Abstract

The problem faced by hydroponic farmers in cultivating chili peppers is the lack of an optimal AB Mix nutrient formula that can be synthesized independently using chemical fertilizers readily available in agricultural supply store. This study aims to evaluate the effects of AB Mix nutrient formulation and variety on yield of curly chili peppers (Capsicum annuum L.) in hydroponic system. The experimental design was a Randomized Block Design (RBD) in 2-factor split-plot arrangement with three replications. The main plots consisted of four nutrient formulations. The subplots consisted of plant varieties, which included the Lado Juara F1 variety, the Joker genotype, and Lolay genotype. The result of the study showed that increasin of the concentration of the AB Mix nutrient formulation from N1 to N2 enhanced the number of fruits and the fruit weight per plant, both in the Lado Juara, Joker, and Lolay varieties. However, further increases the concentration of the AB Mix nutrienr formulation from N2 to N3 and N4 decreased the number of fruits and the fruit weight per plant in any of varieties. The use of the Lado Juara variety resulted in higher numbers of fruits and fruit weight per plant compared to the Joker and Lolay genotypes across all AB Mix nutrient formulations with a drip irrigation hydroponic system. Key words: Chili, formulation, hydroponic, nutrition, variety

Abstract

Plant growth promoting rhizobacter (PGPR) contains Rhizobacter which can fix free nitrogen found in nature, the nitrogen is converted into ammonia which is then distributed to plants. The aim of this research was to determine the effect of administering pgpr from two different bioactivator sources on the intensity of aphid attacks on chili plants. The experimental design used was a Completely Randomized Design (CRD) which consisted of two factors, namely the PGPR concentration of bamboo roots and mimosa roots, namely 0%, 25%, 50%, 75% and 100%. Each treatment was repeated 3 times with each experimental unit consisting of 4 curly chili plants of the Thunder 99 variety. Applications were carried out once a week during the vegetative period. Observations began at 1 WAP and once a week with the observation variables being the type of aphids and the intensity of aphid attacks on each plant during the vegetative period. The results obtained by administering PGPR bamboo roots and putrimalu roots were less effective because they were unable to suppress the intensity of aphid attacks on chili plants. Intensity of aphid attacks not different than control. The level of intensity of aphid attacks is directly proportional to the aphid population. PGPR that can relatively reduce the intensity of aphid attacks is bamboo root treatment with a concentration of 75%. A better PGPR bioactivator comes from bamboo roots rather than mimosa roots.
