Nitrogen use efficiency revisited

Oecologia, 2011
Nitrogen use efficiency (NUE) was originally defined as the dry mass productivity per unit N taken up from soil. The term was subsequently redefined as the product of nitrogen productivity (NP) and mean residence time of nitrogen (MRT). However, this redefinition was found to contradict the original definition under certain conditions, and confusion ...

Nitrogen Use Efficiency in Plants

2011
Nitrogen fertilizers are necessary to enhance agricultural production and to sustain food security. However, their inefficient use accrues from inherent limitations of the crop plants as well as the manner in which N fertilizers are formulated, applied and managed. The main aim of the book is to assess the various aspects of the fate of fertilizer N in

Physiological adaptations for nitrogen use efficiency in sorghum

Plant and Soil, 2002
Known high nitrogen utilization efficiency (NUE1, biomass per unit plant N) China lines of sorghum, China 17 and San Chi San, were compared with relatively low NUE1 U.S. lines, CK60 and Tx623, for both their physiological and biochemical adaptations to tolerate an imposed N stress in the greenhouse.

Photosynthesis and Nitrogen-Use Efficiency

2006
In C3 crop plants about 60–80% of leaf nitrogen (N) is invested in the photosynthetic apparatus, and N nutrition plays a crucial role in determining photosynthetic capacity. The proportion of leaf N invested in photosynthetic components is fairly constant.

The Genetics of Nitrogen Use Efficiency in Crop Plants

Annual Review of Genetics, 2015
In the past 50 years, the application of synthetic nitrogen (N) fertilizer to farmland resulted in a dramatic increase in crop yields but with considerable negative impacts on the environment. New solutions are therefore needed to simultaneously increase yields while maintaining, or preferably decreasing, applied N to maximize the nitrogen use ...

Growth and nitrogen metabolism are associated with nitrogen-use efficiency in cotton genotypes

Plant Physiology and Biochemistry, 2020
Crops, including cotton, are sensitive to nitrogen (N) and excessive use can lead to an increase in production costs and environmental problems. We hypothesized that the use of cotton genotypes with substantial root systems and high genetic potentials for nitrogen-use efficiency (NUE) would best address these problems.

Breeding for Nitrogen Use Efficiency

2012
Nitrogen (N) is a constituent of several organic compounds in plants. Consequently, this element is the most essential to plants. The identification of genotypes able to use nitrogen more efficiently is a slow process due the complexity of the metabolism of nitrogen, the influence of several environmental factors‚ and the great variation in the species

Nitrogen preference and genetic variation of cotton genotypes for nitrogen use efficiency

Journal of the Science of Food and Agriculture, 2020
AbstractBACKGROUNDAlthough nitrogen (N) availability is a major determinant of cotton production, little is known about the importance of plants' preference for ammonium versus nitrate for better growth and nitrogen use efficiency (NUE). We aimed to assess the growth, physiology, and NUE of contrasting N‐efficient cotton genotypes (Z‐1017, N‐efficient ...

Response of nitrogen use efficient sorghums to nitrogen fertilizer

Journal of Plant Nutrition, 1998
Abstract Little information is available on the response of grain sorghum [Sorghum bicolor (L.) Moench] genotypes differing in nitrogen (N) use efficiency (NUE) (g DM g N‐1) to added N fertilizer. Such knowledge is important for reducing the reliance upon fertilizer N. A dryland field experiment was conducted in 1993 and 1994 at Mead, NE evaluating the
