Release and Distribution of Lariat and Stampede Pinto Bean Seed
March 28, 2008
A short supply of Lariat and Stampede dry bean seed posed a bit of a challenge for the NDSU Research Foundation this year. But, according to Dale Williams, director of the NDSU Foundation Seedstocks Project, assistance from the North Dakota Dry Edible Bean Seed Growers Association (NDDEBSGA) along with the implementation of an allocation system, is helping move the process along.
Lariat and Stampede were released in early 2007, says Williams. But announcements were held off until July because no seed was available.
Williams explained that the NDSU Seed Foundation has guidelines in place to keep the seed allocation process as fair and equitable as possible.
Anyone who requests foundation seed by the first of December is considered, says Williams. However, if the requests exceed availability, then we have other guidelines that kick into place.
First, no one can receive more than 10 percent of the seed inventory. Second, people with a proven track record in producing seed under the certification program are given a priority. Thats because these people are judged as being able to get the seed out to the general producer the fastest, as opposed to people who may just produce seed for themselves, says Williams.
Allocations of Lariat and Stampede Seed
Because of all the excitement surrounding the release of Lariat and Stampede, the requests for seed on December 1 exceeded our inventory, says Williams. And not only that, but the majority of the requests were also from experienced certified seed producers.
Fortunately, Williams said the NDDEBSGA came forward with grant funding to help facilitate a winter increase of breeder seed in New Zealand during the winter of 2006-07 which was shipped back to the U.S. for foundation seed production in 2007. The additional seed generated by this effort is being allocated to seed growing members of the NDDEBSGA but the real benefit will be to regional commodity growers who will have access to more seed of these new varieties in 2009, says Williams.
By December 1, we had requests for nearly 300,000 pounds of Lariat seed, and only about 200,000 pounds available for distribution, says Williams. We were able to allocate NDDEBSGA members with about 87% of their requested seed, and non-members about 66%, so we did pretty good with Lariat.
With Stampede, there was a problem in shipping which resulted in some Stampede seed getting mixed with other bean seed, so we lost some, says Williams. We had requests for 283,100 pounds of Stampede, but only about 52,000 pounds of seed available. As a result, NDDEBSGA members only received about 21% of their requested amount, and non-members, about 16%.
Future Seed Availability
Williams says that registered seed of both Lariat and Stampede will be available next year, but points out that Stampede may be in somewhat short supply. But, he says more foundation seed will be available next year too.
Pinto Bean Response to Tillage Systems
By Greg Endres and Paul HendricksonA field study was conducted at the NDSU Carrington Research Extension Center to examine the performance of dry bean under several tillage systems. Experimental design was a randomized complete block with four replications. The previous crop was wheat. The dryland trial was established on a Heimdal loam soil with 3.2% organic matter and 6.9 pH. Conventional-till plots were tilled on October 16, 2006 using a roto-tiller at a 2-inch tillage depth. The fall strip-till treatment was applied on October 16 using a Yetter strip-till opener with 30-inch row spacing using a 4- to 5-inch tillage depth that established a berm about 10-inches wide. The spring strip-till treatment was applied on April 23, 2007 at a 5-inch tillage depth that established a berm about 12-inches wide. Conventional-till plots were tilled twice at a 3-inch depth using a field cultivator plus spring harrow on May 8. Maverick pinto bean was planted with a John Deere Max-Emerge II row crop planter in 30-inch rows on June 18. Conventional-till plots were cultivated between crop rows on July 6. Plots were prepared for harvest by hand pulling plants on October 3 to allow dry down. The seed was harvested with a plot combine on October 23.
Crop stand was low throughout the trial when measured on June 27, but fall strip till tended to have a greater stand compared to other tillage systems (See table below). Plant emergence (data not shown) and days to flower from planting were similar among tillage systems. However, conventional till reached physiological maturity two to three days earlier compared to other tillage. Seed yield was greater with fall strip till compared to other tillage. Test weight and seed size was similar among treatments.
