A field experiment was conducted in 2014 and 2015 during kharif at Zonal Agricultural and Horticultural Research Station, Navile, Shivamogga under rainfed situation to standardize the foliar nutrition in maize. Three fertilizer levels viz., 100 %, 80 % and 60 % of RDF are assigned to main plot and eight foliar fertilization schedules viz., S1- Foliar application of 19:19:19 at 20 days after sowing, S2- Foliar application of 19:19:19 at 40 days after sowing, S3- Foliar application of 19:19:19 at 60 days after sowing, S4- Foliar application of 19:19:19 at 20 and 40 days after sowing, S5- Foliar application of 19:19:19 at 20 and 60 days after sowing, S6- Foliar application of 19:19:19 at 40 and 60 days after sowing, S7- Foliar application of 19:19:19 at 20, 40 and 60 days after sowing, S8- Control, were assigned to sub-plot. Among fertilizer levels significantly higher grain yield (7007 kg ha-1), stover yield (9003 kg ha-1), gross returns (Rs. 92736 ha-1), net returns (Rs. 56637 ha-1) and benefit: cost ratio (2.56) were recorded with 100 per cent RDF. Among foliar fertilization treatments foliar fertilization of 19:19:19 at 1 % concentration at 20+40+60 DAS has recorded significantly higher grain yield (7087 kg ha-1), stover yield (8866 kg ha-1), gross returns (Rs. 93491 ha-1), net returns (Rs. 57658 ha-1) and benefit: cost ratio (2.60). Interactive effects of fertilizer levels and foliar fertilization revealed that, combination of 100 per cent RDF along with foliar fertilization at 20+40+60 DAS has recorded higher grain yield (7530 kg ha-1) stover yield (9315 kg ha-1) gross returns (Rs. 99144 ha-1) and net returns (Rs. 61708 ha-1). However, benefit cost ratio was highest (2.66) with application of 80 per cent RDF along with foliar fertilization at 20+40+60 DAS.
