Abstract:
Nitrogen plays a key role in cereal production because its requirement is highest among all the essential plant nutrients, therefore, care must be taken when the crop is taken for malt production. Grain yield and protein content are the characteristics strongly related to available nitrogen. It has been observed that higher nitrogen rates can result in translocation of excessive amount of nitrogen from vegetative organs to grains, thereby resulting in higher protein content and poor malt quality. Similarly lower rates of nitrogen application may result in reduced grain yield and quality below the acceptable levels. A proper supply of nitrogen to plants helps them to accumulate protein in their seeds and to increase their weight. Several researchers and eminent investigators observed that nitrogen dose varies with variety, soil type and location of the experiment. The review indicated that increasing levels of nitrogen application affected nearly all aspects of malt processing and malt quality. Grain protein levels increased with increasing nitrogen rates but malt extract levels decreased with increasing nitrogen levels. Therefore, appropriate nitrogen fertilization rates need to be applied for malt barley to achieve a balance between optimum grain yield and protein concentration.
