The present study was conducted in research farm of Department of Genetics and Plant Breeding, Naini Agricultural Institute, Sam Higginbottom University of Agriculture Technology & Sciences, Allahabad (U.P) during Kharif 2017 to investigate the effectiveness various levels of NPK fertilizers, their combinations ( T1 ) 26g Urea: 42g DAP :20g MOP / 2 m2 ( T2 ), 52g Urea: 84g DAP :40 g MOP/ 2 m2 ( T3 ), 78g Urea: 126 g DAP :60g MOP / 2 m2 and delayed sowing on growth and yield characters of three varieties of maize. The three varieties (Kaveri 3110 (V1), Deluxe (V2), Ganga-2 (V3). each were treated with different levels of fertilizers (Urea - 26 g,52g and 78 g) which supplies nitrogen, (DAP- 42g,84g,124g) which supplies nitrogen and phosphorous, (MOP- 20g,40g,60g) which supplies potassium. The experimental design was factorial Randomized Block Design (Factorial RBD) with four replications. The results showed that the treatment combinations V2T2 yielded maximum in all the characters followed by (V1T2) treatment in leaf width, cob length, no of rows/cob, no of grains /row, no of seeds/cob (V3T1) in plant height, no of cobs per plant (V3T2) in tassel length and leaf length (V2T3) in cob diameter and minimum is recorded in control (T0)
