Influence of Drip Fertigation Levels on Physiological Parameters of Aerobic Rice in Western Zone of Tamil Nadu, India

Type: article
Abstract: A field experiment was conducted during kharif 2016 at R&D farm of Jain Irrigation Systems Ltd., Udumalpet with seven treatments comprising of two irrigation (100% and 150% ETc) and three fertigation levels (75%, 100% and 125% RDF) in addition, surface irrigation method as a check were arranged in randomized block design and replicated thrice. Rice was grown in sandy clay soil with pH and EC of 7.6 and 0.21 (dS m-1), respectively. A 115 day long variety ADT (R) 45 was used with spacing of 20x10cm. Fertilizers were applied @ 150:50:50 kg of N P2O5 K2O ha-1. The result indicated that surface irrigation method resulted in higher grain yields and physiological parameters except root length as it was higher with lower water and higher fertilizer level (75% ETc + 125% RDF). Within the aerobic rice treatments, drip fertigation at 150% ETc with 125% RDF recorded higher grain yields and physiological parameters and it was found to be on par with surface irrigation method.
