Nitrogen is an important macronutrient required for plant growth, and is a limiting factor for crop productivity. Improving the nitrogen use efficiency (NUE) is therefore crucial. At present, the NUE mechanism is unclear and information on the genes associated with NUE in soybeans is lacking. cystathionine beta synthase (CBS) domain-containing proteins (CDCPs) may be implicated in abiotic stres...

In order to investigate the effect of urea and Azocompost on economic yield, nitrogen use efficiency (NUE) and radiation use efficiency (RUE) of wild majoram, a factorial experiment was conducted based on randomized complete block design with three replications at Yazd and Mashhad, Iran, during 2012-2013 growing season. Four urea levels and four Azocompost levels (to provide 0, 40, 80 and 120 k...

Nitrate plays a major role in the yield and quality of tobacco plants. This work explored the nitrogen-use efficiency (NUE) and how it can be affected by grafting. Two experiments were designed: in the first, using six commercial tobacco cultivars, the best cultivar for the NUE was selected and analysed for foliar NO3− content, total N, nicotine and nitrate reductase (NR) activity. The results ...

The temperature responses of photosynthesis (A) and growth were examined in rice and wheat grown hydroponically under day/night temperature regimes of 13/10, 19/16, 25/19, 30/24 and 37/31 degrees C. Irrespective of growth temperature, the maximal rates of A were found to be at 30-35 degrees C in rice and at 25-30 degrees C in wheat. Below 25 degrees C the rates were higher in wheat, while above...

To satisfy future demands, the increase of wheat (Triticum aestivum L.) yield is inevitable. Simultaneously, maintaining high crop productivity and efficient use of nutrients, especially nitrogen use efficiency (NUE), are essential for sustainable agriculture. NUE and its components are inherently complex and highly influenced by environmental factors, nitrogen management practices and genotypi...

Nutrient use efficiency (NUE) is a critically important concept in the evaluation of crop production systems. It can be greatly impacted by fertilizer management as well as by soiland plant-water management. The objective of nutrient use is to increase the overall performance of cropping systems by providing economically optimum nourishment to the crop while minimizing nutrient losses from the ...

Children and adolescents engage in activities similar to demands known to cause musculoskeletal disorders in working adults. In this study, computer and electronic game use were proposed as contributors to neck or upper extremity (NUE) symptoms of pain or discomfort in adolescents. A cross-sectional survey was distributed in a northeastern US city. Subjects reported use of computers at school a...
