Water Efficiency for Urban Landscapes in Semi-Arid Environments

Creator:: Martinson, Richard W.
Abstract:: Urban landscape water use is increasingly a focus of water conservation efforts. This is especially true in the arid and semi-arid regions of the western United States where increased demand, environmental concerns, and extended periods of drought have created chronic water shortages. However, until recently, little attention has been paid...

Effects of irrigation scheduling, using remotely sensed canopy-air temperature differentials, on water relations, yield, and quality of snap beans (Phaseolus vulgaris L.)

Creator:: Bonanno, A. Richard
Abstract:: Field experiments were conducted in 1981 and 1982 to develop a method for using remotely measured leaf canopy-air temperature differences (stress-degree-days (SDD)) to schedule irrigations and to evaluate the effects of differential irrigation on snap bean cultivars, 'Oregon 1604' and 'Galamor'. Effects on soil water potential (SWP), leaf water potential...

Factors affecting survival and vigor of cold-stored strawberry nursery stock

Creator:: Decker, Bruce Richard
Abstract:: Field survivals of strawberry (Fragaria x ananassa) runner plants dug from December to April in both 1979 and 1980 were above 9C% when planted about May 1. When plants from the same digging dates were planted in early June, survival of March-dug 'Olympus' declined to 88% and survival of late-April-dug...

Breeding Snap Beans for Organic Agriculture: Genomic Shifts under Different Agricultural Management Systems

Creator:: King, Ryan M.
Abstract:: Although the concept of breeding crops for organic agricultural systems has been around for decades, few studies have been reported for vegetable crops to quantify and compare how conventional and organic systems differ in their selection pressures on genotypes advancing through the breeding cycle; especially research utilizing modern sequencing capabilities....

Annual bluegrass (Poa annua L.) control with ethofumesate during turfgrass establishment

Creator:: Wieneche, David L.
Abstract:: Temperate climates are particularly conducive to growth of annual bluegrass which readily invades and dominates most cool-season turfgrasses. Ethofumesate (2-ethoxy-2,3-dihydro-3,3-dimethyl-5-benzofuranyl methanesulfonate) is one herbicide available which will selectively control annual bluegrass. The primary objectives of this research were to determine optimum application rates and timing of ethofumesate for control of...

The influence of increased base saturation and the chloride ion on Fragaria ananassa, Bailey

Creator:: Lyons, Calvin G.
Abstract:: Research was carried out to determine the influence of increasing the percentage base saturation of the soil on the yield of the commercial strawberry. It was found that the effect of increasing the bases in the soils was directly related to the original percentage base saturation. When this original value...

Needs Assessment for Future US Pear Rootstock Research Directions Based on the Current State of Pear Production and Rootstock Research

Creator:: Elkins, Rachel B., Bell, Richard, and Einhorn, Todd
Abstract:: The area devoted to pear production in the United States (U.S.) is declining due to lack of precocity and high cost of production. The U.S. pear industry currently lacks "modern" orchard systems characterized by compact trees that produce early, high yields of large, high quality fruit. Tall, shaded canopies are...
