the current study was carried out with the aim of evaluating the effects of pressurized and furrow irrigation methods on the distribution of salinity and moisture in the soil profile. the experimental study design was a split plot layout with three irrigation method including furrow, surface drip (sd) and subsurface drip irrigation (ssd) using two water qualities, municipal effluent (0.509 ds/m...

Distributed irrigation systems are those in which the water access (via pump or human power), distribution (via furrow, watering can, sprinkler, drip lines, etc.), and use all occur at or near the same location. Distributed systems are typically privately owned and managed by individuals or groups, in contrast to centralized irrigation systems, which tend to be publicly operated and involve lar...

Soil and water resources can be severely degraded by salinity when total salt input exceeds output in irrigated agriculture. This study was conducted to examine partitioning of Ca2+, Na+, and Cl- between soil and soybean [Glycine max (L.) Merr.] plants under different irrigation regimes with both field and modeling assessments. In drip and sprinkler treatments, the irrigation water was salinize...

Background: For better water resources management in the areas of shortage for crop production, deficit irrigation is very important. The understanding yield response factor to crucial efficient management. Deficit studying factors always practiced way stressing demand crops. present study was done determination seasonal red Bombay onion variety under Arba Minch agro climate condition. Furtherm...

This paper examines the impacts of off-farm employment on irrigation water efficiency (IWE) with a set of household level data collected in Hebei Province in North China. A major finding is that households with higher shares of laborers working off-farm locally seem to achieve higher IWEs. The effect of local off-farm employment is greater among those households that have made more efforts to u...

soil infiltration characteristics affect the design, evaluation and management of furrow irrigation over afield. on the other hand, different variables influence furrow infiltration, making infiltration modeling for afield a complex process. this study was conducted to investigate the direct and indirect effects of allvariables affecting furrow infiltration. the blocked furrow method was used t...
