Abstract
Green bean productivity is closely related to the accumulation of photosynthesis translocation. Organic base matter for fertilizer and mulch provide eco-friendly system to support plant productivity. Liquid organic fertilizer and types of organic mulch serve the optimum condition for growing environment of green beans. This study aimed to determine the concentrations of liquid organic fertilizer and types of organic mulch toward biomass addition in green beans. The experiment was conducted on Andisol soil in Cisalak, Subang West Java from January to March 2018. A factorial randomized block design was used to arrange the first factors i.e. 0 ml l-1, 1 ml l-1, 2 ml l-1, and 3 ml l-1 liquid organic fertilizer and the second factors i.e. without mulch, paddy straw mulch, and reeds mulch. The results obtain no interaction between liquid organic fertilizer and types of organic mulch for numbers of pod per plant, pods weight per plant, dry stover weight, shoot root ratio and harvest index. Liquid organic fertilization in 2 ml and paddy straw mulch, independently, gave the best recommendation to increase green bean productivity.
