This book was released on 2012-02 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: Production of barley is affected by many factors: sowing, topography, fertilization, temperature flux etc. Among them temperature plays an important role in plant growth and development. Due to high temperature, vegetative phase shortened and steep rise in temperature at the grain filling stage which causes abortion of florets and reduced kernel weight. Most of the characters were highest in early sown (S1 and S2) and higher nitrogen (N4). Grain filling duration from anthesis to physiological maturity was shortened by 1.37 and 1.77 day / C rise in temperature, grain weight decreased by 0.18 and 0.82 mg/ C rise in temperature and grain weight increased by 0.30 and 0.07 mg/day increase in grain filling duration in two consecutive years. Fertile tillers/plant, panicle length, number of spikelet/spike, 1000-grain weight and grain protein contents were proved to be the most stable yield components. Nitrogen utilization was also higher in early sowing and higher nitrogen concentration. NUE increased significantly up to N2 but NHI increased significantly up to N1. Experimental findings will help the barley growers and researchers to intensify their knowledge of proper crop management.

This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen (N) is one of the most important nutrients for plant growth and crop performance. Increases in the use of N have contributed to increases in agricultural production over the past 50 years. Large amounts of this fertilizer are applied to cereals crops to maximize yields; however, excessive fertilizer application is a source of several environmental problems, including pollution and increase in CO2 emissions. One way of minimizing N application to crops is by designing genotypes with increased nitrogen use efficiency (NUE). Previous studies showed that overexpression of alanine aminotransferase (AlaAT) resulted in significant increases in the NUE of canola and rice plants. This technology has been applied to barley, with preliminary studies showing promising results in terms of biomass increase and seed production. With the aim of having a more detailed understanding of the physiological mechanisms underpinning the performance of the AlaAT barley genotypes, an ecologically-focused approach was adopted to evaluate the efficiency of N use and growth performance in early vegetative stages of barley. To establish guidelines to study AlaAT overexpressing barley genotypes, a detailed growth analysis was first performed with wild-type plants grown on six N concentrations, to understand how N supply affects the carbon (C) and N economy of this crop at different stages of vegetative development. The results of these studies revealed interesting insights on the effect of N on the underlying growth parameters, and determined that the major factors affecting grown as a result of N availability are C and N allocation among above and below-ground organs. Furthermore, these studies revealed the importance of controlling for ontogenetic drift by comparing plants of similar masses when analyzing the effect of N availability on growth traits. Subsequently, analysis of the C and N economy of the AlaAT overexpressing barley genotypes revealed no increases in growth and N productivity compared to null controls. Biochemical measurements suggested that post-translational issues may have prevented increase in AlaAT activity and protein abundance during the vegetative period over which plants were grown. The role of N on agricultural production goes beyond the increase in plant growth and seed yield. N fertilization, in the form of NO3- also increases crop performance and survival during waterlogging. However, the mechanism behind this improvement in hypoxia tolerance has not yet been elucidated. With the aim of having a better understanding about N supply and hypoxia interaction, I analyzed the effect of NO3-availability on the global gene expression in response to hypoxia in barley. My results suggest that NO3- availability may be linked to the increase in ATP production, and that N supply affected numerous events within barley plants. This includes changes in N and C allocation that resulted changes in growth rate and biomass accumulation, protein expression, and transcriptomic responses to low oxygen stress. My thesis research suggests that increases in the efficiency of N use could be achieved by improving the capacity for N uptake and assimilation, associated with a reduction in the proportion of respiratory losses to maintain a large root system.

This book was released on 2012-07 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Barley (Hordeum vulgare L.) is one of the founder cereal crop, domesticated about 10.000 years ago in the Fertile Crescent from its wild relative Hordeum spontaneum. It is grown as commercial crop world-wide and produced for feed and malting. Malt is the second most important use of barley, which is used mostly in beer, but also in hard liquors, malted milk and flavorings in a variety of foods. One of the important management decisions for the malt barley producers is the amount of nitrogen fertilizer apply to the soil. High yield of good quality grain with appropriate protein content and kernel plumpness are the goal of barley growers. High amount of nitrogen fertilizer increases the protein contents in the grain as a result high protein content decreases the extract yield, results in turbid beer and slows down the start of germination, while a too low protein content results in a lower enzymatic activity and slow growth of yeast in brewery. So nitrogen fertilization strategies therefore, must be carefully tuned in order to balance some contradictory goals of maximum production with the need to achieve low N levels in grain.
