ABSTRACT: The analysis of agro-climatic data of Côte d’Ivoire ranging from 1951 to 2000 have permitted to highlight normal, early and delayed dates of onset and retreat of rainfall for the beginning and end of growing season. The analysis is based on SIVAKUMAR method and was performed with the INSTAT software. It takes into account several land and agricultural parameters. The specific parameters of Côte d’Ivoire were calibrated for a suitable running of the model over the country. The results were then integrated to a mapping process based on ordinary kriging to get a geographical coverage. A comparative study of growing season of the average 1971-2000 (Dry period) with the average 1951-1980 (Humid period) show a shortening of the growing season mainly in the Center-Western region were we record a shortening of 30 days.
