Subsurface soil water retention technology is a modern tool to increase the yield and improved saving. The goal of this paper review gathered three selected local experimental woks carried out in different regimes Iraq purposes improving productivity for strategy plants some vegetables crops irrigated by utilizing irrigation systems installing membrane trough. Moreover, retained rainfall was al...

To determine root growth and grain yield of winter wheat (Triticum aestivum L) under moderate drought stress, a nursery experiment and a field trial were conducted with or without water stress using three representative cultivars released in different years: CW134 (old landrace), CH58 (modern cultivar) and CH1 (new release). In the nursery experiment, plants were grown in soil-filled rhizoboxes...

Cropcheck developed following the identification of limitations to the Transfer of Technology (TOT) extension model which occurred through the 1970’s and into the early 1980’s (Lacy 2011). Irrigated wheat yields stagnated with high variability from year to year and no understanding as to why this occurred. This was despite several communication methods (farm visits, demonstrations, plot trials,...

In this paper we present a methodology within the multi-criteria paradigm to assist policy decision-making on water management for irrigation. In order to predict farmers’ response to policy changes a separate multi-attribute utility function for each homogeneous group, attained applying cluster analysis, is elicited. The results of several empirical applications of this methodology suggest an ...

Several technologies have been provided to farmers increase production under the rainfed systems of Ethiopia. However, much attention has focused on drought emergency relief and associated interventions. Conservation agriculture (CA), among others, recently encouraged as part sustainable intensification technology in Ethiopian smallholder farming systems. CA research Ethiopia traditionally stay...
