abstract in order to evaluate the effects of different depths of irrigation by sprinkler irrigation system on water use efficiency (wue) of new early maize cultivar ksc302, an experiments was carried out in karj during 2006 and 2007. experimental design was split plot based on randomized complete blocks with three replications. main plots were three irrigation levels: 75%, 100% and 125% etc (es...
Many recent reviews and meta-analyses of N2O emissions do not include data from Mediterranean studies. In this paper we present a meta-analysis of the N2O emissions from Mediterranean cropping systems, and propose a more robust and reliable regional emission factor (EF) for N2O, distinguishing the effects of water management, crop type, and fertilizer management. The average overall EF for Medi...
Drip irrigation is one of the new irrigation methods for optimum use of water resources and increase of irrigation efficiency. The emitters' clogging is the most important problem in these systems. The physical clogging is the most important factor in reducing the discharge and emission uniformity of emitters. The emitter position on the laterals and emitter spacing are the factors that affect ...
water shortage in the agricultural sector is currently a major challenge in crop production. the more efficient water usage is that which increases yield without increasing water use. thus, a determination of the water-yield relationship is essential. a field study was conducted to examine water-yield relations in three genotypes of soybeans, including optimum irrigation depth, a comparison of ...
system evaluations were performed on 48 center pivots in different parts of saudi arabia. these systems, located on different farms in four different regions of the country, namely: riyadh, jouf, qassim and eastern regions, were evaluated to study the effect of lateral configuration on water application uniformity as regards the original vs. modified laterals. lateral configuration modification...
Title of Thesis: A POTENTIAL FLOW MODEL OF A FIRE SPRINKLER HEAD Taylor Myers, Master of Science, 2014 Dissertation directed by: Professor André Marshall Department of Fire Protection Engineering Understanding fire sprinkler sprays fills a critical gap in the modeling of fire suppression systems. Previous research has shown that a modeling framework consisting of an instability model coupled wi...
Cotton (Gossypium hirsutum L.) yield and quality responses to irrigation have not been described for conservation management systems that growers are rapidly adopting. We conducted a field experiment from 2001–2003 in the Tennessee Valley near Belle Mina, AL on a Decatur silt loam (fine, kaolinitic, thermic Rhodic Paleudults) to examine how irrigation regimes and tillage systems affect ginning ...
Several previous studies have highlighted the irrigation-induced impacts on global and regional water cycle, energy budget, near-surface climate. While land models are widely used to address this question, implementations of irrigation in these vary complexity. Here, we expand representation CLM enable six different methods. We find that using a combination methods, including default, sprinkler...
Schirmer Engineering Corporation (Schirmer Engineering) was retained by The Fire Protection Research Foundation (FPRF) as a Project Consultant for the project titled “Data Needs for NFPA Automatic Sprinkler Committees.” This report investigates the NFPA 13, Standard for the Installation of Sprinkler Systems (2007 Edition) requirements for dry pipe systems having a maximum volume of 500 gallons ...
