Abstract :
Combined organic and inorganic fertilizers is an effort to improve soil quality and good production results. This research aims to determine combination of banana peel poc and inorganic fertilizers combination on increasing productivity of corn. This study was conducted in May-August 2021 with a randomized block design (RAK) single factor that is without banana peel poc + P1:(urea 350 kg/Ha, SP-36 200 kg/Ha, KCl 100 kg/Ha), A1: banana peel poc 20 ml/L + 7 times watering + P2:(urea 150 kg/Ha, SP-36 100 kg/Ha, KCl 50 kg/Ha), A2: banana peel poc 20 ml/L + 3 times watering + P2:(urea 150 kg/Ha, SP-36 100 kg/Ha, KCl 50 kg/Ha), A3: banana peel poc 20 ml/L + 2 times watering + P2:(urea 150 kg/Ha, SP-36 100 kg/Ha, KCl 50 kg/Ha), A4: banana peel poc 30 ml/L + 7 times watering + P2:(urea 150 kg/Ha, SP-36 100 kg/Ha, KCl 50 kg/Ha), A5: banana peel poc 30 ml/L + 3 times watering + P2:(urea 150 kg/Ha, SP-36 100 kg/Ha, KCl 50 kg/Ha), A6: banana peel poc 30 ml/L + 2 watering times + P2:(urea 150 kg/Ha, SP-36 100 kg/Ha, KCl 50 kg/Ha), A7: banana peel poc 40 ml/L + 7 times watering + P2:(urea 150 kg/Ha, SP-36 100 kg/Ha, KCl 50 kg/Ha), A8: banana peel poc 40 ml/L + 3 times watering + P2:(urea 150 kg/Ha, SP-36 100 kg/Ha, KCl 50 kg/Ha), A9: banana peel poc 40 ml/L + 2 times watering + P2:(urea 150 kg/Ha, SP-36 100 kg/Ha, KCl 50 kg/Ha). The results showed that the banana peel poc treatment concentration of 40 ml/l and 2 waterings, 30 ml/l and 3 waterings, 30 ml/l and 2 waterings with a combination of half dose of inorganic fertilizer:(urea 150 kg/Ha, SP-36 100 kg/Ha, KCl 50 kg/Ha) could give results that were not significantly different.
