Background Under field conditions, the development of crops depends on capacity of the canopy to intercept incident radiation and convert it into new biomass (Gifford et al. 1984). The amount of incident radiation intercepted depends on the leaf area index (LAI) and canopy orientation in space. The fraction of the incident photosynthetically active(More)
Effective management of water under irrigated agriculture is crucial to ensure food security. One crop that has high irrigation economic potential at local and international scales is soybean. This article presents the outcome of field experiments conducted in the dry seasons of 2013 and 2014 in Nigeria on the effects of deficit irrigation (DI) practices on(More)
In the Sudanian climate zone of West Africa (more than 900 mm/year of rainfall), the valley bottom rice fields are characterized by a persistent low yield (less than 4 tons/ha) caused by poor internal drainage according to many researches. The groundwater table has raised to less than 30 cm below ground surface level in many recent irrigation schemes like(More)
Under rainfed agriculture without supplementary supply, crop failure due to erratic rainfall has become a common phenomenon in many regions of Ethiopia. Spate irrigation development with storage provision at the 5,000 ha Boru Dodota Spate Irrigation Scheme is one of the initiatives to move away from exclusively rain-dependent agriculture. This initiative(More)
