The variability of fresh water availability in arid and semi-arid countries poses a serious challenge to farmers to cope with when depending on irrigation for crop growing. This has shifted the focus onto improving irrigation management and water productivity (WP) through controlled deficit...

In water stressed regions such as the Central Rift Valley of Ethiopia, increasing Crop Water Productivity (CWP) is imperative for sustainable food and water security. This paper presents CWP of Teff (Eragrostic Tef), a staple food in Ethiopia and an important export crop. Field experiments were...

Optimal crop water allocation has become more challenging in drier areas of the world (short of rainfall) due to increased water scarcity and more frequent droughts. alternative cropping patterns, reallocation of water resources and modification of irrigation are some of the strategies used to...

A number of column experiments were conducted in order to determine groundwater contributions by safflower (Carthamus tinctorius L.) under different saline shallow groundwater (Gw), surface water (Sw) and deficit irrigation schemes. The plants were grown in 16 columns with 0.40m diameter and...

Yield response factors of a given crop can be determined following the FAO approach (Doorenbos and Kassam, 1979. Yield response to water. FAO Irrigation and Drainage Paper no. 33. Rome, Italy, pp. 1–40) either by applying deficit irrigation throughout the whole growing period, or at one stage...

Knowing the performance of short season crops under deficit irrigation has a paramount importance for arid and semi-arid regions with limited access to on-farm water harvesting or other irrigation infrastructure. In this research, the performance of mungbean, a newly introduced crop into the...

An experiment was carried out in a high-density olive (Olea europaea L. cv. Frantoio) orchard to determine the effect of different irrigation regimes (full, deficit, complementary) on virgin olive oil (VOO) quality over three consecutive years. Irrigation had negligible effects on free acidity,...

Root pruning is an effective approach for controlling vegetative growth of pear trees (Pyrus communis L.), yet the underlying mechanisms for such effect remain largely elusive. A two-year field experiment was conducted to investigate the effect of root pruning and irrigation regimes on leaf...

This study aims to assess the economic feasibility of full and deficit irrigated maize using center pivot, set sprinkler systems and drip tape systems through multicriteria analysis. Different irrigation treatments were evaluated and compared in terms of beneficial water use and physical and...
