Abstract

A field study was conducted at Tamil Nadu Agricultural University, Coimbatore during rabi season of 2019-20 to study about the growth and yield of aerobic rice under different drip fertigation and irrigation levels. Thirteen treatments consists of 75 % and 100 % pan evaporation (two irrigation levels) and 75%, 100% and 125% RDF (three fertigation levels), combination with fermented fish waste (FFW) and fermented egg product (FEP), surface irrigation treatment as a check were arranged in randomized block design and replicated thrice. The result showed that significantly higher plant growth, yield attributes and yield during rabi season 2019 – 20 were observed in drip fertigation at 125 % RDF, 100 % PE with FFW (3 times) than all other treatments. Which was closely related with drip fertigation at 125 % RDF, 100 % PE with FEP (3 times). The lower growth and yield were noticed in drip fertigation at 75 % RDF, 75 % PE with FEP (3 times). This study concluded that drip fertigation at 125
