DOCUMENTING A FIFTH STAGE FOR CONTINUED GROWTH AND DEVELOPMENT IN DRY BEANS

摘要

A Fifth Stage for Growth and Development of Dry Beans - is Defined.Understanding the importance of Stage Five for Dry Beans comes from seventeen trials with eight Pinto (PT) and eight Great Northern (GN) Varieties from 2009-2017. Data from the Ag Lab weatto station [Scottsbluff 6NW, Period of Recor 1996-07-11 to-Present(AKA Mitchell Farms) Period of Record 1912 to 1996-07 11. Latitude 41.95N0. Longitude -103.70E00. Elevation 1254m. Client UN Extension - Panhandle] dating back to 19 was used in calculating Growing Degree Days (GDD) using the maximum temperature (Tmax)and minimum temperature (Tmin) for each day in the following formula:(GDD = (Tmax + Tmta/2) - T baSeof 50)Solar energy at any given location can be converted to GDD.The typical four stages of growth and development are well documented and are used with either Green Beans (GB) or Dry Beans (DB). Both warm-season crops depend upon solar energy in moving from one stage to another. Green Beans are harvested for their fleshy green pods and immature seed prior to stage four; in contrast, DB are harvested after stage four for their mature edible seed at 14% moisture. Maturity is recorded for DB when eight out of ten pods turn buckskin in color. The moisture of the seed inthe pod is about 30% at this time and about 30% of the leaves remain on the plant. Dry down of seed from 30% to the desired 14% moisture for harvest is longest if the plants are left standing or can be hastened by undercutting a furrow irrigated crop orby using a desiccant on a crop to be direct harvested.
