The beta version of an interactive webtool for California small grain variety selection is now available on the Small Grains portion of the UC Agronomy Research and Information Center Website:
The tool is designed to help users pinpoint small grain varieties that have performed well in particular regions and environments of California using data from multi-year, multi-location field trials. The main features of the tool are a series of selection menus that interact with a map to give...
Results from the 2016-2017 Fall-planted small grain variety trials throughout California are now available. These include tests of commercial and advanced varieties of common wheat, durum wheat, triticale, and barley, with multi-year productivity, disease and agronomic traits summaries included as well as single-site summaries from all Fall-planted 2017 trials. Results are available on the UC Agronomy Research and Information Center (AgRIC) Small Grains website:

Recent UCCE research has illustrated the value of in-season applications of nitrogen (N) fertilizer, particularly applications made at the early vegetative growth stages. This is typically the stage of growth when N demand from the crop is increasing rapidly, the soil is beginning to warm up, and microbial metabolism and associated mineralization/transformations of the various forms of N are increasing. Over a wide range of California conditions and across multiple seasons, applications of N fertilizer at this stage of growth have been shown to
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:
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 quality...
As noted during our May 11th Field Day presentation in Davis, during the 2016-17 season darkening/purpling glumes (as depicted in Image 1) were widely observed in common spring wheat both within the UC Regional testing program and by growers and crop consultants around the San Joaquin and Sacramento Valleys. In addition, these symptoms appeared to have a genetic link because particular wheat varieties consistently displayed symptoms in multiple locations, while others displayed none.
There are multiple potential causes for darkened glumes, some pathogenic and some physiological. Cassandra Swett, the UC Cooperative...
