An experiment was conducted at Crop Research Farm, Department of Agronomy, SHUATS, Allahabad, (U.P) during kharif season of 2016. The study was conducted to find out the effect levels of nitrogen and sulphur on growth and yield of hybrid maize (Zea mays L.). The experiment was laid out in RBD having 12 treatments replicated thrice and it consisted of 3 levels of nitrogen viz. 100kg N, 120kg N and 140kg N and 4 levels of sulphur viz. control, 15kg S ha-1, 30kg S ha-1 and 45kg S ha-1. The experimental findings record that the maximum plant height (198.67cm), maximum plant dry weight (178.09g), LAI (5.16), length of cobs with and without husk (27.67cm and 20.83cm), respectively. Grain rows cob-1 (16.07) and grains row-1 (30.15), 1000- grain weight (238.67g) and grain yield (9717kg ha-1) were recorded in treatment T11(140 kg N ha-1+ 30 kg S ha-1) followed by treatment T7 (120kgNha1+ 30 kg S ha-1) and it was concluded that nitrogen and sulphur significantly influenced the growth parameters and yield of hybrid maize and higher level of sulphur i.e. 45kg/ha increased the cost of cultivation and also had antagonistic effect on yield attributes of maize.
