A field study was conducted growing maize during monsoon season of 2013 and 2014 to simulate the grain yield under alternative nitrogen fertilization using InfoCrop-maize model. Seven treatments viz. (1) N0 (Control) (2) N120 (3) N140 (NST) (4) 50% urea + 50% FYM (5) 100% FYM (6) Urea + NI and (7) NOCU were tested. Aapplication of urea and NOCU delayed crop phenology while, 50 and 100% substitution of urea by FYM advanced crop phenology. Grain yield among different treatment ranged from 1597-3993 kg ha-1 during first season and 1514-3856 kg ha-1, during second season. Grain yield increased by 0.80 and 0.21% in NOCU and 1.87 and 1.18% in Urea + NI, however it was reduced by 13.6 and 12.0% in 50% urea + 50% FYM and 46.7 and 46.8% in 100% FYM condition during first and second season, respectively. Model results showed that, days to 50% silking simulated well in all conditions. However, days to 50% physiological maturity was slightly overestimated. Grain yield was simulated reasonably well under all condition except 100% FYM where it was highly over estimated. Overall the InfoCrop maize model worked satisfactorily and calibrated well for most of conditions and it could be used for simulation of grain yield under alternate nitrogen fertilization situations.
