Peanut is one of the plants, especially food sources of protein, carbohydrates and vitamins.
Objective to determine planting peanuts (Arachis hypogaea L.) based on water balance in the
District of West Kakas. Materials and equipment used are secondary data of rainfall and
evapotranspiration taken in Tondano Geophysics station, as well as physical data of land and
uses a computer. The method used in this research is secondary data in the form of a survey
method that includes climate data of rainfall and evapotranspiration observations
Geophysics Station Tondano Winangun obtained from BMKG station. Soil physical data
retrieval in Minahasa District Land Board. Early planting peanuts based on the criteria of
