Abstract

Climate is one of the essential factors effecting agricultural production. Better understanding it potential and characteristic would pave the way to gain the optimal agricultural production. The variation of elevation effected rainfall that furthermore determined the dynamic of soil water availability and planting calendar. In dry land farming, the ultimate source of agriculture water is from the rainfall. It is understandable that to secure the farming process and/or to boost the production, the optimal use of climate resources is essential. The research with the aims to determine a planting calendar using Agricultural Rainfall Index (ARI) method and to determine the effect of elevation on planting calendar in West Timor has been conducted. The backbone of the study is by the analysis of climatology data that consists of rainfall, temperature and evapotranspiration data. The data based on the ten days series data of 20 consecutive years. The data was covered 16 climatology local stations that disperse in four districts namely Kupang, Timor Tengah Selatan (TTS), Timor Tengah Utara (TTU) and Belu. Total coverage rain fed areas is 14,635 Ha from total potential agricultural areas of 48,509 Ha. The planting calendar was determined using ARI Method while the identification of the relation regarding elevation and planting calendar was using statistical approached of regression and correlation. The results show that planting calendar has a variation from 130.25 – 190.25 days; furthermore there is a strong correlation between elevation and planting calendar that indicated in correlation coefficient of 0.81. Moreover, the research shows that with the increase of elevation there is an increase of planting calendar. The strong relation meet the polynomial function of Y = 13.54 – 0.04X + 9x10-6 X2 with the determination coefficient (R2) of 0.820.
