Abstract

Evalusai nature of rainfall and water balance in this land for planning pertanaman chili as well as demonstrate a period of surpluses and deficits in order to provide optimum results in the production of chili. The purpose of the evaluation research to find out the nature of rainfall and water balance of land on pertanaman cayenne pepper in the Regency of Gorontalo. This research was carried out from April 2017 until August 2017. The tools and materials used in this research is the daily climate data (minimum temperature, maximum temperature, wind speed, solar radiation, humidity and precipitation) from the Gorontalo Airport Djalaludin BMKG Station for 10 years (years 2008-2016). Acreage data, extensive harvesting (production) cayenne pepper plants in the Regency of Gorontalo during the last 10 years of relevant agencies and data of the soil (soil moisture, crop coefficient, and the permanent wilting point). The methods used in this research is a method of prediction methods and arithmetic kuantitaif evapotranspirasi FAO Penman Monteith. Research results show that the nature of the rainfall in Gorontalo walayah generally are normal (N) and the average percentage of 36%, however the properties under normal (BN) has strong influence with the average percentage of 33%. Water balance analysis based on land within the last ten years shows that in 2014 the deficit occurred year round water for 6 months and getting worse by the year 2015 the water deficits occurred during 8 months, known as the El nino very powerful, so this affects crop production of chili.
