Iran with a cultivation area of 45000 ha and production of 150 ton/year is the number one saffron producer in the world. Planting of large size corms will increase flowering, but production of corms (number and size) may be affected by irrigation method or frequency. In this research which is performed in the farm of College of Agriculture, Shiraz University, the effects of method and frequency...

Infiltration is the most crucial process affecting surface irrigation uniformity and efficiency as it is the mechanism that transfers and distributes water from the surface to the soil profile. As a direct method of infiltration measurement, the volume balance method requires time, accuracy and high costs. Moreover, before the land preparation and at the research phase the use of this method is...

Rice production in sub-Saharan Africa has more than doubled in the last 3 decades and the potential to further develop rice-harvested areas is considerable. Several studies have demonstrated that the transformation of arable land into rice irrigation might create suitable habitats for large populations of disease vectors. Prominent among those are anopheline mosquitoes responsible for transmiss...
