the effects of irrigation methods, various levels of water and nitrogen fertilizer on quality of cotton were studied at hashemabad cotton research station of gorgan in 2008. the experiment was conducted in split-split plot design with three replications. irrigation methods of furrow and sprinkler were main plots, various levels of water of 0%, 33%, 66%, 100% and 133% were subplots plots and var...
Advance velocity is an important factor in surface irrigation system design and simulation. Volume balance is a simple model based on continuity equation used in surface irrigation design and management. In the past volume balance models, it is generally assumed that the upstream depth of surface water is constant and equal to normal depth. This initial assumption may cause significant errors i...
In the present study, the effects of different levels of irrigation, organic mulch and planting method on the mungbean yield in Badjgah were investigated. The experimental plan in the first year was full randomized block, while in the second year, it was full randomized split-split plot block design, in three repetitions. The results showed that in the FI treatments, the yield was increased up ...

Skip furrow irrigation (SFI) can save water by irrigating every alternate furrow. Usually, irrigated furrows are alternated at each event under SFI. If fixed (permanent SFI, PSFI), more may be saved reducing the wetting area, and salts accumulate on dry side of ridge. Salt removal sheet, a method collecting sheet laid soil surface utilizing high evaporation demand in drylands, an efficient meas...
a field experiment was conducted in research farm of isfahan university of technology, isfahan, iran in 2011 . various weeding periods were investigated on growth and yield of potato under drip tape and furrow irrigation systems. a split plot arrangement was used in a randomized complete block design with three replications. irrigation treatments were included in main plots and periods of weed ...
