Abstract

One of the obstacles in providing irrigation water is the difficulty in determining the right parameters to be used in the controlling of timing and amount of irrigation water according to crop needs. One of the alternative parameters that could be considered in order to meet the water needs of plants is the irrigation control based on evaporation. This study aims to produce an evaporative irrigation system design and determine the crop coefficients of pepper. The drip irrigation network consists of a supply tank and distribution pipes that provide water to the plant pots. The network valve opening and closing arrangements are made based on the evaporation in the supply tank. This research was conducted in a plant house for 5 months by observing the observations made on the water balance components, including the rate of evaporation which is measured based on changes in the water level in the water supply tank. The results showed that the evapotranspiration outside the houseplant was greater than that in the plant house. At the beginning of planting pepper, the evapotranspiration was 5.2 mm/day in the plant house and 4.9 mm/day outside. The average evapotranspiration during observation inside the plant house was 4.1 mm/day and 3.8 mm/day outside. Meanwhile, evaporation outside the plant house is smaller than that inside the plant house which ranges from 2-5 mm/day. Provision of water with this evaporative irrigation system of 5.2 mm/day has been able to meet the needs of 4.1 mm/day of evapotranspiration water for pepper plants. The provision of water has been able to encourage the growth of primary branches and flowering. Normal pepper plant growth during this study with calculated crop coefficients ranging from 0.1–0.7.

Abstract

Organic vegetables grown special in planthouses require  special irrigation practice to maintain  the optimum range of soil water content throughout the cultivation season. The problem of irrigation is the absence of parameter that used to determine schedule and water irrigation. This research was to figure out whether the sprinkle irrigation used for Kailan vegetable in a planthouse could fulfil the water demand and the total water consumption based on change of water content. Herewith, the daily soil moisture was observed and analyzed the water flow in the soil based on the soil physical and hydraulic properties. The result showed that the soil water content  was always within field capacity and permanent wilting point but 87% of cultivation period was lower than readily avaiable water (RAW). This condition indicated that the water irrigation is not optimal. Based on change of soil water content analysis, water consumption for kailan was 55  mm during cultivation with  the consumption rate was 1.1 mm/day. The water requirement to attain RAW condition was 130 mm.
