Increased yield and quality of corn by inorganic fertilizers and utilization of corn as food to support food security

Abstract

This research was carried out in two stages, three replications. The first stage was to determine the effectiveness of NPK 26-12-12 fertilizer on the yields and quality of corn. Corn with the best quality obtained from the best treatment of fertilization results at the first stage, was used as raw material in the second stage; namely noodles production. The second stage was to determine the quality of corn noodles. The factors that were used in the first stage were the combination dose of NPK 26-12-12 + urea + KCl which was compared to NPK 15-15-15 + urea + KCl (there are nine treatments). The factors that were used in the second stage was the percentage of corn flour (0; 10; 20; 30; 40; 50; 60%). The results of the first research found that the application of NPK fertilizer can increase the vegetative growth of corn plants, the highest yield was in the G treatment which produced a harvest of 6.94 t / ha; R/C ratio 1.56 and RAE 181. The results of the second research found that the addition of corn flour affected the quality of corn noodles. Panelists like noodles with the addition of 30% corn flour.
