Pakistan’s Irrigation system is more than a century old, the distribution system within any canal command is designed to distribute the canal water equitably ignoring rainfall patterns and underlying groundwater resources. Now, the groundwater contribution in meeting crop water requirement has even crossed the canal water supply in the existing scenario of increased cropping intensities. The un...

Cropping systems in Western Australia (WA) are strongly dominated by cereals (wheat, barley and oaten hay) and are inextricably linked to soil quality and moisture supply. So a major research challenge is to devise cropping systems that improve soil health and maximise water-use efficiency. For a profitable and sustainable production system there is a clear need for ‘break crop’ to provide a pe...

In a runoff irrigation system using levelled basins, the water uptake patterns of different plant species (Acacia saligna (Labill.) H. L. Wend. and Sorghum bicolor (L.) Moench.) with contrasting root and shoot development were compared. Rainfall amounts during 1995 led to enough runoff water for realizing two cropping cycles. The amount of irrigation water was sufficient to fill the moisture-de...
