The Effect of Various Nutrient Hydroponic Formulation on Growth and Yield of Three Varieties of Common Bean (Phaseolus vulgaris L.) on Hydroponic Drip Irrigation System

Abstract

Common bean productivity has a reduction due to land limitations that are suitable for the common bean crop environment. One of way to resolve this problem is hydroponic cultivation and choosing the best nutrition formula with the best common bean varieties. The research was conducted in March to May 2020 at the Screen house of Padjadjaran University, Jatinangor subDistrict, Sumedang district, West Java. Using a completely randomized design (CRD) of two factors, the first factor was the variety of hydroponic nutritional formulas (Formula Sutiyoso, Formula Aroca, Formula Chaoui, Formula Hoagland) and the second factor was the variety of common beans (Balitsa-1, Balitsa-2, Balitsa-3) thus there were 12 combinations were repeated three times with two plants in each experimental unit. The results showed the interaction between nutritional formulas and common bean varieties on the growth of common bean plants on plant height parameters (14 DAP) and independent tendencies on plant height parameters (7, 21, 28, 35 DAP), leaf area, flowering appear, number of flowers, ratio root loss, dry weight per plant, fresh weight of pods per plant, and grading. The use of Sutiyoso’s formula and Balitsa-1 variety could increase the productivity of common bean plants.
