SISTEM POLA TANAM DI WILAYAH PRIANGAN BERDASAKAN KLASIFIKASI IKLIM OLDEMAN

Abstract

Priangan region is the largest food distributor in Indonesia. It has fertile land because there are mountain ranges and river flows. Research on climate conditions of Priangan should be done to determine cropping system in the region. Rainfall is climate element which analyzed in this research because it influences on plant growth directly. It is clear especially in farming areas which required a systematic and simple method to understand the behavior of climate. Oldeman classification system is useful in the classification of agricultural crops in Indonesia by using rainfall element. The criteria are based on the calculation of wet months and the dry season. By using climate classification, Oldeman cropping system can be determined in the region. Based on Oldeman climate classification, most of Priangan region can be classified in climate type B1, B2, C1, C2 and C3. The wettest climate type in the region is B1, it is suitable to be planted rice short lifespan of 3 (three) times the rice harvest or short life of 2 (two) times the harvest and crops 1 (once) harvests. The driest type is C3 which fits the short lifespan of cultivated rice 1 (once) and harvest crops 2 (two) times which the second harvest in the dry season.
