Modification of irrigation scheduling and management improvement of irrigation systems are two essential factors that have significant impact on agricultural water use efficiency. Therefore, a field experiment was conducted to evaluate the effect of tape drip irrigation (T) and furrow irrigation systems (S) under different irrigation regimes on yield and yield components of soybean in growing s...

An experiment was performed at the Miyandoab Agricultural Research Station to study yield and water use efficiency of furrow and tape irrigation systems in one-row and two-row planting patterns, and to investigate density of grain corn SC704. The experimental design was a completely randomized block arranged in Strip Split Plots with three replications in 2010. Irrigation treatments were applie...

BACKGROUND: Deficit irrigation strategies were effective in saving volume of water. Potassium is an essential nutrient that affects most of the biochemical and physiological processes are involved in plant resistance to biotic and a biotic stresses. OBJECTIVES: This study was conducted to assess effect of different pattern of irrigation and several source...

Partial root-zone drying or partial root-zone irrigation is a newly proposed water saving technique which may improve water use efficiency and nutrient uptake by a crop without affecting its yield. A study was conducted to investigate the response of furrow-irrigated okra to partial root zone drying in relation to cropevapotranspiration (ETc), vegetative growth, yield, and nutrient use effi...

The interactive influence of furrow surface seal formation and surge irrigation (intermittent flow) on furrow infiltration into a Portneuf silt loam soil was measured with a recirculating infiltrometer. When the formation of a surface seal was prevented by a layer of cheesecloth laid on the furrow perimeter, flow interruption increased furrow bed bulk density by 100 kg/m 3 and decreased infiltr...

Considering water scarcity in Iran, application of deficit irrigation or water stress on some crops is inevitable. We need to provide appropriate design for deficit irrigation. Furrow irrigation management to obtain high efficiency and uniformity is difficult. Therefore, to investigate the variation of the input discharge, the cut-off time and furrow length that are effective on the efficiency ...

Iran with a cultivation area of 45000 ha and production of 150 ton/year is the number one saffron producer in the world. Planting of large size corms will increase flowering, but production of corms (number and size) may be affected by irrigation method or frequency. In this research which is performed in the farm of College of Agriculture, Shiraz University, the effects of method and frequency...

In this study, the effect of deficit irrigation with every–other furrow irrigation method, which is an innovated method in farm irrigation management, was examined on sorghum (Sorghum durra L.) in Bajgah and Kooshkak areas of Fars Province. The experimental design was split plot with three main plots of irrigation interval (10, 15 and 20 days), three subplots of irrigation methods (ordinary fur...

Infiltration phenomenon, has a direct impact on rainwater harvesting in fields under irrigation. In order to solve this problem (reduced infiltration and increased runoff), a few strategies can be suggested. Taking long-term decision for increasing the efficiency of irrigation should be strongly suggested. At the same time, ways in which customized irrigation is optimized must be studied. An ol...
