| Summary: | Green beans (Phaseolus vulgaris L.) is a legume plant that has high nutritional value and contributes to household welfare improvements. The household is encouraged to be an important actor in fulfilling nutrition and a modeling approach of water needs is required in household-scale cultivation for the implementation of the Hyper Urban Farming system. This study used a Capillary Wick Irrigation system in unshaded and shaded conditions. The plant water needs of actual evapotranspiration were obtained by weighing the water loss every 3 days and compared with the evapotranspiration of the Penman-Monteith method. The results showed that the unshaded treatment was better than the shaded treatment in terms of growth and harvest biomass. The k value (multiplier) between the actual evapotranspiration of the capillary wick irrigation system towards the Penman-Monteith method was 2.61 with R2 of 0.975 for the unshaded condition and 4.91 with R2 of 0.994 for the shaded condition. Actual evapotranspiration showed a correlation with plant growth, and there was a significant difference between plant growth and dry weight planted in both unshaded and shaded conditions.
