1. Differences in How Late Season Soil Vs. Foliar Nitrogen Fertilizer Supplements Affects Riesling YanDuring the 2011 and 2012 growing seasons, 0, 15, or 30 lbs/A N was applied in split applications as either soil (simulated drip) or foliar applications to a commercial Riesling vineyard with a history of low vine N. Each treatment was replicated 4 times. To assess the impact of the supplemental N applications on vine vigor, shoot lengths were measured weekly and pruning weights collected during the dormant season (2012/2013 pruning not yet conducted). Fruit was harvested within 2 days of commercial... J. Davenport, M. Mccoy |
2. Siderophores to Increase Iron AvailabilitySiderophores are biologically produced low molecular weight amino acids that act to chelate metals. These can be generated by soil microorganisms and some plants, most notably grasses, also produce siderophores. These compounds are associated with improved availability of iron in the soil. This manuscript presents a survey of microbial siderophores present in soils under chlorotic and non- chlorotic ‘Concord’ grapevines. ... J. Davenport, A. Pollard, T. Sullivan |
3. Floral Hemp Responses to Nitrogen Fertilization in the High DesertThe performance of floral hemp under N fertilization is influenced by environmental conditions, management and cultivar selection. This field study evaluated the effect of no supplemental N and N fertilization at 90 kg ha-1 on three hemp cultivars (Berry Blossom, Red Bordeaux, and Tahoe Cinco) in Northern Nevada. Nitrogen increased plant height, canopy cover, stem diameter and shoot biomass, but other physiological parameters were dependent on cultivar. We evaluated the use... F. Barrios masias, M.
