Soil surface resistance increase quickly during the first three days after irrigation or rain event. By explicitly incorporating surface resistance in simple equations, daily total evaporation estimation of a drip-irrigated olive grove was significantly improved. This increase in soil surface resistance could explain why observed cumulative soil evaporation is higher in locations with lower irr...

In order to assessment of SDI system application in the condition of wastewater reuse, three treatments with three replications were design. These treatments included check treatment with drinking water (CH), surface drip irrigation with wastewater (DI) and subsurface drip irrigation with wastewater (SDI). In addition, before pipeline, a SDI filtration designed to improve biological index of wa...

The Cal Poly ITRC irrigation evaluation programs have been widely used to assess the global distribution uniformity (DU) of drip and microsprayer irrigation systems. The field procedures and formulas used in the program are presented in this paper. The system DU is estimated by mathematically combining the component DU values. DU components include pressure differences, "other causes" (such as ...

Aflatoxins are secondary metabolites produced by Aspergillus flavus, A. parasiticus, A. tamari, A. bombycis and A. nomius species. Relative humidity (RH) is one of the most important parameters influencing the development of aflatoxins in pistachio orchards by Aspergillus species. The type of irrigation system affects density and frequency of the Aspergillus species in the soil. In the current ...

Providing the population with clean drinking water and agricultural water, which provides humanity food, has become one of main problems around world. In Republic Uzbekistan, as well in other countries world, shortage is growing every year. The article states that factors for mitigating shortages agriculture introduction water-saving technologies. Among technologies, most effective system drip ...

Water is essential for life. Specifically in the oases of inland arid basins, water is a critically limited resource, essential for the development of the socio-economy and the sustainability of eco-environmental systems. Due to the unique hydrological regime present in arid oases, a moderate groundwater table is the goal of sustainable water management. A shallow water table induces serious se...

Meeting the food needs of Africa's growing population over the next half-century will require technologies that significantly improve rural livelihoods at minimal environmental cost. These technologies will likely be distinct from those of the Green Revolution, which had relatively little impact in sub-Saharan Africa; consequently, few such interventions have been rigorously evaluated. This pap...

A drip irrigation delivery system was used to infest field sites with the plant-parasitic root-knot nematodes, Meloidogyne incognita. Juvenile or egg inocula passed through the system without blockage of emitters or harm to the nematodes. Field sites so infested were available for experimentation. Delivery of approximately 5 x 10 to 10 juveniles or 10 to 3 x 10 eggs per emitter through the drip...
