Abstract:
Potatoes constitute the world’s main non-cereal food crop, ranking fourth behind rice, wheat, and maize. Potato (Solanum Tuberlosaum) is a very sensitive crop species to both temperature and rainfall. It does well in temperate cool climates with the optimum temperatures of 18 ⁰C and moderate rainfall that’s ranges between 850 mm to 1200 mm in a growing season and at altitude between 1400m and 3000m above the sea level. Climatic factors directly influence crop potential productivities, regulating its transpiration, photosynthesis, and respiration processes in such a way as to control the growth and development of the plants throughout their physiological cycle. Climate change and variability is one of the biggest challenges that the agriculture sector is facing today as it is the main determinant of the crop production. Impacts of climate change might be positive or negative. It has been seen that global warming has brought about a decrease in production due to changes in annual and seasonal rainfall, more erratic weather patterns and more intense and frequent extreme weather events such as heat waves, drought, storms and floods .This indicates mixed impact on potato production implying uncertainty and therefore need more research in different spatial and temporal over the Earth surface. Therefore knowledge of climatic requirements of potato and its physiological responses to the environment is extremely important to help growers produce high yields with good tuber quality under different atmospheric conditions.
