Abstract
One of the efforts to increase edamame’s productivity is to increase soil productivity by using organic fertilizers. This study aimed to determine the effectiveness of compost application with the reduction of inorganic fertilizers on the growth and production of edamame soybeans. The study was conducted at the Experimental Garden of the Faculty of Agriculture, University of Muhammadiyah Jakarta, from November 2020 to March 2021. The study used a randomized complete block design (RCBD), with five treatments, namely control (100% Recommendation Dose (RD) of inorganic fertilizer), 50% RD of inorganic fertilizer + compost 25 g plant-1, 50% RD of inorganic fertilizer + compost 37.5 g plant-1, 50% RD of inorganic fertilizer + compost 50 g plant-1, and 50 % RD of inorganic fertilizer + compost 62.5 g plant-1. The results showed that compost reduced the use of inorganic fertilizers by 50% with the recommended amount of compost being 25 g plant-1.
