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.

This book was released on 2010-07-05 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetics and Improvement of Barley Malt Quality presents up-to-date developments in barley production and breeding. The book is divided into nine chapters, including barley production and consumption, germplasm and utilization, chemical composition, protein and protein components, carbohydrates and sugars, starch degrading enzymes, endosperm cell walls and malting quality, genomics and malting quality improvement, and marker-assisted selection for malting quality. The information will be especially useful to barley breeders, malsters, brewers, biochemists, barley quality specialists, molecular geneticists, and biotechnologists. This book may also serve as reference text for post-graduate students and barley researchers. The authors for each chapter are the experts and frontier researchers in the specific areas. Professor Guoping Zhang is a barley breeder and crop physiologist in Department of Agronomy, Zhejiang University of China. Dr. Chengdao Li is a senior molecular geneticist and barley breeder in Department of Agriculture & Food, Western Australia. He is also an adjunct professor in Murdoch University of Australia and Zhejiang University of China.
