Abstract

Attention to agricultural production capabilities in every region is related to climatic characteristics, so study on the climatic parameters is very important. This study evaluates for assessment the effect of wind on crop conditions and optimizes the amount of crop conditions by wind break on wheat in Mohammad Abad in Esfahan. For assessment of changes that are resulting from carminative agronomic Traits of Wheat include: grain weight, number of grains per spike, spikes per square meter, grain yield, biological yield and percentage resting form a complete random design treatments. Distance carminative height was evaluated. Analysis of variance showed significant difference in the level of 1 percent for grain weight, yield and resting percent and 5 percent levels for biological yield and grain number per spike showed. Test to compare mean grain weight, number of grains per spike, spike in m², grain yield, biological yield and percentage resting treatments at different levels indicated significant differences in the averages of each trait in each treatment. Test results compare mean grain weight, number of grains per spike and grain yield indicate a trend similar to the distance from carminative are interactively with increasing distance from the windbreak to 5 times the height of all traits increase. So that significant differences between their control and this is evident from the values of these traits point to reach their maximum and then with increasing amounts of their distance decreases and amounts to 15 times the height of the traits seen carminative without significant difference. For the adjective percentage resting contrast crop plant performance has done so, these traits also influenced by distance are carminative. But the spike in m² and biological function are not affected of distance from the windbreak
