Abstract: A study was undertaken to know the effect of graded levels of nutrients and irrigation methods on nutrient content and uptake of aerobic rice at V. C. Farm, Mandya, Karnataka during 2016-17 and 2017-18. The pooled data on grain yield of aerobic rice indicated that drip fertigation with 125 per cent N, P and K of RDF through WSF recorded higher grain yield in pooled analysis (6675 kg ha^-1) and similar trend in first and second season which was on par with drip fertigation of RDF with 100 per cent WSF (5969 kg ha^-1) in pooled data. The same treatment recorded higher straw yield in pooled analysis (8158 kg ha^-1) and similar trend in first and second season. Significantly higher content and uptake of primary and secondary nutrients of aerobic rice during first season, second season and pooled data was registered in the same treatment and was followed by T₆ that received 100 % N, P and K of RDF through WSF.
