We see, hear, experience, how difficult this is. But we adapt as quick as we could to continue our respective roles. We show here some of the virtual field day content. Below are only the forage component of the virtual field day in 2020.
It is time to update contents of this blog through photos as they depict thousands of words. Recently, I accepted an additional 25% administration appointment as an interim superintendent of the research center while improving my research and other responsibilities such as outreach and service to the Crop Science Society of America and Agronomy Society of America, Montana State University, etc.
Below is a fraction of the inquiries focusing on genetic-specific resource efficiency studies. We manage a total of sixteen field-type research this year. We learned to plan and work as efficiently as possible as a team and kept our cool.
Producers in NW Montana have revisited and planted growing Soft White Spring Wheat in lieu of Hard Red Spring Wheat for economic reason. Last year (2015), other than the NW MT extreme drought that occurred, the price of hard red spring wheat dropped and soft white market price was higher. Thus, some producers have opted planting this market class this year. Though, this market class is prone to pre-harvest sprout and falling number at the elevator can be a real downer. There are strategies in terms of limiting irrigation water towards late seed-fill, etc. as discussed during this year’s winter grower meeting.
Soft white wheat is a low moisture wheat ideally used for asian-style noodles, pastries and flat breads. Low protein is desired for this market class and a high protein soft white is discounted at the elevator.
This year, we study management options to focus on yield increase and not on protein. The rationale was discussed during our July 12, 2016 field day and we look forward to provide you with updates during our winter grower meeting in Kalispell, MT. See you there.
This spring has been dry. Most conversations at garden and grocery stores have been, “Where is the rain?”. A great excuse to talk about the weather to either vent on how dry it is or to simply start a ‘plain’ conversation.
While some US States are flooded, in Montana we ask the above question. The photo below is a view from NWARC with snow-free mountain peaks. Definitely, last year was a different story.
This year, Kent McVay, Paul Stoy, and myself, went ahead and submitted a grant proposal to Montana Wheat and Barley Committee to validate crop coefficients (Kc) to better irrigation scheduling. Kc is crop specific and varies during the course of the growing season. It is used to estimate crop water use, or transpiration (partially), or engineers/scientists call it crop evapotranspiration (ETc). It is a multiplicand to the reference evapotranspiration (ETo) in order to estimate ETc (ETc = ETo x Kc).
We used Eddy Covariance tower that measures water and carbon fluxes. Installed in spring wheat (Creston) and in barley (Billings). Eddy is termed after transport of Eddies (or turbulent eddies or air
movements). Eddies that are in contact with the surface of a plant or canopy can pick up water vapor or sensible heat used to measure surface water loss, referred as evapotranspiration.
EC Tower installed on May 15, 2015 in farmer’s spring wheat field. Thank you James for your technical expertise in the installation/programming, and Paul Stoy for these towers.
The NWARC field day will be in June 24, 2015. I will be discussing primarily on irrigation practices for spring wheat, plus, the EC Tower that you might have seen as you drive closer to NWARC along MT 35.
Where is the rain? I still ask that question. On a good note, it will be good for irrigation research and how various spring wheat varieties respond to various irrigation strategies towards improved recommendations on water management x spring wheat varieties for yield and quality.
On May 29, 2015, irrigation was triggered for spring wheat that was planted on April 22 on a fine sandy loam soil. Plants here have 4-5 leaves and are tillering – the stage where crop water requirement increases. In the photo is Marcelle Tikka- research assistant, inspecting the drip irrigation timer. The blue monitor is logging soil water depletion in centibars [Irrometer, Inc] to complement soil-water-balance approach.
A view of the water use efficiency studies in fine sandy loam and silt loam soils.
Thank you Montana Wheat and Barley Committee for funding another year to this irrigation study.
