Small grain varieties are evaluated each year by University of Arizona personnel. The purpose of these tests is to characterize varieties in terms of yield and other attributes. This article describes the procedure.
Research Report Effect of Planting Date on Wheat Yield in Yuma
Planting dates are known to affect wheat yields. Previous research has shown that the optimum planting date in Yuma is December 15 to January 15. This research paper tested six different planting dates with a wide range of varieties of wheat.
This article describes the sweetpotato whitefly (SWF) in great depth and their relation to Desert Vegetables and Melons. It includes it's history of development and damages it has caused. The article also describes the management of SWF, including sampling/monitoring, natural/biological control, cultural practices, and insecticidal control.

Arizona grows approximately 10% of the nation’s cauliflower. Most of the cauliflower grown in Arizona is grown in Yuma County. As with most crops grown in Arizona, irrigation plays an important role in determining crop yield and quality. This is especially true for vegetable crops such as cauliflower where water stress can translate to poor yields (tonnage) or poor quality (firmness, head size, color).
Methods of Measuring for Irrigation Scheduling - When
Proper irrigation management requires that growers assess their irrigation needs by taking measurements of various physical parameters. Some use sophisticated equipment while others use tried and true common sense approaches. Whichever method used, each has merits and limitations. In developing any irrigation management strategy, two questions are common: “When do I irrigate?” and “How much do I apply?” This bulletin deals with the WHEN.
2014 Management of Whiteflies and CYSDV on Fall Melons
CYSDV has caused significant reductions in fruit yields in the past, mainly due to the whitefly. This article gives some management guidelines for the whitefly including cultural management and chemical management.
Impact of Bagrada Bug Infestations on Desert Cole Crops, 2010-2013
The bagrada bug became a major pest of cole crops since 2010. This report consists of information gathered through surveys over five years and shows what some of the trends are regarding the bagrada bug over that time period.
Determination of optimal planting configuration of low input and organic barley and wheat production in Arizona
Markets for organic barley and wheat are expanding. A major problem growing organic barley and wheat is controlling the weeds. This paper outlines a study of growing organic barley documenting the weed pressures.
Sensor-based management of Nitrogen of irrigated durum wheat in Arizona
Authors: Pedro Andrade-Sanchez and Michael J. Ottman
It can be difficult to accurately apply the proper amount of nutrients to wheat due to their varying sizes and densities. Current field equipment can already vary the rate of fertilizer dispersal, but it needs to be controlled by an algorithm. An algorithm is being developed for that purpose.
