The effect of the type of planting medium and the dosage of vermicompost fertilizer on the growth and yield of bean (Phaseolus vulgaris L.) Kenya varieties

Abstract

The superiority of the Kenya variety of beans has the opportunity to increase export value; with good market prospects, it is necessary to increase the production of Kenyan varieties of beans. This study aims to determine the effect of the type of planting medium and the dosage of vermicompost fertilizer on the growth and yield of green beans. This research was conducted from February until April 2020 in Ngamprah, Kab. West Bandung, West Java. This research was conducted using an experimental design in the form of a factorial randomized block design (RBD) with three replications consisting of two factors. The first factor is the type of planting media which consists of 3 levels (m0 = soil, ml = soil + rice husk charcoal (1 : 1), m2 = soil + cocopeat (1:1)). The second factor was vermicompost consisting of 4 levels (k0 = 0 t ha-1, k1 = 7.5 t ha-1, k2 = 15 t ha-1, and k3 = 22.5 t ha-1). Based on the study results, there was an interaction between the soil planting media with a dosage of 15 t ha-1 of vermicompost on the growth and yield of upright beans. Soils with a silty loam texture and high P nutrient content in vermicompost can support growing places and sufficient nutrient availability for the growth and yield of upright beans.
