The production of agricultural crops depends on the optimisation rate of plant genetic factors, climatic and soil factors and the level of agrochemicals. These factors are in constant dynamism and also are 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. The study analyses the thermal and pluviometry performance of the Korça field, one of the areas with the best agricultural development and on this basis is experimented with the time of potato planting and the adaption to these changes. The analysis of climate variability and trends of ecological climate factors is determining for the sustainability of agricultural production. Especially the increase in temperature indicators requires adaptation to the changes in the technology of crops cultivation. 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. Climate changes of the last decades make experimentation necessary to determine the optimal planting terms. Sustainable agricultural development determined by long-term climate change requires adaptation to these changes.

The productivity of agricultural crops depends on an optimal degree of genetic factors, climate, soil and level of agrotechnology. Climate changes have a significant negative impact on the productivity of agricultural crops. The study is focused on a multi-year analysis of the main climate indicators, such as temperature and precipitation. The data collected from hydrometeorological stations in the Korça region of Albania were processed and compared with the corresponding data from two previous 30-year periods. The increase in temperature indicated a trend without significant volatility from one year to the next, and the annual amount of precipitation did not fundamentally change; however, a greater concern was the amount of rain that fell over fewer days but in larger amounts. Moreover, the structure of the diagram which integrated temperature and average monthly rainfall showed that there had been an increase in the periods of drought. The changes in agro-climatic indicators present a challenge for producers in the field of agriculture if they are to meaningfully remodel agricultural areas and determine the most appropriate cultivation technologies for agricultural crops.

Agricultural crops productivity depends on the optimum degree of genetic factors, climate, soil and the level of agro-technology. These factors are changing constantly. The study is focused in a multi-year analysis of the climatic indicators in the region of Korça, by analysing the impact of these changes on the performance of morphological, physiological and production indicators of barley cultivars. The experimental part of the study identified the most suitable barley cultivars and planting period in response to climate changes. The observed data for the time period 2018–2021, and their comparison with a 30-year range period 1961–1990, indicated an increase by 1.8°C of the average atmosphere temperature. During the years of the study, the annual average amount of precipitation has shown not significant changes, but is observed less rainy days with high intensity. The application of the integrated Bagnoulus & Gaussen method indicated that the drought period has increased. From the study it is concluded that climatic factors affect the development of plants not separately but integrated. The period with the greatest influence of ecological factors on the production of different genotypes of barley occurs in the months May – June, a period where the plant is in the ripening stage. The main factor identified, in terms of adaptation to climate change, is the planting of barley in October compared to March, applied in previous practices. Different barley genotypes manifest different degrees of response to climate changes.

Bean is one of the main legacy crops that play an important role in the planting structure of Korça region. Appreciating the bean as a rich food for man, the ancients have particularly been careful in the past to select and preserve the cultivars that have adapted to the ecological conditions of the country. This is evidenced by the large number of legumes planted or labeled according to the areas or villages where they have spread more. At present, this property poses a potential risk, the phenomenon of "genetic erosion". Farmers in the region use the zoned populations of beans. The study of these populations constitutes a necessity for the preservation of the autochthonous germoplasma of the beans as well as the competitive aspects and their spreading. The study revealed the germoplasma of autochthonous bean populations for the region of Korca.
