The heavy rains have stopped a lot of growers from getting into their wheat fields, and growers may be wondering what the best move is given the break in the weather. Our forecast for rain in the next 10 days looks spotty, and that has some implications for both nitrogen and herbicide management in small grains.
Nitrogen (N) management.
Studies and experience indicate that in-season applications of N provide a much better response to fertilizer than preseason applications. In years such as this, that is more likely the case because heavy early-season rainfall reduces the amount of plant available N in the root zone. Growers may be...

UC Cooperative Extension will be hosting two field days this month that may be of interest to rotational crop growers who work with small grains. Full agendas are pending, but mark your calendars in the meantime.
1) Thursday, April 21st: Controlling Italian ryegrass in Small Grains: Join us for a series of short presentations on different methods of control for Italian ryegrass. Speakers will include industry representatives and UC researchers. Participants will also have opportunity to observe this year's herbicide trial on-site, which will exhibit the efficacy of several available chemical controls and several different tank mixtures. Discussions will also cover alternative methods for control and...

Join us from 9 a.m.- 10 a.m. on Wednesday, September 29th for a short online demonstration/webinar on several powerful nitrogen management webtools that have been developed by UC researchers, including case studies from this year in the Sacramento Valley.
This webinar is free of charge and open to the public.

Much like other parts of California, the Southern Sacramento Valley has seen some substantial rainstorms this season. The weather patterns left growers with a few narrow planting windows spread out over the last two months. This combined with the fact that growing degree day accumulation has been steeper than average (largely due to warmer nights) means that wheat growth stage can vary significantly from one field to the next. Now would be a good time to assess wheat stand, weed pressure, sample for soil nitrate levels, and start planning for nitrogen applications as fields enter the tillering phase of development.
As has been discussed in previous blog posts, nitrogen applications are most efficient when
