Non-point source pollution is considered as a serious issue especially in the field of eutrophication for surface waters. Vegetative buffer strips include a specific plant being passed by flow before entering the waterways, so it causes to reduce runoff volume, deposited pesticides and other pollutants of the flow through infiltration, absorption and sediment deposition. The present study has b...

In most wheat growing moderate regions and especially in the north of Iran climate, is affected grain filling by several physical and abiotic stresses. In this region, grain filling often occurs when temperatures are increasing and moisture supply is decreasing. The experiment was designed in RCBD with split plot arrangements with four replications. Four irrigation treatments included (I0) no i...
