Rhizosphere hypoxia constrains plant growth, and numerous studies have shown that root zone aeration accelerates photosynthesis growth increases crop yields. Nevertheless, the mechanism by which soil microorganisms are involved in this process is not clear. The purpose of present study was to examine effects irrigation depth on composition structure rhizosphere fungal communities tomato perform...

Agricultural productivity in irrigated areas depends on several factors, including the design and maintenance of irrigation systems. Excessive or insufficient applications water affect plant growth development, hence agricultural productivity. For this reason, evaluation system is essential to avoid loss during application. This study aimed evaluate efficiency uniformity a subsurface drip sugar...

The effects of drip irrigation and different cultivation methods on seedgermination and growth of Puccinellia tenuiflora in saline-sodic soils wereinvestigated in field experiments during 2008-2010 in the Songnen Plain, China.Drip irrigation was applied to waste saline-sodic P. tenuiflora grasslands for bothflat and ridge cultivation methods. Drip irrigation affected the distributions ofelectri...

Realizing the internal flow visualization inside the drip irrigation emitter is the basis of optimizing the labyrinth path structure and promoting its anti-clogging capability. The Computational FluidDynamics (CFD)method has become an effective approach to research the water movement in the labyrinth path of the drip irrigation emitter. In this paper, the standard k-ε model and the Large Eddy S...

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...

in order to investigate the effect of domestic wastewater and normal water (well water) on soil chemical properties and alfalfa yield, a research project was conducted for three years in chahartakhteh research station. the experiment was performed in randomized complete blocks design including four treatments in three replications. treatments were as follows: t1: irrigation with normal water at...

this study was conducted to determine the possibility of a crop water stress index (cwsi) to schedule irrigation for pistachio tree under subsurface drip irrigation. the effects of two irrigation intervals consisting 3 (i3) and 14 (i14) days based on measuring soil water content were investigated on the cwsi. from 22 may (doy 143) to 22 september (doy 266), the evapotranspiration in i3 and i14 ...
