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).
This research was conducted to examine the effect of compost and biochar on the growth and yield of red chili plants. This research is a factorial experiment using Randomized Block Design (RBD), which consists of two factors: compost (0, 10, 20, and 30 tons ha−1) and the type of biochar (bamboo and coconut shell). The interaction between compost and biochar did not have a significant effect on all variables observed in this study. The dosage of compost has a significant effect on fruit length, fresh fruit weight, and fresh weight of roots. The biochar treatment does not have a significant effect on the observed variables except for the number of fruits that have a significant effect. The treatment of various dosage levels did not show any significant difference, but the application of 30 tons ha−1 compost produced the highest fresh fruit weight of 185.35 g or increased by 20.94% when compared to the treatment without compost of 153.26 g. The treatment of this type of biochar only had a significant effect on the number of chili fruit, namely coconut shell biochar which gave the highest value of 17.17 chilies and was significantly different from bamboo-based biochar which produced 15.00 chilies.
This study aims to determine the effect of biochar dosage and compost fertilizer and its interaction on the growth and yield of corn crops. This experiment used a randomized block design (RBD) with a factorial pattern consisting of 2 factors. The first factor was the dose of biochar (B) consisting of 4 levels, namely: 0 ton ha-1 (B0), 5 ton ha-1 (B1), 10 ton ha-1 (B2), 15 ton ha-1 (B3). The second factor is the dosage of compost fertilizer (K) consisting of 2 levels: 0 ton ha-1 (K0), and 20 ton ha-1 (K1). The results showed that the interaction between the treatment of biochar dose and compost fertilizer had no significant effect on all observed variables. Biochar and compost treatment have significant effect to most observed variables, except on leaf area and harvest index have no significant effect. Treatment of biochar with a dose of 10 ton ha-1 gave the highest dry kiln seedlings weight of 7.83 tons increased by 35.60% compared to the lowest dose without biochar of 5.77 tons. Treatment of compost doses of 20 ton ha-1 gave the highest dry seed oven per hectare weight of 7.42 tons increased by 16.60% when compared with the lowest yield on treatment without compost dose as much as 6.37 tons.
Abstract This study aims to determine the effect of compost and biochar fertilizer at a dose of 15 tons ha-1 made from livestock manure and its interaction on the growth and yield of red chili plants. This research was conducted in Blahkiuh Village, Abiansemal District, Badung Regency, Bali with an altitude of 400-500 m above sea level. This research was started from February 2020 to July 2020. The design used in this study was a factorial randomized block design (RBD) consisting of 2 factors, namely: chicken compost with 4 levels and biochar 2 levels by testing the types of compost and biochar. The interaction between the treatment effect with the type of compost and the type of chicken biochar had no significant effect on all observed variables. The treatment of compost application had a significant to very significant effect on most of the observed variables, except for the number of leaves, which had no significant effect. The treatment of chicken biochar dosing had a significant to very significant effect on most variables except for the maximum number of leaves and fresh weight per fruit, which had no significant effect. The results showed that the highest fresh fruit weight was obtained in the type of compost given by chicken livestock, namely 1499.56 g or an increase of 46.46% compared to the lowest treatment obtained without compost, namely 1023.85 g. To increase the growth and yield of red chili plants, it is recommended to use compost types of chicken livestock and chicken biochar at a dose of 15 tonnes ha-1 and further research is needed on the provision of biochar and compost types at different locations and types of plants. Keywords: compost, biochar, and chili plants.
