THE DROUGHT VARIABILITY ANALYSIS FOR RICE PRODUCTION USING STANDARDIZED PRECIPITATION INDEX (SPI)

Indramayu regency is the second largest producer of rice in West Java that is susceptible to drought events. The influence of ENSO give a bad impact on rice production which causes tens of thousands hectares of rice crops suffer parched during drought. The drought variability contributes in the prod...
