Small grains are planted for a variety of reasons, but their rotational benefit makes them a popular crop all over the world and influences the way they are planted. One of the major benefits of small grains as rotational crops is that they cover the soil and suppress weeds
Karnal bunt is a disease of wheat, durum, and triticale caused by the fungal pathogen Tilletia indica Mitra. Karnal bunt was first reported in India in 1931. This article discusses it's cycle, symptoms, and suggestions on how to control it.
Planting at the optimum time is probably the most important cultural practice in producing high small grain yields. Wheat and barley crops that are planted too early or too late have lower yield potential no matter how they are grown after planting. Some suggestions on planting dates are outlined in this article.
The most important disease of woody dicotyledonous plants in Arizona is Phymatotrichopsis root rot (Cotton or Texas root rot) caused by a unique and widely distributed soil-borne fungus, Phymatotrichopsis omnivora. This article talks about the diseases distribution, symptoms/signs, biology, identification, sampling, and control.
Genetic Diversity and Fungicide Sensitivity of Phymatotrichopsis omnivora
Cotton root rot, caused by Phymatotrichopsis omnivora, is the most destructive disease of dicotyledonous plants in Arizona. There are no known reliable control methods for this disease, and the difficulty in its management is most often directed at its survival deep in soils and its wide host range. Genetic diversity in P. omnivora and its potential role in disease are unknown. Isolating the fungus and reproducing the disease in the greenhouse or laboratory are problematic, making it difficult to assess the efficacy of potential treatments.
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.
Small Grains Variety Evaluation at Arizona City, Maricopa and Yuma
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.
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.
Sensor-based management of Nitrogen of irrigated durum wheat in Arizona

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.
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.
