy loam soils of Cauvery command. Ten treatments comprising of three irrigation regimes (75%, 100% and 125% PE) with three fertigation levels (75%, 100% and 125% RDF) were tested. The surface irrigation method with soil application of 100% RDF was included as check. The results revealed that drip fertigation at 125% PE with 125% RDF recorded higher plant height (52.2cm), leaf area index (3.47), dry matter production (7848 kg ha-1), pod yield(3636 kg ha-1) and haulm yield (6690 kg ha-1) resulting in a yield increment of 45% over surface irrigation with soil application of 100% RDF. However, the above fertigation treatment was found to be on a par with drip fertigation at 125% PE with100% RDF in groundnut.
