Improving Nitrogen Use Efficiency for Cereal Production
found, had they considered N derived from the soil (Keeney, 1982; van der Ploeg et al., 1997). Using the Worldwide, nitrogen use efficiency (NUE) for cereal production same references and assumptions in Table 1, cereal (wheat, Triticum aestivum L.; corn, Zea mays L.; rice, Oryza sativa L. and O. glaberrima Steud.; barley, Hordeum vulgare L.; sorghum, NUEs are 42 and 29% in developed and develop...
متن کاملImproving Nitrogen Use Efficiency in Crops for Sustainable Agriculture
In this review, we present the recent developments and future prospects of improving nitrogen use efficiency (NUE) in crops using various complementary approaches. These include conventional breeding and molecular genetics, in addition to alternative farming techniques based on no-till continuous cover cropping cultures and/or organic nitrogen (N) nutrition. Whatever the mode of N fertilization...
متن کاملImproving nitrogen use efficiency of dairy cows in relation to urea in milk – a review
Dietary protein intake is the most important factor determining milk production, milk composition, milk nitrogen efficiency, urinary nitrogen losses, urea content in milk and consequently, ammonia emissions from dairy cow manure. According to the nutrition requirements two main protein sources are available for cows: rumen degradable protein, provided to the animal through ruminally synthesized...
متن کاملStrategies for Improving Potassium Use Efficiency in Plants
Potassium is a macronutrient that is crucial for healthy plant growth. Potassium availability, however, is often limited in agricultural fields and thus crop yields and quality are reduced. Therefore, improving the efficiency of potassium uptake and transport, as well as its utilization, in plants is important for agricultural sustainability. This review summarizes the current knowledge on the ...
متن کاملBiotechnology 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...
