Growth and yield of three bean plant cultivars (Phaseolus vulgaris L) on various planting media hydroponically

Abstract

In the hydroponic irrigation system, the concentration of nutrients given continuously will have an impact on the accumulation of salt compounds in the growing media. Accumulation of salt coumpound in the plant will be inhibit plant growth and decrease plant yield. The research was conducted from March-May 2021 at Jatinagor village. The response of upright bean varieties to the characteristics of the growing medium was different because each varieties need nutrient concentration and water requirement at different level. This study aims to measure the growth and yield of three varieties of beans on different growing media. The research method used was factorial completely randomized design. The first factor is variety (Balitsa 1, Balitsa 2, Balitsa 3) and the second factor is planting media (Husk Charcoal, Cocopeat, Peatmoss). Each experimental unit was repeated three times. The observed growth and yield parameters were plant height 21 days after planting, leaf area, number of pods and pod fresh weight per plant. The observed data were then analyzed using analysis of variance at the 5% level and Duncan's distance difference test at the 5% level. The analysis showed that there was no interaction between varieties and growing media. The independent effect of varieties and planting media occurred on leaf area and number of pods, while plant height and pod fresh weight per plant were influenced by the type of variety. The Balitsa 3 variety increase 122% of yield and the husk charcoal growing media showed the best growth and yields.
