ABSTRACT
A field experiment was conducted on sandy loam soils, at College of Agriculture, Shivamogga, Karnataka to find out the effect of levels and methods of fertilizer application on growth and yield of aerobic rice during Summer 2016. The experiment was laid out in a Randomized Complete Block Design comprising of 3 replications and 12 treatments. Results showed that aerobic rice yields differed significantly among the treatments. Application of 25% RDF - soil application + 100% RDF - fertigation recorded higher plant height (67 cm), number of tillers plant-1 (39.7), leaf area (2659 cm2 plant-1), leaf area index (4.25), total dry matter accumulation (116 g plant-1), grain yield (71.43 q ha-1) and straw yield (81.72 q ha-1), thereby achieved yield increment of 59 per cent over surface irrigation with soil application of 100 per cent RDF. However, it was found statically on par with 125 or 100 % RDF through fertigation and 25% RDF - soil application + 75% RDF - fertigation treatments.
Key words: Aerobic rice, Fertilizers, summer, Fertigation.
