Water Harvesting System as an Alternative Appropriate Technology to Supply Irrigation on Red Oval Cherry Tomato Production

Abstract

Water harvesting is a system which starts from harvesting rainfall in the wet season and collecting it in the big torrents, as irrigation resources and applied to the crops in the dry season for increased crop production. Horticulture crops such as red oval cherry tomato is predominantly an Indonesian crops for domestic and to support agro-industry sectors, which requires effective and efficient water management practice during the growth periods. Modification of irrigation system needs to optimize water and improve the red oval cherry tomato production. The study aims to find out water used by red oval cherry tomato with related irrigation resources from a supply of water harvesting as an appropriate technology in the dry season. The research was carried out at the greenhouse located in Universitas Padjadjaran; West Java, Indonesia from January to Mei 2017. The research method is descriptive analysis with cultivated of red oval cherry tomato and planted it on the autopot with growth media uses mixed of husk charcoal and zeolite with ratio 9:1 with 15 cm height. This study discovers that the rainwater harvesting as a source of irrigation on self-watering fertigation system using autopot can be beneficial for red oval cherry tomato yield.
