Genomic improvement of nitrogen utilization efficiency in maize
… application rates to boost yields. Consequently, nitrogen (N) use in the United States has increased nearly six fold in the last fifty years to more than 13 million tons applied in 2014, an increase that mirrors worldwide trends. The production of N fertilizer is dependent on energy inputs to …

Fine mapping and characterization of genes involved in maize nitrogen utilization efficiency
… comes from maize’s responsiveness to nitrogen fertilizers. Despite their importance in crop production, these fertilizers can place an economic burden on growers and can also have negative environmental and health impacts when applied in excess. In order to mitigate the negative …

Nitrogen utilization in creeping bentgrass
Efficient approaches for screening nitrogen utilization efficiency (NUE) of turfgrasses are needed, since nitrate contamination of ground water is a concern on golf courses. In the first study, the conditions of N utilization of fourteen bentgrass cultivars were compared in hydroponic solution …

Genetic Analysis of Nitrogen Remobilization and Kernel Compositon in Zea Mays L. and Sorghum Bicolor (L.) Moench
<p>Genetic Analysis of Nitrogen Remobilization and Kernel Composition in Zea Mays L. and Sorghum Bicolor (L.) Moench. Major Professor: Mitchell Tuinstra. Modern maize (Zea mays L.) production relies heavily on nitrogen fertilization for high productivity. Over-application of nitrogen fertilizers in …

Genetic improvement for nitrogen utilization in maize
Increased nitrogen use efficiency (NUE) is an important target for future maize improvement. Essential to the design of an effective breeding program to select maize hybrids with enhanced NUE is an understanding of past progress, variation among maize germplasm for NUE and its component traits, and …

Nitrogen partitioning, content and efficiency in hybrid canola
… produced in Saskatchewan every year. Farmers use nitrogen fertilizer supply so that canola crops reach their yield potential. Canola, like corn, is a crop that is know for high nitrogen fertilization requirements. A two year study was conducted at three locations across Saskatchewan with the main …

Use of Newly Developed Blended Feed Supplement on Rumen Parameters and Milk Fat in Dairy Cows
… and its impact on milk production and nitrogen utilization, with the aim of finding an alternative inexpensive supplement source for dairy cows instead of bypass fats and proteins. BFS was compared with conventional protein (canola meal) and energy (barley grain) feeds. Three samples of …

Discovery and characterization of genes controlling nitrogen utilization in maize
… has a well-documented response to supplemental nitrogen (N). As a result of this response, supplemental N is applied to nearly all maize grown in the U.S. and other industrialized nations, and the use of N fertilizer in developing countries is on the rise. While sufficient nitrogen fertilization …
