Abstract

In this study, the effect of furrow Firming rollers were investigated to improve furrow irrigation parameters such as: advance time, runoff, deep percolation and irrigation efficiency (application efficiency) in the roller treatments, nonroller treatments (traditional) and treatment of including compacted with tractor wheel in the Miandab agriculctural station in west Azerbaijan during 2001-2002. After the land praparing, rollers were designed and built at 6 different size including with three diameter: 25, 40 and 55 cm and two width: 12.5 and 15 cm. Evauation was conducted with three sinkers that weights includes: 25, 50 and 75 kg were loaded on the rollers. Among between different roller dimentions, the highest irrigation efficiencies were 55.4 and 55.3% which obtained with the roller dimentions of 55 and 15 cm diameter and width, respectively, and among the weight treatments the highest level of irrigation efficiency was related to weight treatment equal 75 kg and about 55.18%. while the irrigation efficiencies were 48.9 and 45.4% in compacted furrow with tractor wheel and non compacted, respectively. Results showed that the effect of width and diameter of roller and sinkers were significant on the irrigation parameters and increasing of irrigation performance.
