Abstract : The production of agricultural crops depends on the optimization rate of plant genetic factors, climatic and soil factors and the level of agrochemicals. This factors are in constant dynamism and also is the production of agricultural plants. Changing in climatic conditions of the area will necessitate bring changes in the genetic resources of the plants that will be cultivated as well as in the technology of cultivation. Climate data of recent decades have shown steady rise in temperatures and significant changes in the amount of precipitation and its distribution. Experimenting in relation with the optimal timing of planting of different sugar beet cultivars, constitutes a necessity to adapt to climate change. The study was based on a multi-year analysis of climate indicators in the Korça region, analyzing the performance of morphological, physiological and productive indicators of sugar beet cultivars planted at different time periods. Experimental conclusions are based on the statistical analysis of factors variance two (sugar beet genotype x different planting time. The planting time, which is essentially determined by the optimum agronomic temperature, determines the entire biological cycle of the plant by directly influencing the morphologic and plant yield. Sustainable agricultural development determined by long-term climate change requires adaptation to these changes
