بررسی اثر روشهای مختلف خاک ورزی فصل آیش در ذخیره رطوبت و عملکرد گندم دیم رقم آذر 2

In order to study the effects of different tillage methods on the grain yield Wheat (Azare 2) and soil physical properties in dryland conditions an experiment on the base of split plot arragment out in korromabod agricultural station duriny 2004-2007. Treatments for mainplots are as moldboard , ) semi moldboard , chizel and minimum tillage and subplots are : sweep and rotivator Treatment were replicated 3 times.wheat was uniformly (Azare 2) planted in all of plots and necessary farming practices were applied in rainfed and soil moisture . the results of analysis of variance showed that soil cultivating methods signicficantly ( )= %1) and the treatment increased wheat grain yeild and strow 1 oblined the P ha highest on grain wheat or strow step by step 2091 , 4523 . kg -No significant intraction between main plots and subplots about year and grain yield .seed Weight bulk dancity , soil moisuture and organic material were found respectively . - No signicficant istatical effect were found between fallow management methods and soil moisuture (0-30 cm) and bulk dancity. - the effect of soil fallowing methods and organic matters in soil was signicficanted as some results from this study the effects of subplots fuetar and grain yeild ( 0.01) ha sweep treatment with 1991 and 4065 ( 0.01) and strow was signicficant at kg grain yeild and staill matarial was superior to other treats . - the effects of subplots an grain yield , bulk dancity and soil moisuture at (0-30 cm) . ( 0.01)were signicficant at ( 0.05) - the effects of subplots treats were signicfican and soil organic matters at
