Monitoring soil nitrate to estimate cover crop nitrogen contribution

Creator:: Andrews, Nicholas, Sullivan, Dan M., and Pool, Kristin
Abstract:: Organic vegetable growers rely on legume cover crops as an economical source of plant-available N. This research evaluated N contributions to summer vegetable crops by cover crops (CC) residues by monitoring soil nitrate (NO3-N) concentrations during the summer crop growing season. Replicated field plots were established with three CC mixes:...

Refining nitrogen management for organic broccoli production

Creator:: Sullivan, Dan M., Peachey, Ed, and Donaldson, Andrew
Abstract:: Specialty organic fertilizers used in organic vegetable production are expensive. So, from environmental and economic perspectives, growers want to maximize nitrogen (N) fertilizer use efficiency by the crop. This research was conducted to (1) determine sufficient N fertilizer rates for organic broccoli, (2) evaluate the efficacy of a specialty organic...

Measuring ammonia loss using field-scale and laboratory techniques

Creator:: Heinrich, Aaron and Sullivan, Dan M.
Abstract:: Following the surface application of urea to soil, there is the potential for nitrogen (N) loss from ammonia (NH3) volatilization until sufficient rain or irrigation has moved it into the soil. Many studies measuring NH3 loss have used laboratory and microplot field studies. The limitation of these techniques is that...

Tolpyralate Efficacy and Utility in Sweet Corn and other Vegetable Crops

Creator:: Peachey, Ed
Abstract:: Presented at the 70th Annual Meeting of the Western Society of Weed Science.
Resource Type:: Presentation

Identifying breeder-friendly INDELs that co-seggregate with SNPs associated with QTL for resistance to Fusarium solani root rot in snap bean (Phaselous vulgaris)

Creator:: Schmidt, Joseph A.
Abstract:: Fusarium solani is a chronic disease that causes root rot which affects bean production worldwide. Recently, a QTL map was generated which identified several SNPs which were found to be associated with resistance to the pathogen. To be useful in a breeding program, INDELs must be identified which co-seggregate with...
