Dry Edible Bean Variety Trials
K. Cooper, L. Besemann and H. Eslinger
      Dry edible beans play a significant role in irrigated rotations in southeastern North Dakota.  As universities and private companies develop new varieties, it is important to test them upon their release. Seventeen edible bean varieties were tested: six miscellaneous, three navy, and eight pinto.
MATERIALS AND METHODS
Soil: Gardena loam sandy substratum, Embden sandy loam; pH = 7.1; 2.2% organic matter; soil N was 26 lbs/acre; soil P was high; soil K was very high and soil S was low. 
Previous crop: 2016 - Soybean.  
Seedbed preparation: Spring conventional tillage.
Planting: May 26 in 30-inch rows.
Plots: Plots were 25 ft long by 5 ft (2 rows) wide.  The study had four replications.
Fertilizer: Broadcast 21 lbs N/acre, 40 lbs P2O5/acre, 50 lbs K2O/acre and 15 lbs S/acre as 10-18-23-7 April 4.
Irrigation: Overhead sprinkler irrigation as needed.
Pest control: Authority 19 oz/acre (May 19), Select 16 oz/acre + NIS 1 pt/100 gal + Interlock 4 oz/acre (June 20) for weed control.  Endura 5.5 oz/acre (July 20) for disease control.
Harvest: Hand harvested bean varieties September 11 to September 12 as they matured.  Harvest area for all bean varieties was five feet (two rows wide) by approximately 19 feet. Beans were threshed with a stationary plot thresher September 14.
RESULTS
       The three classes of dry edible beans all had good yields for the 2017 season. The mean yield of the miscellaneous beans was 4223 lbs/acre.  Zorro (black bean) had the highest yield of the miscellaneous beans yielding 4827 lbs/acre. The mean yield of the navy beans was 3552 lbs/acre.  HMS Medalist had the highest yield of the navy bean yielding 3872 lbs/acre.  The mean yield of the pinto beans was 3932 lbs/acre.  LaPaz had the highest pinto bean yield at 4249 lbs/acre.
