UJI APLIKASI BIOCHAR SEKAM PADI DAN POC TITHONIA UNTUK PENINGKATAN PERTUMBUHAN DAN PRODUKSI TANAMAN KACANG TANAH (Arachis hypogaea L.)

Abstract

Research titled application test of rice husk biochar and tithonia for the improvement of growth and production of peanut plants (Arachis hypogaea L.) was conducted at the Experimental Farm of the Faculty of Agriculture, Islamic University of Riau. The research aimed to determine the effect of rice husk biochar and tithonia liquid organik fertilizer on the growth and production of peanut plants. The study used a factorial completely randomized design. The first factor was the dose of rice husk biochar consisting of 4 levels 0 kg/plot; 0,6 kg/plot, 1,2 kg/plot, dan 1,8 kg/plot. The second factor was the concentration of tithonia liquid organik fertilizer consisting of 4 levels 0 ml/l, 200 ml/l, 400 ml/l, dan 600 ml/l. There were 16 treatment combinations with 3 replications, resulting in 48 experimental plots. The observational data was analyzed using analysis of variance and further tested with the Honest Significant Difference (HSD) test at a 5% significance level. The parameters observed included plant height, relative growth rate, flowering time, harvest time, number of pods per plant, percentage of filled pods, dry pod weight per plant, dry seed weight per plant, and weight of 100 seeds. The results showed that the interaction and main effects of rice husk biochar and tithonia LOF had significant effects on all observed parameters. The best treatment was found in rice husk biochar at 1.8 kg/plot and tithonia LOF at 600 ml/l. The main effect of rice husk biochar significantly affected all observed parameters, with the best treatment found in rice husk biochar at 1.8 kg/plot. The main effect of tithonia LOF significantly affected all observed parameters, with the best treatment found in tithonia LOF at 600 ml/l.
