The Study of Most Important Climatic Parameters Influencing on Potato Yield with Climate Change Paradigm (Studied Case, in Kermanshah Province)
Journal Title: International journal of Advanced Biological and Biomedical Research - Year 2014, Vol 2, Issue 1
Abstract
Climate change is one of the most important challenges in recent years. Heavy flood, hot weather, early coldness, most of drought replications, risen of sea water level, pests and plant disease ,reducing of ozone layer thickness, global worming ,and melting ices, are cases that introduced climate change issue in recent decades more. Climate is one of the most important factors for crop changing rate and its yield in recent decades .in regard to that potato is one of the most important agricultural crops in country ,and almost is planted in most areas, in this survey we have considered to studying temperature impacts and fall raining and its shifts as most important parameter influencing on potato yield in Kermanshah province. Because of this reason , cities having acceptable agricultural and climatic statistics are chosen.(6 cases )and then in regarding to phonological cycles of potato and agricultural calendar , the climatic parameters are divided to 6 variants. According to different climatic characteristic in Kermanshah, in GIS environment and using of zonal statistic capacity of this software ,statistical characteristics of production yield and other variants are derived based on classifying climate and finally in SPSS software ,most important climatic parameters influencing on yield and also changes trend is measured in all of Kermanshah province .results showed that temperature of ending winter and early spring were important parameters influencing on potato yield in most areas in Kermanshah province. And if these temperature is increased , yield rate of potato is increased in most areas in Kermanshah.
