1. Plant Population Influences on Maize Physiological Responses to Nitrogen ApplicationPast genetic improvements in maize ( Zea mays L.) have led to the creation of modern hybrids that are increasingly tolerant to a variety of stresses and, in particular, to high plant populations. However, high plant densities can adversely a ffect overall grain yield due to greater intra- specific (within species) competition for lim iting resources. This competition increases barrenness and plant-to-plant variability for grain yield (GY CV) and other morpho-physiological traits. In this study, we... |
2. Nitrogen Use Efficiency and Corn Yield as Affected by Applied Sulfur and Nitrogen FertilizerOverall corn (Zea mays L.) yield response, as well as nitrogen uptake and nitrogen use efficiency, can be affected by multiple factors, including the supply of other nutrients such as sulfur. The objective of this study was to evaluate the effect of nitrogen with added sulfur fertilizer on corn response parameters i) whole plant nitrogen uptake, ii) yield, and iii) nitrogen use efficiency when compared to nitrogen alone. Nitrogen Use Efficiencies evaluated in this study included i) Apparent... T. Husa, D. Ruiz diaz |
3. Corporate Sustainability Initiatives and Their Interface with Crop Nutrient ManagementAn increasing number of corporations are establishing sustainability initiatives. For ag/food companies, these interface with nutrient management mainly via nitrogen—a lot of carbon dioxide is produced during nitrogen fertilizer manufacture, and some nitrogen fertilizer is converted to nitrous oxide (a potent greenhouse gas) after application. A corporate sustainability representative, a nitrous oxide expert, and a farmer will present their views and then take questions... P. Carter, R. Sirolli, G. Robertson, M. Hora |
