Properly harvested and stored, corn silage is extremely palatable, superior to other forages in energy content, a great fiber source, and relatively consistent in quality. The high palatability of corn silage encourages feed intake which contributes to hi

Valley pocket gophers (Thomomys bottae) are a common agricultural pest in many areas of Utah, Nevada and California. Pocket gophers predominantly eat roots, although they will pull vegetation into their burrows, and eat plants immediately adjacent to thei

The importance of rotating out of a declining alfalfa stand is well established. As the alfalfa stand ages, forage yield and quality decline, while weed, insect, and disease pressures increase.

In Utah, there are typically three generations of corn earworm (CEW) each year. The first generation of adults either come from overwintering pupae (southern and central Utah) or migrate into northern Utah. The adult moth is tannish brown with a 1 1/2 inc

This report summarizes on-farm performance of irrigated silage corn hybrids at Benson (Cache County) in 2006. The site is at 4439 ft elevation and has a long-term average of 2800 corn growing degree days (50/86° F) per year. Hybrids were seeded with a six

As water demand and scarcity increase simultaneously over the coming decades, water managers and growers will need to optimize water use on their irrigated lands. These challenges have been especially noticeable as the Western U.S.faces a prolonged “megad

The purpose of this fact sheet is to provide the current state of knowledge on cover crop management for Utah based on USU research and local grower experience.

Size and scope and crop production costs and returns for counties in Utah.

Crop Revenue Coverage(CRC), provides revenue protection against a yield loss, a price decline, or a combination of both. CRC is available for these crop and counties Beaver, Box Elder, Cache, Carbon, Davis, Duchesne, Emery, Garfield, Iron, Juab, Millard,

Utah’s climate can often be harsh and unpredictable. As the nation’s second driest state, Utah is commonly subject to droughts. Extensive statewide droughts have often lasted 5 to 6 years. It is imperative that farmers are well prepared to defend against

Deficit irrigation is any irrigation level that does not meet the crop’s full evapotranspiration (ET) demand, meaning evaporation from plant and soil surface and transpiration through plant growth.

Environmental concerns over nitrate contamination of ground water, and the desire of land managers to increase the efficiency of their fertilizer investment, can both be satisfied more completely through diagnostic testing for nitrogen (N) soil fertility.

Downy mildew is an obligate parasite. Even though they look like fungi they are not. They belong to the Oomycota and are more closely related to algae than true fungi. The most common alfalfa downy mildew species in the USA is Peronospora trifoliorum. In

The disease first appeared in Utah in the early 1930s in Cache County near the city of Paradise. The disease was soon found in Box Elder County near Hansel Valley. The outbreak of dwarf bunt became so severe that it affected other crops, such as barley.

If sprayers are not properly calibrated, it can result in over or under-application of chemicals, causing damage, reduced pest control, and potential safety concerns. Making the effort to properly mix chemicals and calibrate sprayers can save money and in

Irrigation canals placed in native soil or lined with earth can have seepage water losses varying from 20 percent to more than 50 percent. Well designed, new compacted earth lined canals can have reduced seepage losses similar to concrete lined channels.

When deciding which irrigation systems to adopt, permit, or promote, it is important to consider how their efficiency and losses affect the water balance of Utah’s watersheds and drainage basins. Irrigators have no control over precipitation and only limi
