This study investigated the interactive effects of different rates of deficit irrigation and timings of N application on wheat and barley yields since there was no report on this important subject. Field experiments in strip-plot designs using sprinkler line sources were conducted for two years at a semi-arid Mediterranean site. The experiments consisted of 4 and 7 irrigation levels with 3 and ...

Manure management is an integral concern of Florida dairymen. Wastewater from nine dairy sprayfields on seven north Florida dairies with overhead sprinkler or gun irrigation facilities was collected biweekly from early September 1992 to Janu­ ary 1993. Samples were taken from the pump area of either anaerobic lagoons or settling ponds, rainfall, and from effluent plus rainfall in sprayfields. A...

Since being released 40 years ago, computer spreadsheets have proven to be worthwhile for use in educational contexts. There is plenty of evidence this practically every scientific discipline and engineering field. In view on fact, the present work exposes a didactical resource, named sprinkler irrigation tool, developed Excel® spreadsheet licensed by 2018 Microsoft©. The objective tool offer a...

Literature regarding evaporation from soil, wet plant surfaces, and sprinkler droplets was examined, normalized, and inter­ preted. Much of the evaporation literature is difficult to compare and interpret; this paper offers comparisons and discussions of various findings by others as well as by the writers. Techniques of measuring and estimating evaporation from irrigation and rainfall are disc...

Abstract Traditional rice ( Oryza sativa L.) cropping systems under flooding irrigation combined with conventional tillage management are increasing threat due to a loss of soil quality and scarcity water resources, especially in Mediterranean environments. Hence, the development such strategies as no-tillage, application organic amendments, water-saving methods could be vital enhancing sustain...

Preserving the sustainable agriculture concept requires identifying plant response to water regime and rationing for irrigation. This research compares different irrigation designs coupled with a parametric evaluation system on soil erosion suitability assess sites vulnerable based model (ImpelERO) in an area of 150.0 hectares, Ismailia Governorate, Egypt. Land maps are prepared using Geographi...
