in most of the sugar beet cultivated areas including kermanshah, iran, late season irrigation is cut- off earlier than usual which causes drought stress in the crop. since root yield still increses in sept. and oct. these areas, withholding irrigation in this period reduce root yield and quality of sugar beet. for this reason, an experimente was conducted during 2004- 2005 based on split plot d...

The September and October (2013) wind storms in Canterbury, New Zealand had highest worldwide reported windstorm damaged on centre pivot irrigation systems. Around 800 centre pivot has been damaged and it cost farmers millions dollars directly and indirectly. It was very difficult to find the engineering proofed recommendation for farmers to protect their irrigation systems during windstorms. T...

The decline in groundwater supply the Texas High Plains is forcing some growers to convert center-pivot irrigated cropland dryland production. Transitioning toward reduced water input can lead declines soil health. We assessed short-term changes health indicators two transition scenarios: (a) from high irrigation method low (center pivot subsurface drip) and (b) dryland), comparison continuous ...
