Manure Utilization from Cows, Goats, and Chickens as Compost, Biochar, and Poschar in Increasing the Red Chili Yield

This study aimed to determine the characteristics of biochar, compost, and poschar from livestock manure waste and its effect on the yield of red chili plants. Randomized Block Design (RBD) with nested patterns was used in this study. The treatment composition consisted of 9 types of fertilizer (cow compost, goat compost, chicken compost, beef biochar, goat biochar, chicken biochar, beef poschar, goat poschar, and chicken poschar), and 3 levels of fertilizer doses (5, 10, and 15-ton ha -1 ) and one control treatment. The results showed that the type of fertilizer treatment did not significantly influence all observed variables, except the maximum plant height and fresh weight of shoot had a very significant effect. While the dose of fertilizer did not have a significant effect on most of the variables observed except for the height of the chili plant, the weight of the fresh stem and leaves, and the weight of the fresh chili harvested. In various types of fertilizer treatments, the maximum plant height obtained in chicken biochar (111.53 cm), which shows a slight difference when it was compared with the lowest plant height of 99.58 cm in biochar goat. The treatment of compost, biochar, and poschar sourced from 15 tons ha -1 chicken manure achieved the highest yields of fresh weight of chili harvested respectively 266.06 g, 270.95 g, and 280.05 g which were significantly increased 39.16%, 41.72%, and 46.48% compared with control (without treatments).
