Abstract

Alang-alang (Imperata cylindrica) and Saliara (Lantana camara) are dominant weeds in several crop cultivation areas, so that when control is carried out, waste from both weeds will be produced in large quantities. Management of waste from both weeds can be done by utilizing it as a more environmentally friendly bioherbicide. Bioherbicide application is carried out pre-growth so that control is carried out faster and attacks newly germinated weed seeds, so that weeds do not appear on the surface and weed control activities will be more efficient. Alang-alang is the most dangerous weed and is highly avoided because it contains allelochemical compounds that can inhibit the growth of the main plant, this compound is found in all parts of the weed but is found most in the roots. Saliara also has a high content of allelochemical compounds which causes a distinctive aroma from its leaves. The allelochemical content of both weeds can be used as active ingredients in bioherbicides and is effective in controlling other weed species. Several studies have reported that bioherbicide extracts from both weeds are effective in inhibiting weed growth so that they can be used as an alternative to herbicides. However, bioherbicide application must be carried out with the right technique and concentration so as not to interfere with and inhibit the growth of the main plant.

Abstract

Abstract. Long beans are one of the horticultural crops that have high economic value and play an important role in meeting the food and nutritional needs of the community. One of the efforts developed to increase the growth and production of long beans is the administration of chicken manure doses combined with eco-enzyme concentrations. This study aims to determine the dose of chicken manure and eco-enzyme concentration in increasing the growth and production of long beans (Vigna sinensis L.). The study was conducted in March 2024 at the Experimental Garden of the Faculty of Agriculture, Indonesian Community Development University (UPMI) Medan using a factorial Randomized Block Design (RAK) with two factors, namely the dose of chicken manure (0, 20, 40, and 80 tons/ha) and the concentration of eco-enzyme (0, 10, 20, and 30 ml/L of water) with three replications. The parameters observed included plant height at 14-35 days after planting (DAP) and pod weight per sample at the end of the observation. The results of the analysis of variance showed that neither the chicken manure dosage nor the eco-enzyme concentration significantly affected plant height and pod weight per long bean sample. Furthermore, there was no significant interaction between the two treatments for any of the observed parameters. This study indicates that under the research conditions, neither the chicken manure dosage nor the eco-enzyme concentration used at the doses used were able to significantly increase long bean growth and production. Therefore, further studies regarding dosage, application time, and soil conditions are needed to obtain a more optimal plant response. Keywords: eco-enzyme, long bean, chicken manure fertilizer, growth, production
