Influence of Organic Fertilizers on Productivity of Barley: A Review
2022
Yimer, Arebu Hussen
Barley (Hordeum vulgare L.) is one of the ancient cereal crops of agriculture in the world and one of the first domesticated cereals and fourth largest cereal crop next to maize, wheat and rice in the world. It contributes seven percent of the total cereal production. The production of barley in Ethiopia reduced by many factors from these biotic factors including rodents, pathogens, diseases, weed, pests, insects and abiotic stress like drought, flooding, temperature stress, salinity, poor management practice, frost, poor soil fertility, agronomic practice etc. among those the most important factors that reduce yield of barley in Ethiopia are the use of inappropriate organic fertilizers. Thus, the main objective of this paper is to review the influence of organic fertilizers on productivity of barely. The review was done by collecting the various published and unpublished materials relevant information from different literature sources like libraries, research report, journals, books and Internet center. As various scholars mentioned organic fertilizers affect the growth, development and yield of barley. The uses of farm yard manure, animal manure, poultry manure and vermi compost considerably improved yield and yield component of barley such as number of tillers per plant, spike length, straw, biomass, grain weight and grain yield. It concludes using organic fertilizer has crucial role for increasing barley production and productivity.
