Abstract

A two years field trial was carried out at New Developmental Farm (NDF), the University of Agriculture Peshawar to find out the AMELIORATIVE effect of nitrogen (N) and sulfur (S) on quality of different maize hybrids. Inorganic N was applied @ 0, 250, 300 and 350 kg ha-1, whereas S was applied @ 0, 20, 40 and 60 kg ha-1. Both N and S were kept in main plots. Maize hybrids used were R-3305, R-2210 and R-2207 respectively, allotted to sub-plots. S levels had non-significant effect on protein (%), whereas oil (%) was significantly affected and maximum oil (6.22%) was found in plots receiving maximum level of S (60 kg ha-1). N levels had opposite effect on these quality parameters as protein significantly affected, and maximum protein (11.91%) was found in plots with maximum level of N (350 kg ha-1). Among hybrids R-2210 was found with maximum oil (5.64 %) and maximum protein (10.44 %), as compare to other two hybrids i.e. R-3305 and R-2207. Years had significant effect on protein as compare to oil (%). Hence N and S can play a significant role in improving the quality of corn hybrids and can be manipulated according to the needs of the farmer and situation.
