After a relatively dry start to the rainfall season from October through early November, rainfall in California since November has been above average. About halfway through the rainy season, year-to-date precipitation totals are approximately 20-30% greater than the 10-year average in the small grain growing regions of California (Figure 1).

 Growing degree days (GDD: 86F max; 45F min) for common wheat and other small grains have been accumulating more rapidly than the 10-year average since the middle of November (Figure 2), which has been primarily a function of warmer than average night-time temperatures (Figure 3).

Results from all fall-planted 2017-2018 UC Statewide Small Grain Variety Testing Program trials are now available on the UC Small Grains website: http://smallgrains.ucanr.edu/Variety/.

These include fall-planted common wheat, durum wheat, triticale and barley trials in Sacramento Valley, San Joaquin Valley and Imperial Valley locations, and fall-planted winter wheat trials in the Intermountain Region. Results can be accessed as multi-year, multi-site summaries or site-specific summaries on...

The most up-to-date results from the 2017-18 UC Small Grain Variety Testing Program trials as well as trials from previous seasons can be found at the UC Agronomy Research and Information Center Small Grains websites. There are two interactive sites now available to explore UC small grain trial data.

The first site (http://smallgrainselection.plantsciences.ucdavis.edu/) produces regional summaries based on 3 years of trial data using statistical techniques that account for incomplete/unbalanced data across multi-season/multi-location trials. These multi-environment summaries are what we recommend using for...

Preliminary grain yield results for our fall-planted common wheat, triticale, durum wheat and barley trials are now available on the UC Small Grains Research and Information Center website:

http://smallgrains.ucanr.edu/Variety/Preliminary_2018_Yield_Results/

The results are preliminary and may change as samples are cleaned, processed for quality and corrected for minor variations in moisture content. Final results that include disease and agronomic observations and grain...
