Irrigation systems are as old as man itself since agriculture is the foremost occupation of civilized humanity. To irrigate large areas of plants is an onerous job. In order to overcome this problem many irrigation scheduling techniques have been developed which are mainly based on monitoring the soil, crop and weather conditions. Irrigation scheduling engrosses when to irrigate and how much wa...

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 ...

Rangeland plant productivity and species composition are affected by moisture availability and grazing intensity. We examined warmand cool-season grass productivity and relative distribution on grazed and ungrazed sites, receiving either natural precipitation or precipitation plus limited supplemental irrigation. The amount of additional water varied depending on rainfall during the previous we...

To improve agricultural water resources’ utilization, crop’s automatic, locate, time and appropriate drip irrigation is a good choice. In this paper, an automatic control drip irrigation system based on ZigBee wireless sensor network and fuzzy control would be introduced. System uses CC2430 for wireless sensor network node design, collecting soil moisture, temperature and light intensity inform...

in order to investigate the effect of nitrogen fertilizer on tea yield and yield components in supplemental irrigation and rain fed conditions an experiment was conducted at feshalam tea research station in fouman (guilan) during (2008-2010). in this study, line-source irrigation technique and the strip plot experiment on randomized complete block design was used. six levels of nitrogen, zero, ...

AIM To evaluate the antimicrobial effect of a diode laser irradiation, photo-activated disinfection (PAD), conventional and sonic activated irrigation with 2.5% sodium hypochlorite (NaOCl) on Enterococcus faecalis. METHODOLOGY Root canals of 120 human extracted teeth with single straight canals were prepared with ProTaper files, sterilized, contaminated with an E. faecalis suspension and incu...

To evaluate the effects of iron application on growth characters of Calendula officinalis L. under end season water deficit condition, an experiment was conducted as split plot at the Research Farm of Faculty of Agriculture, Urmia University (latitude 37.53°N, 45.08°E and 1320m above sea level), Urmia, Iran in 2010. Treatments were irrigation (irrigation disruption at first, second, third harve...

During the 2003 and 2004 growing seasons, research was conducted on a 'Providence' creeping bentgrass (Agrostis stolonifera L.) sand green at the University of Minnesota St. Paul campus to evaluate the use of ECH20 capacitance soil moisture sensors and FAO 56 ET (Food and Agriculture Organization of the United Nations Evapotranspiration) estimation in scheduling turfgrass irrigation by applying...

sustainable economical production of tea depends on the proper use of water and fertilizer. for this purpose, the role of supplemental irrigation and nitrogen fertilizer on economical production of tea plantations was studied by assessment of yield, production function, water use efficiency, and benefit/cost ratio, and final return in a field experiment at feshalam tea research station in fouma...

Insufficient water is the greatest limitation to crop production and choice of crops grown in the Northern Great Plains. Supplemental irrigation can overcome this limitation. Uncertainties about the drainage capacity of flne-textured subsoils and the effect of irrigation on soil properties has impeded irrigation development. In this study we quantified salinity changes in soils with fine-textur...
