In this paper, we present the results of our study on the operational application of the reflectance-based crop coefficient for assessing table grape irrigation requirements. The methodology was applied to provide irrigation advice and to assess the irrigation performance. The net irrigation water requirements (NIWR) simulated using the reflectance-based basal crop coefficient were provided to ...

Although the term precision irrigation is now quite widely used, often to mean drip irrigation, there is no commonly accepted definition or conceptualisation of the term, and no cohesive framework to guide research, development or adoption. This paper is reporting on a review of precision irrigation funded by NPSI. This review is considering the role of current irrigation application technologi...

introduction: lack of water and deterioration in the quality of soil and water resources are considered to be the prime cause of reduced crop yield in arid and semi-arid regions ‘more crop per drop’ by trickle irrigation, deficit irrigation, and uncommon water are the best strategies for mitigating water crises. different irrigation management strategies are needed to increase production in dif...

this study was conducted to evaluate the impact of deficit irrigation and growth stages on yield and yield components of potatoes and water use efficiency. a field experiment was conducted at shahrekord agricultural research station over three years of crop seasons using a randomized complete block design with three replications. plots were assigned to five levels of deficit irrigation treatmen...

present limitations on available water resources especially for use in agriculture sector, shows that more attention to irrigation water management is inevitable. deficit irrigation is a practice to improve use of unit volume of water. in this research, efficacy of cropwat 8.0 model was evaluated against field data under deficit irrigation management on soybean in karaj. in 2008 and 2009 agrono...

     For investigation deficit irrigation and nitrogen application effect on nutrients uptake of henna ecotypes, this research was conducted in the form of split-split-plot on the basis of randomized complete block design with four replications in the Research Field of Islamic Azad University, Jiroft, Iran in 2013-2014. The main, sub and sub-sub plot were deficit irrigation (100, 75 and 50% of ...

Purpose This study set out to identify the association between the intraperitoneal CO2 concentrations and postoperative pain by dividing the participants into a control group and 2 experimental groups receiving irrigation (1 L and 2 L), and directly measuring their intraperitoneal CO2 concentrations with a CO2 gas detector. Methods A total of 101 patients, American Society of Anesthesiologist...

to investigate the effects of regulated deficit irrigation (rdi) on the growth, yield and quality of ‘yali’ pears, field experiments for c (fully watered control), ew [early withholding of irrigation, water stress from pullulation to 25 days after flower bloom (dafb)], mw (mid-growth withholding of irrigation, water stress from 25 dafb to 80 dafb), and lw (late withholding of irrigation, water ...
