Crop coefficients (Kc) are important for the development of irrigation schedules, but few studies on Kc focus on saline soils. To propose the growth-stage-specific Kc values for sunflowers in saline soils, a two-year micro-plot experiment was conducted in Yichang Experimental Station, Hetao Irrigation District. Four salinity levels including non-salinized (ECe = 3.4–4.1 dS·m–1), low (ECe = 5.5–...

Agricultural drainage water could be a source of water for irrigation in Egypt. A case study of an agricultural drainage water near ElDare region – Borg El Arab City Alexandria, Egypt. Some Physical and chemical parameters (pH, temp, TDS, DO, EC, Salinity, NO3–N, Cl ) were measured on site during seasons of 2014, 2015. By statistical analysis from Min, Max, range, mean, SD and median a performa...

The salinity tolerance of golden barrel cactus (Echinocactus grusonii), ocotillo (Fouquieria splendens), saguaro cactus (Carnegiea gigantea), and Gentry’s agave (Agave parryi truncata) was tested. Plants were irrigated with a solution of EC 0.6, 5.0, 10.0, and 15.0 dS/m. Duration of treatments were 18 weeks for saguaro and 26 weeks for the other three species. In general, fresh weight, dry weig...

mates of the temporal and spatial root water uptake patterns are needed. Quantification of root water exAlthough solutions of multidimensional transient water flow can traction rates also contributes to an improved underbe obtained by numerical modeling, their application may be limited in part as root water uptake is generally considered to be one-dimenstanding of chemical fluxes in the vadose...

Increased tomato fruit quality in response to increased salinity is well documented (Li, 2000). However, the increased fruit quality is achieved at the expenses of severe yield losses mostly due to reduced fruit size (fresh weight) and increased incidence of physiological disorders such as blossom end rot (BER). The ability to minimize the negative effects of high salinity at the root level, wh...

This paper describes a wireless sensor network that monitored water extraction rate, salinity and water table level. The network collected real-time water quality measurements in order to investigate the impacts of current irrigation practice on the environment, in particular underground water salination. Particular challenges included a large coverage area, a sparse network with mean link dist...
