Amount of applications biofertilizer and biological control agents (Beauveria bassiana Vuill) on growth and yield of red chili (Capsicum annuum L.)

Abstract

High chili production is inseparable from proper fertilization and control of pests and plant diseases. This is done because red chili is a plant that is quite susceptible to attack by pests and diseases, resulting in disruption of growth and decreased production of red chili. Efforts that can be made to overcome this problem are by applying biofertilizer and entomopathogenic fungi (Beauveria bassiana) as biological control agents. The application is expected to increase the production of red chili plants and reduce the use of inorganic fertilizers and chemical pesticides. The research objective was to determine the effect of amount of applications biofertilizer and biological control agents on red chili production. This study used a factorial completely randomized design consisting of two factors where the first factor was amount of applications biofertilizer and the second was amount applications of biological control agents. Each factor consists of four levels, namely zero time, one time, twice, and three times applications. The results showed that amount of applications three times of biofertilizer and biological control agents tended to give the best response to the yield of red chili.
