Outline• Research completed
– Cover crops variety trial at two seeding dates ( N and P uptake)– Timing of winter rye removal for weed control in soybeans.– Corn-alfalfa intercropping: alfalfa as a cover crop in corn– Short-Term Soil Responses to Late-Seeded Cover Crops in a Semi-
Arid Environment– 2015 Cowpea Variety Trial Prosper North Dakota
• Research in progress– PDP SARE Enhancing Soil Health with Cover Crops in North Dakota:
Training Program. – Adaptation of cover crops to build soil health in the northern Plains NCR-
SARE, on farm-research demonstration and educational. – Nutrient cycling ability of forage radish and turnip previous to corn and
soybean– Winter Rye Research at the CREC - Using winter rye as a forage crop.
Cover crops variety trial at two seeding dates
• Planting dates were July 21 and August 20, 2015.
• The first date include 16 cool- and warm-season cover crops)
• the second date only 14 cool-seasons. • Biomass, N, and P uptake were calculated
Date 1Forage sorghum and forage triticale 2.59 and 4.97 tons/acre dry matter
Date 2Rape Dwarf Essex and radish Daikon 1.47 and 1.47 tons/acre
Scavenging- N and P uptake
N and P uptake
Timing of winter rye removal for weed control in soybeans
• Soybean growth and development was not reduced by rye through 16 June, rye at anthesis and soybean, first true leaves.
• Rye reduced kochia growth and vigor, but not necessarily reduced plant numbers
• The weed suppression of rye disappeared once the rye began the senescence process and the canopy opened up.
• Stunted kochia resume growth.• Mid-August, rye variety lost most of its effectiveness on kochia
Sprayed at anthesisHarvested as forage at anthesis
No rye check
Research/activities in progressPDP-SARE Enhancing Soil Health with Cover Crops in North Dakota: Training Program
Adaptation of cover crops to build soil health in the northern Plains NCR-SARE, on farm-research demonstrationReached over 500 farmers, county agents,
college students, and consultants- 7 table talks, Cafe talks, workshops- 5 field days or plot tours
