Cucumber Cropping Systems: Impacts on Weeds, Yield and Fruit Quality Ohio GLVWG Feb 24, 2005 Mathieu Ngouajio
2003 production in 1000 tons 2003 U.S. acreage: 119,000 A Total Value: $178 million
oWide row spacing is one of the strategies proposed for management of Phytophthora in pickles Wide rows oDecrease relative humidity within the plant canopy oAllow the soil to dry faster oLow plant Population oLow Yield?

Source: Crop profiles mainly
Row spacing varies: From State to State From grower to grower within a State Rows are: Narrower for machine harvest Wider for hand pick cucumbers oLow plant Population oLow Yield?
Is it possible to increase row spacing (reduce populations) and maintain acceptable yield and fruit quality?
