Abstract

This study presents an investigation into the optimal concentration of binahong (Anredera cordifolia) extract for enhancing the growth, yield, and mitigating leaf blight in shallots. Conducted within a controlled environment at a well-established laboratory, the experiment employed a completely randomized design (CRD) to evaluate the effects of five different concentrations of binahong leaf extract. Data analysis included variance tests, and when significant effects were identified, Duncan's multiple range test (DMRT) was employed to further examine the results. The findings demonstrate that a 30% concentration of binahong (Anredera cordifolia) extract significantly improves growth, yield, and effectively suppresses the development of Red onion(Allium ascalonicum L.)  leaf blight. Moreover, this concentration resulted in a wet tuber weight per hill of 76.30 g. These insights contribute to the development of sustainable agricultural practices and offer a promising alternative to chemical-based treatments for managing crop diseases, thereby advancing our understanding of the potential applications of binahong (Anredera cordifolia) extract in agricultural settings.

Abstract

The objective of this experiment was to investigate the interaction between the application of banana stem compost and tofu industry liquid waste on the growth and yield of Bird's Eye Chili (Capsicum frutescens L.). The experiment followed a factorial completely randomized design (CRD) with two factors: the first factor being the application of banana stem compost with four levels: 0 g/polybag, 100 g/polybag, 200 g/polybag, and 300 g/polybag; the second factor being the dosage of tofu industry liquid waste with three levels: 0 ml/L water, 50 ml/L water, and 100 ml/L water. Based on the research findings, it can be concluded that the application of 300 g/polybag of banana stem compost and 100 ml/L of tofu industry liquid waste resulted in increased fruit weight in Bird's Eye Chili, with a yield of 107.87 g.

Abstract

This study aims to investigate the combined impact of Chitosan and Tithonia (Tithonia diversifolia) Compost on the Growth and Yield of Peanut Plants (Arachis hypogaea L.). A factorial randomized block design (RBD) was utilized for the experiment. The first factor was Tithonia compost in quantities of 0 tons/ha-1, 5 tons/ha-1, and 10 tons/ha-1. The second factor was Chitosan, applied at three dosage levels: 0 ml/l water, 3 ml/l water, and 6 ml/l water. The results suggest that the use of Tithonia compost effectively enhances plant height, flowering age, harvest age, 100-seed weight, and dry pod weight per hill when applied at a dose of 10 tons/ha. Furthermore, Chitosan administration was found to increase the number of effective root nodules when used at a concentration of 6 ml/l water. The interaction between Tithonia compost and Chitosan also resulted in an extended flowering life and an increase in dry pod weight per hill of peanut plant. Based on these findings, we recommend using 10 tons/ha of Tithonia compost and 3 ml/l water of Chitosan in peanut cultivation for optimal results.
