Book Description
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.

Book Description
The rapid response of the agricultural sector to increased crop prices indicates that it is able to meet the world's overall food requirements. The problem lies more in the distribution of the agricultural output and the economic inability of a segment of the population to satisfy basic requirements. This document presents guidelines for governments on the development of fertiliser strategies. It illustrates the difference before and after the involvement of the private sector and offers solutions for improvement. The role of fertilisers in the development of agriculture is discussed with practical suggestions for decision-makers regarding production and import. The many issues involved in the efficient distribution and marketing of fertilisers are presented, together with an institutional framework for the integration of all the aspects into a comprehensive policy. There is a useful glossary.

Book Description
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.

Book Description
The Present agriculture scenario in Punjab is exerting tremendous pressure on it natural resource, especially over exploitation of under grounded water due to rice wheat rotation. In Rabi season, wheat is major cereal crop requiring 5 to 6 irrigations for optimum yield having lest industrial use which led to the problem of plenty. The present book is an effort to promote cultivation of low water requiring crop having high industrial use. Barley has the potential to develop better link between traditional agriculture to the world famous malting industry. Therefore, it is required to quantify the qualitative traits of barley as per the industrial standards growing in this region.

Book Description
Barley is one of the world's most important crops with uses ranging from food and feed production, malting and brewing to its use as a model organism in molecular research. The demand and uses of barley continue to grow and there is a need for an up-to-date comprehensive reference that looks at all aspects of the barley crop from taxonomy and morphology through to end use. Barley will fill this increasing void. Barley will stand as a must have reference for anyone researching, growing, or utilizing this important crop.
