Nitrogen is the most important macronutrient needed for plant growth and development. The availability of nitrogen in the soil fluctuates greatly in both time and space. Crop plants, except leguminous plants, depend on supply of nitrogen as fertilizers. Large quantities of nitrogen fertilizers are applied to crop plants, but only 33% of it is utilized by the by: 6.

    Nitrogen use and behavior in crop production. Urbana, Ill.: Agricultural Experiment Station, College of Agriculture, University of Illinois at Urbana-Champaign, (OCoLC) Material Type: Government publication, State or province government publication: Document Type: Book: All Authors / Contributors: L Fred Welch. This research aimed to compare the productivity of three species of pulse plants (Vicia faba L., Pisum sativum L., Lupinus angustifolium L.) in acidic sandy loam soil and to determine the influence of NPK (N0P0K0, N0P27K73, N30P27K73) fertilisers on grain yield and nitrogen experiments were conducted Voke Branch of Lithuanian Research Centre for Agriculture and Forestry Author: Liudmila Tripolskaja, Rita Asakaviciute.

      The assimilation of inorganic nitrogen into organic form has marked effects on plant productivity, biomass, and crop yield (Hageman and Lambert, ; Lawlor et al., ). As such, a tremendous amount of biochemical and physiological studies have been performed on nitrogen assimilatory enzymes from a variety of plant species, especially crops and by: Nitrogen (N) fertilizers are needed to enhance maize (Zea mays L.) production. Maize plays a major role in the livestock industry, biofuels, and human nutrition. Globally, less than one-half of applied N is recovered by maize. Although the application of N fertilizer can improve maize yield, excess N application due to low knowledge of the mechanisms of nitrogen use efficiency (NUE) poses Cited by: 1.

This GS/GOGAT pathway of ammonia assimilation is of crucial importance for crop growth and productivity and ultimately animal and human nutrition.

Glutamate dehydrogenase (GDH) is now considered to be only involved in glutamate catabolism to form ammonia, an Cited by: The realization of this book stems from a national symposium, Nitrogen in Crop Production, held in Sheffield, Alabama, 25–27 Mayjointly sponsored by the Tennessee Valley Authority National Fertilizer Development Center, the American Society of Agronomy, the Crop Science Society of America, and the Soil Science Society of America.

In addition, global nitrogen cycling and its availability from soil, and a case study of field estimation of nitrogen balance at a university farm are described. Part II is entitled Nitrogen Absorption in Plants. The absorption and assimilation of ammonia and nitrate First published: 06 Jun, Crop rotation, soil reclamation, forestry, forage mixed cropping, intercropping with grasses and legumes, associative nitrogen fixation with non-legume crops, such as sugarcane, and other agricultural practices in Brazil are also dependent on biological nitrogen fixation.

Review: Nitrogen assimilation in crop plants and its affecting factors. Can. Plant Sci. – In this review we discuss mainly nitrogen assimilation in crop plants and factors affecting the related process.

Nitrogen is a major macro-element limiting Cited by: Nitrogen Assimilation and its Relevance to Crop Improvement of Nitrogen assimilation and crop productivity book and hence reduces their total plant nitrogen (N) assimilation and ultimately growth.

gains in global crop production. crop varieties with high nitrogen use efficiency (NUE) is imperative for sustainable agriculture. The nitrogen use efficiency (NUE) for crop plants is of great concern globally. The rapid increasing world population needs crop genotypes that respond to higher nitrogen and show a direct relationship to yield with use of nitrogen inputs, i.e.

Nitrogen Fixation in Crop Production will serve as an outstanding resource for research scientists and graduate students, and for individuals developing public policy for research programs to improve crop production throughout the world.

Marcus M. Alley, President of the American Society of Agronomy. Of course, if the rate of supply from storage plus soil drops below the requirement in the long-term then growth will be restricted. Here, an understanding of the basic processes of carbon and nitrogen assimilation and how they relate to crop yield is of importance.

It could guide agronomic practice, breeding and genetic engineering. N-response curvesCited by: Nitrogen is a primary driver of crop production. Given sample sunlight and water and favorable temperatures, yields of dry substance and grain are loosely linked to the availability and uptake of Author: Natasa Cerekovic.

Nitrogen (N) is one of the most important nutrients required for crop production. Application of fertilizer N results in increased growth and higher biomass yields.

Abstract. An understanding of the relationship between N assimilation and grain yield and protein, and the measurement of genetic variation in preanthesis and postanthesis N assimilation in wheat (Triticum aestivum L.) are necessary to achieve additional gains in selecting for both high grain yield and high graintotal N assimilation in the spring wheat cultivars ‘Anza’ and.

Nitrogen is the most yield-restraining nutrient in crop production globally. Efficient nitrogen management is one of the most important factor for improving nitrogen use efficiency, field crops productivity and profitability.

This book covers all aspects of the transfer of nitrogen from the soil and air to a final resting place in the seed protein of a crop plant. It describes the physiological and molecular mechanisms of ammonium and nitrate transport and assimilation, including symbiotic nitrogen fixation by the Rhizobiacea.

Effects of N in crops are profound, but much understanding of crop growth responses to N is empirical. This review attempts to develop a mechanistic understanding of the effects of N on crop biomass accumulation by elucidating quantitative relationships among leaf N content, CO 2 assimilation rate, and crop radiation use efficiency.
