Biotechnology Approaches to Improving Maize Nitrogen Use Efficiency
Nitrogen (N) is an essential and often limiting nutrient to plant growth. Maize grain yields are highly responsive to supplemental N, leading to annual application of an estimated 10 million metric tons of N fertilizer to the maize crop worldwide (FAO 2004). Nearly all cultivated maize in developed countries receives some form of N fertilizer and N use is increasing in developing countries, whe...
متن کاملGenetic Engineering Approaches to Improving Nitrogen Use Efficiency
Since nitrogen (N) is the most essential nutrient for plants and a major limiting factor in plant productivity, doubling agricultural food production worldwide over the past four decades is associated with a 20-fold increase in N fertilizer use. As a consequence, use of N fertilizers in agriculture has already shown a number of detrimental environmental impacts. Therefore, the need to reduce N ...
متن کاملAgroecosystems, nitrogen-use efficiency, and nitrogen management.
The global challenge of meeting increased food demand and protecting environmental quality will be won or lost in cropping systems that produce maize, rice, and wheat. Achieving synchrony between N supply and crop demand without excess or deficiency is the key to optimizing trade-offs amongst yield, profit, and environmental protection in both large-scale systems in developed countries and smal...
متن کاملEfficiency of nitrogen fertilization in spring wheat
An assessment of the nitrogen fertilization efficiency should not only include quantitativeand qualitative yield changes, but also an analysis of formation some indicators such as: Nharvest index (NHI), N use efficiency (NUE), N utilization efficiency (NUtE), N agronomicefficiency (NAE), N physiological efficiency (NPE) and N apparent recovery fraction (NRF).The objective of the study was the e...
متن کاملAutomated Reticle Handling: a Comparison of Distributed and Centralized Reticle Storage and Transport
The implementation of Automated Material Handling Systems (AMHS) in 300mm semiconductor facilities provides the opportunity to realize significant benefits in fabricator productivity and performance. The leverage associated with automated reticle delivery to photolithography process tools may be less apparent than a fab-wide AMHS. However, a high product mix environment requires the tracking, s...
