The University of Idaho
College of Agricultural and Life Sciences recently released
two new publications for potato growers-one on producing
potatoes with limited water supply and a second on nutrient
management guidelines for Russet Burbanks.
The eight-page publication "Potato
Production with Limited Water Supply" discusses the
impacts of water stress on potatoes at various growth stages
and presents strategies growers can consider if they expect
water to be short. Authors Bradley King, Jeffrey Stark and
Stephen Love describe deficit irrigation management and
review such options as reducing potato acreage, selecting
fields whose soils have higher water-holding capacities,
planting aged seed and increasing seedpiece spacing. They
also provide irrigation management tips for such
early-maturing or drought-tolerant varieties as Ranger
Russet, Russet Norkotah, Shepody, Alturas, Gem Russet,
GemStar Russet and CalWhite.
The 12-page publication "Nutrient
Management Guidelines for Russet Burbank Potatoes"-written
by Stark, Dale Westermann and Bryan Hopkins-advises growers
on methods of optimizing fertilizer-use efficiency. It
covers factors affecting potato nutrient requirements, soil
and plant analyses, fertilizer application methods, and
management of nitrogen, phosphorus, potassium, sulfur,
calcium, magnesium and micronutrients.
