Two varieties of sweet corn were compared; Gold Rush and Chocolate in this study. Three fertilization regimes were used: 1. Organic (1200 kg/ha); 2. Organic (600 kg/ha) and half urea (86.5 kg/ha); 3. Di amino phosphate (DAP) (50 kg/ha) and urea (173 kg/ha). Same irrigation amount was applied for all plots by using furrow irrigation method. NDVI was estimated by using RS technique to determine vegetation index. By using same technique canopy temperatures were estimated. Chocolate variety was highest in NDVI value (0.58) when Organic+Half Urea was applied. Plant height and leaf area were measured from each plot. Gold Rush variety produced the tallest plant with 119.4 cm at the Organic+Half Urea fertilizer application. The biggest leaf area (46.08 cm2) was measured from Gold Rush variety with DAP+Urea fertilizer application. Sugar content also determined by using Rea fracto meter. The highest sugar content was 14% for the Gold Rush variety by applying Organic+Half Urea and DAP+Urea. When all findings were evaluated, Organic+Half Urea fertilizer application was found to give better results.
