Abstract

The availability of ultisol soil, in the form of red-yellow podzolic soil, is essential in increasing cocoa production, especially in crop cultivation to meet national cocoa needs. This study aims to assess the effect of rice husk biochar and mycorrhiza, and the interaction of the two treatments on the growth of cocoa seedlings on red-yellow podzolic (ultisol) soil. This study used a quantitative method using Factorial Randomized Block Design (RBD), with 3 blocks as replicates. The first factor is the dose of rice husk biochar consisting of four levels, namely 0 t ha-1 (B0), 10 t ha-1 (B1), 20 t ha-1 (B2), and 30 t ha-1 (B3). The second factor was the dose of mycorrhiza with 4 levels, namely 0 g polybag-1 (M0), 12.5 g polybag-1 (M1), 25 g polybag-1 (M2), and 37.5 g polybag-1 (M3). The data were analyzed using Analysis of Variance and followed by the Post Hoc Tukey’s HSD at α= 5%. The results showed that the application of rice husk biochar at a dose of 30 t ha-1 gave the best results and significantly affected the plant height and crown wet weight of cocoa seedlings compared to the control. In addition, the application of mycorrhiza at a dose of 37.5 g polybag-1 also gave the best results and significantly affected plant height, stem diameter, crown wet weight, and crown dry weight of cocoa plant seedlings compared to the control. However, the interaction between the two treatments did not significantly affect each variable observed.

Abstract

Scallions are high-value economic crop that contains essential nutrients and minerals that support health. This study aimed to determine the effect of various concentrations of liquid organic fertilizer derived from goat urine on the growth and yield of scallions. The research was conducted in Tongko Village, Baroko Subdistrict, Enrekang Regency, from April to July 2025. The Complete Randomized Block Design (CRBD) Single-Factor method was applied in this study, using five different treatments and six replicates. The concentrations of liquid organic fertilizer tested include 0% (0 ml.l-1), 2.5% (25 ml.l-1), 5% (50 ml.l-1), 7.5% (75 ml.l-1), and 10% (100 ml.l-1). The data obtained were analyzed using analysis of variance, followed by the Least Significant Difference test at α 5% significance level. The results showed that applying liquid organic fertilizer derived from goat urine did not affect scallion plant height and leaf number. However, it substantially impacts the fresh and economic weight of the plants, with a concentration 10% (100 ml.l-1) being the best for enhancing the growth and yield of scallions. Further research is recommended to test higher concentrations to achieve maximum scallion growth and yield under field conditions.Keywords: concentrations, goat urine, liquid organic fertilizer, scallion
