A field experiment was conducted during Kharif 2012 at Zonal Agricultural Research Station, Bengaluru in red sandy loam soil (pH-6.9; OC-0.6 %) with medium available nitrogen (348 kg ha-1), phosphorous (36.13 kg ha-1) and potassium (244 kg ha-1) to know the crop performance and economic feasibility of aerobic rice under drip fertigation. The experiment was laid out in Randomized Complete Block Design (RCBD) with 15 treatments. The variety used was MAS 946-1.. The results revealed that drip fertigation at 1.5 PE up to maturity with 100 % RDF through water soluble fertilizers (WSF) registered significantly higher dry matter production (118.40 g hill-1), grain (6598 kg ha-1) and straw yield (11084 kg ha-1) over surface irrigation with soil application of fertilizers (81.30 g hill-1, 3467 and 5995 kg ha-1, respectively). Whereas, drip fertigation at 1.5 PE up to maturity with 100 % RDF through normal fertilizers (NF) recorded higher net returns and B:C ratio (Rs. 72621 ha-1 and 2.88, respectively) and hence found to be economic in rice production under aerobic condition.
