Nitrogen (N) management in small grains has recently managed to capture more attention than usual due to the high cost of N fertilizers. Several researchers from UC and UCCE have been working on projects that can provide growers with some valuable information on various N management options.
Join us next month (Tuesday April 18, 2023, previously March 22, 2023, rescheduled due to wet field conditions) from 8:40 until 10:30 for some quick updates on research. The field site is an experimental trial run by Cameron Pittelkow evaluating the use of digestate and hydrolysate as a N source in small grains.

Long dry periods are not uncommon in the Sacramento Valley between January and February. Despite the early season downpours, rainfall for the 2021-22 water year is dropping back to below average (Figure 1), and there is no rain on the near-term horizon. As a result, wheat growers may be debating whether to irrigate. Here are a few things to keep in mind:
Stress during the rapid growth phases can reduce wheat yield substantially
The amount of water needed to avoid plant stress at early vegetative growth stages is relatively little compared to later in the season (Table 1, see:

Summary Note
Mechanical cultivation is a useful tool in controlling herbicide-resistant Italian ryegrass individuals in a rainfed wheat system but is only about half as effective as Axial in reducing overall pressure from Italian ryegrass (expressed as a percentage of total groundcover). Growers should consider multiple approaches (chemical and mechanical) and integrate IPM strategies to reduce the spread of resistance among Italian ryegrass individuals.
Background
Italian ryegrass (Lolium multiflorum) has been shown to be a persistent weed for growers in rainfed winter grass systems. It is particularly problematic due to its...
