Malting Barley Grain Quality and Yield Response to Nitrogen Fertilization in the Arsi Highlands of Ethiopia
Author(s): Kedir Jemal* and Ahmed Geleto
The malting industry in Ethiopia is often challenged by the availability of barley that meets the quality and quantity
requirements set by the industry. Field experiments were conducted to evaluate the effects of mineral nitrogen
fertilizer rates on actual yield and quality response of malt barley varieties and to determine economic optimum rates
of nitrogen fertilizer for the productivity of the crop arranged in randomized complete block design in factorial
arrangement with three replications. The treatments are three malt barley varieties, namely traveler, ibon and local
and four levels of N (0 kg N/ha, 50 kg N/ha, 100 kg N/ha and 150 kg N/ha. The study revealed that nitrogen
fertilization with 150 kg ha-1 nitrogen fertilizer rate improved barley yield and quality than the rest nitrogen fertilizer
rates. The different barley varieties and nitrogen fer.. View more»
