Effect of Concentration and Time of Chitosan Application on Pachira Breeding (Pachira Aquatica)

Abstract

Abstract Pachira is an ornamental plant that can be used as biodiesel, because of the high fat content in the seeds. Biodiesel is an alternative fuel that can be used to replace fossil fuels. By using biodiesel as a fuel, it will support a sustainable agricultural system that can produce energy for other sectors outside of agriculture. Pachira plant breeding has not been widely carried out in Indonesia, so the potential use of pachira seeds as biodiesel has not been highlighted. The aims of the study is to determine the concentration and timing of chitosan application for pachira breeding. This study was conducted in Blora Regency using a completely Randomized Block Experimental Design (RCBD) with two treatment factors, namely concentration and time of application. The concentration was divided into three levels, namely 1%, 2% and 4% concentration, the time of application was divided into three levels, namely in the morning, afternoon, morning and afternoon. The application of chitosan was carried out every week as much as 20 ml according to the treatment. Maintenance carried out is to pour 50 ml of water every day on all research samples. The results showed that treatment with a concentration of 4% and watering in the afternoon could stimulate plant height growth at the beginning of the seedling phase, having the most leaves, producing greener leaf colors and having wider roots.
