Abstract

Aria Lafansa (164110240) research with the title "The Effect of Residues of Biochar and Nasa POC on the Growth and Production of Peanut (Arachis Hypogaea L.)". The purpose of this study was to determine the interaction effect and the main effect of Nasa biochar and POC residues on the growth and production of peanut plants. The design used in this study was a factorial completely randomized design consisting of 2 factors. The first factor is biochar residue which consists of 4 levels of treatment, namely biochar dose 0; 0.7; 1.4 and 2.1 kg per plot. The second factor was POC Nasa which consisted of 4 treatment levels, namely concentrations of POC Nasa 0, 3, 6 and 9 ml/L water. Each treatment combination was repeated three times, each experimental unit consisted of 12 plants. The results showed that the interaction of biochar residue and Nasa POC had a significant effect on flowering age, relative growth rate, harvest age, number of pods per plant, wet pod weight per plant, wet pod weight per plot, dry pod weight per plant, and dry seed weight. per plant. The best treatment was a combination of biochar treatment, a dose of 2.7 kg/plot and POC Nasa, a concentration of 9 ml/liter of water (B3P3). The main effect of biochar residue was on flowering age, relative growth rate, harvest age, number of pods, weight of wet pods per plant, weight of wet pods per plot, weight of dry pods per plant, weight of dry seeds per plant, and harvest index. The best treatment was biochar treatment, a dose of 2.1 kg/plot (B3). The main effect of POC Nasa was significant on flowering age, relative growth rate, harvest age, number of pods, weight of wet pods per plant, weight of wet pods per plot, weight of dry pods per plant, weight of dry seeds per plant, and harvest index. The best treatment was found in the POC Nasa treatment, a concentration of 9 ml/liter of water (P3).
