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...

Crop management strategies that improve Nitrogen Use Efficiency (NUE) increase profits while reducing the detrimental effects on the environment associated with fertilizer nitrogen (N) loss. Effective N management should include several critical factors that are very interrelated. A study was conducted at the Panhandle Research and Extension Center, Goodwell, OK to evaluate the effects of multi...

Cellular pH homeostasis is fundamental for life, and all cells adapt to maintain this balance. In plants, the chemical form of nitrogen supply, nitrate and ammonium, is one of the cellular pH dominators. We report that the rice nitrate transporter OsNRT2.3 is transcribed into two spliced isoforms with a natural variation in expression ratio. One splice form, OsNRT2.3b is located on the plasma m...

Nitrogen (N) is an essential and limiting nutrient for crop production, as it a structural part of plants involved in various processes. Worldwide, agricultural soils lack one or more nutrients, nitrogen them. Adding sufficient amount N will increase production. However, the overuse loss from soil-plant system detrimental to environment results economic losses. has reactive forms like ammonia, ...

ABSTRACT- Titanium is a beneficial element for plant since its promotive effect on plant metabolism has been well documented. However, the physiological role of this trace element in tomato is not clear. This experiment was conducted as a complete randomized design to study two concentrations of titanium (1 and 2 mg/L Ti) and 0 as control on physiological and nutrient properties of tomato cv. F...

Abstract Low nitrogen use efficiency (NUE) is ubiquitous in agricultural systems, with mounting global scale consequences for both atmospheric aspects of climate and downstream ecosystems. Since NUE-related soil characteristics such as water holding capacity organic matter are likely to vary at small scales (< 1 ha), understanding the influence on NUE subfield 32 ha) could increase fertilize...

Plantations are typically monocultures, which limits their sustainability. Therefore, understanding acclimatization strategies and resource use efficiencies in plant species life forms aids the improvement of vegetation diversity ecological functions. Here, 19 from forest plantations Fangshan, Beijing, China were studied. We determined net photosynthetic (Pn), transpiration rates (E), light res...
