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.

This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Growing quality malting barley requires precise nitrogen (N) management due to strict grain quality requirements. The timing and the rate of N fertilizer application are essential management decisions, but their impacts vary with environmental conditions. In order to improve the quality and yield outcomes for California malting barley the following studies: 1. Quantified the effect of different N fertilizer rates and application times on malting barley yield and quality. 2. Quantified the independent and combined ability of a suite of in-season proximal sensing measurements to predict site-specific yield and quality outcomes for malting barley. We found that there was a highly inconsistent response of malting barley to N fertilizer application rates and timings. The amount and timing of ideal N fertilizer is highly site-year specific. Patterns in the soil, climate, and management change the crop response to N fertilizer but in general the total N fertilizer required to achieve maximum yield is equal to or greater than the amount to achieve acceptable protein. Site-specific normalization of boot (Feekes 10) spectral reflectance indices as well as grain outcomes made it possible for grain protein yield to be accurately represented as a function of proximal sensing data. Handheld NDVI was not improved by the addition of leaf chlorophyll measurements but was also not ideal due to saturation. Grain protein yield predictions were improved with other vegetation indices, such as OSAVI, calculated from UAV mounted multispectral cameras due to less saturation and soil interference. Improved malting barley management needs to be site-specific, which requires an understanding of the site’s yield potential and climate. Multispectral data from proximal sensing devices can add information about in-season variability and its probable effect on grain outcomes.

This book was released on 1970 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: Field experiments were conducted at the New Jersey Agriculture Experiment Station, Adelphia, New Jersey in 1968 and 1969. These studies involved: (a) three seeding rates of 81, 108 and 162 kg. per hectare each seeded in three inter-row spacings of 15.3, 22.9 and 30.5 cm. and (b) four levels of nitrogen, 28, 56, 84 and 112 kg. per hectare, applied as split application in fall and spring. The object of the experiments was to study the influence of three cultural treatments on grain yield, yield components, grain protein and other seed and plant characteristics of a newly introduced, two-row barley cultivar, Tschermak. The first experiment was laid out in factorial and the second in a 4 x 4 balanced lattice design. The grain yield was signicantly influenced by both the seeding rates and spacings in 1969. Although the grain yield was not significantly affected by these treatments in 1968, the tratments had a significant effect on individual yield components. All the three yield components, number of spikes per unit area, seed weight and number of kernels per spike, were significantly influenced by spacing in both the seasons. An increase in inter-row spacings decreased the number of spikes per unit area as a result of greater intra-row competition caused by a higher stand density within a row. This was because at the wider inter-row spacings the number of rows per unit area was reduced. The highest seed weight resulted from the 108 kg. Seeding rate in 1969, and the same seeding rate produced significantly heavier seeds than 162 kg. seeding rate in 1968. The widest inter-row spacing of 30.5 cm produced significantly heavier seeds than the other two inter-row spacings in both seasons. The plant height was not significantly influenced by seeding rates in either experiment but the differences due to inter-row spacings were highly significant in both years. The multiple correlation coefficient showed that number of kernels per spike and seed weight contributed 62 percent of the grain yeld in 1969. The grain yield was significantly influenced by rate and time of nitrogen application in both seasons. In general, the yield increased with increasing rates of nitrogen. Among the yield components, the number of spikes per unit area was significantly affected in both seasons. The higher rates of nitrogen produced more spikes per unit area. The spring application produced the highest number of spikes per unit area from single applications. Seed weight was not significantly affected in either year. The differences in the number of seeds per spike were also not significantly affected in either year. The percentage of plump kernels decreased with increasing rates of nitrogen in 1968. The grain protein was significantly influenced by the treatments in both seasons. Plant height was also significantly influenced by nitrogen treatments. The higher rates produced taller plants and the late spring application produced shorter plants than the other times of application in both seasons. Lodging occurred in the 1968 season. The higher rates of nitrogen lodged the crop more severely. Multiple correlation of coefficients showed that number of seeds and number of kernels per spike contributed 88.9 and 65.5 percent of the grain yield in 1968 and 1969, respectively.

Available in PDF, EPUB and Kindle. Book excerpt: Presenting the first continental-scale assessment of reactive nitrogen in the environment, this book sets the related environmental problems in context by providing a multidisciplinary introduction to the nitrogen cycle processes. Issues of upscaling from farm plot and city to national and continental scales are addressed in detail with emphasis on opportunities for better management at local to global levels. The five key societal threats posed by reactive nitrogen are assessed, providing a framework for joined-up management of the nitrogen cycle in Europe, including the first cost-benefit analysis for different reactive nitrogen forms and future scenarios. Incorporating comprehensive maps, a handy technical synopsis and a summary for policy makers, this landmark volume is an essential reference for academic researchers across a wide range of disciplines, as well as stakeholders and policy makers. It is also a valuable tool in communicating the key environmental issues and future challenges to the wider public.
