 Abstract: The aim of this research was to determine heat unit (degree days) of tomato that growing in greenhouse. Heat unit was used to determine growing and development stage of tomato. Tomato was plannted in greenhouse during August until December 2010 at Balitklimat, Cimanggu, Bogor. The weather data consist of air temperature, minimum and maximum temperature, relative humidity, and solar radiation intensity collected by using authomatical weather station (aws). The result of the research showed that heat unit of tomato was 1,734oC days. Average of air temperature in greenhouse was 27.0oC and average of relative humidity was 74.2%.
Keywords: Heat unit, growing, development, tomato
