1Trial conducted at the Southwestern Colorado Research Center; seeded 6/10 and harvested 11/16.

2M =medium; L = late; VL = very late

 

Comments: 

The trial was planted on spring moldboard plowed alfalfa ground due to dry soil conditions that prevented fall plowing.  The ground was pre-irrigated to minimize clods and provide moisture for germination.  Slow growth characterized the trial in spite of the pre-irrigation and subsequent irrigations.  The trial was damaged by hail on July 23 which resulted in leaf loss and a subsequent delay in the maturity of the beans.  Row cultivation was delayed until August 1 to allow the beans to put on additional leaves.   A cooler than normal summer may have also delayed the maturity of the beans.

 

A second hail storm on Sept. 4 bruised the pods but did not result in any shattering of the beans.  The fall season was characterized by very wet weather which delayed harvest until Nov. 16.  Bean quality was damaged by the hail and the wet weather.  Yields were not adjusted for discolored beans since the ranking of the entries would not be significantly changed.  For comparison, a commercial field of pinto beans surrounding the trial had 6 – 8% discolored beans when delivered to the warehouse
