1. Cover Crops in Certified Organic, Specialty Crop Food ProductionThere is a growing interest in certified organic, specialty crop food production. With a larger population demanding organic products and organic products offering a higher premium for the producer, farmers are exploring the transition to organic farming. Organic producers in southeastern Wyoming face multiple challenges in environments with high elevation, low precipitation, and have a short growing season. These challenges include management of persistent weeds, maintaining biodiversity, and... E. Moore, U. Norton |
2. Effect of Rate and Timing of Nitrogen Applications on Forage Sorghum Biomass YieldForage Sorghum (Sorghum-Sudan grass) is a forage crop harvested in the form of silage or dry-hay and is intended to distribute to livestock as feed. The research objective for this study is to observe how nitrogen timing plays a role in crop total biomass yield. Observations and data were collected during the 2021 growing season, with a total of two harvests allowed due to weather conditions in the area. This trial was conducted at two locations: Lake Carl Blackwell near Stillwater, Oklahoma and... B. Arnall, S. Sawatzky, S. Akin, M. Thomas, R. Singh, W.R. Raun |
3. Does Late-season Nitrogen Impact Grain Protein Concentration in Wheat? A Global Meta-analysisSustainable improvements in wheat production entails increasing yield while maintaining or improving grain quality, which most of the time are negatively correlated. However, attemps to synchronize N supply with crop N demand through N timing can help to obtain both improved yield and quality by enhancing N use efficiency (NUE) and reducing N losses. Late season applied N is a challenging practice that when used correctly can generate posite NUE impacts. Additionally, a systematic assessment... R. Lollato, N. Giordano |
4. Effect of Nitrogen Rate and Timing on Forage Sorghum Biomass Yield and QualityForage Sorghum is a summer annual sorghum-sudan hybrid that is a high yielding and high-quality source of feed for livestock. Forage sorghum can produce multiple biomass harvests in a single growing season, and is harvested in a silage or dry hay form. Because of the high yield of forage sorghum, this crop is a valuable choice for producers in Oklahoma and surrounding regions with heavily dominated livestock production. For such a high yielding crop nitrogen fertilizer application is extremely... S. Sawatzky, S. Phillips |
