Abstract :
The experiment, is based on the standard scenarios, loaders case IPCC (B1, A2, A1B) by general circulation model (HadCM3) with the use of fine scale model (LARS-WG) with the aim to evaluate the effect of climate change on the phonological stages answer C3 plants, in research farm of agricultural college of Lorestan University in cropping years 2014-15 and 2015-16 With, in two consecutive years and rain fed conditions was conducted in one place. Complementary components of intercropping of broad leaf vetch and barley in 5 levels, weeds and compost as well as four levels, respectively. in 4×5 factorial experiment with in a randomized complete block design was used for the target year 2055 AD (1445 Shamsi) in dry land conditions. Climatic factors as temperature, precipitation and daily radiation in period of study with simulation used LARS-WG modeling. Thus, min and max temperature oscillation in the future desirable for growth of C3 plants (broad leaf vetch and barley). Also, average precipitation is slightly more and will reduce the length of the period of growth and failure to deal with the above optimal temperatures and drought stress and escape from the end of the season due to being the period in accordance with growing season, reduce the risk of environmental hazards in the upcoming years due to performance and stability have been achieved fitted.
