Haruyuki Fujimaki, Vinay Nangia. (28/3/2017). Effect of simulated irrigation in wheat cultivation in Jordan. Tokyo, Japan.
To enhance net income from limited water resources, Fujimaki et al. (2014) presented a scheme for determining irrigation depth using a numerical model of crop response to irrigation and quantitative weather forecast. To optimize each irrigation depth, a concept of virtual income, which is proportional to an increment in transpiration amount during an irrigation interval, was introduced. Several field experiments applying this methodology have been carried out, but further case studies to various situation (combinations of climate, soil, and crop) are still required for validation and improvement of this methodology. The purpose of this study was to verify the methodology for wheat cultivation in semi-arid region in which the effectiveness of the methodology was expected to be significant.
