Irrigation Criteria for Drip-irrigated Onions
Long-day onion (Allium cepa L. 'Vision') was subjected to five soil water potential (SWP) treatments (-10, -20, -30, -50, and -70 kPa) using subsurface drip irrigation in 1997 and 1998. Onions were
Review Of The Sugar End Disorder In Potato (Solanum tuberosum, L.)
TLDR
This review summarizes sugar end investigations to-date, and presents a list of research-based crop management recommendations that assist potato producers in minimizing the potential for sugar end development in the field.
Infrared Thermometry and the Crop Water Stress Index. I. History, Theory, and Baselines
Development of portable infrared thermometers and the definition of the Crop Water Stress Index (CWSI) have led to widespread interest in infrared thermometry to monitor water stress and schedule
Impact of early-season water deficits on Russet Burbank plant development, tuber yield and quality
TLDR
Russet Burbank potatoes grown on Owyhee silt loam were subjected to early-season moisture stress by delaying initiation of furrow irrigation up to seven weeks after planting, associated with declining total yield in 1985 but not in 1986.
Effects of transitory water stress on potato tuber stem-end reducing sugar and fry color
TLDR
The effect of imposed water stress on tuber stem-end reducing sugar concentrations was most pronounced post harvest, and decreased soil water potential (drier soil) was associated with progressively darker fry colors at harvest and post harvest.
The effect of timed water stress on quality, total solids and reducing sugar content of potatoes
Potato (Solanum tuberosum L.) solids and reducing sugars were examined before, just after, and two weeks after transient water stress to gain an understanding of tuber changes that occur directly
Infrared thermometry and the crop water stress index. II : sampling procedures and interpretation
Infrared thermometry can be a valuable research and production tool for detecting and quantifying water stress in plants, as shown by a large volume of published research. Users of infrared
Plant Population and Nitrogen Fertilization for Subsurface Drip-irrigated Onion
Onion (Allium cepa L.) production in the Treasure Valley of eastern Oregon and southwestern Idaho has been based on furrow irrigation with 318 kg·ha -1 N fertilizer and average yields of 70 Mg·ha -1
