Abstract (sommario):
Irrigation efficiencies are the indices that indicate how best the water applied to the farm is being utilized. These parameters are needed to know the performance of the irrigation activity on the farm. A low value of the irrigation efficiencies, in general, implies that land, water and crops are not being managed properly. The consequence of poor irrigation efficiencies are loss of crop and wastage of nutrients and water. The major factors which affecting irrigation efficiencies are irrigation system design, quality of land preparation, selection of irrigation methods, soil texture, soil dep

Abstract (sommario):
An irrigation scheduling program has been developed for zucchini squash that produced high yields and high water use efficiency with, a minimum number of irrigations. The irrigation program is based upon a soil water balance model developed by the USDA. This irrigation program is available in diskette form and may be used with any IBM compatible personal computer provided wind run, temperature, solar radiation, humidity and precipitation data are available.

Abstract (sommario):
AbstractThe effect of irrigation system uniformity on the selection of risk-efficient irrigation strategies is evaluated using crop simulation and stochastic dominance procedures. Alternative strategies are evaluated under assumptions of both uniform and non-uniform application. Results indicate that the variability of net returns resulting from the employment of a specified schedule increases when irrigation uniformity is explicitly represented. Solutions derived using economic efficiency and stochastic dominance criteria indicate that the uniformity with which irrigations are applied contrib

Abstract (sommario):
The main scope of the paper is to make an empirical analysis regarding the relationship between irrigation and efficiency in agriculture sector, the use of water in irrigation and the share of agriculture sector in GDP related to European and world environmental policies, in the frame of water resource management and climate change conditions. We concluded there is a shy relationship between irrigation and agriculture crop. Furthermore, irrigation has no significant effects on GDP. The study is based on data collection using EUROSTAT and Romanian databases. We conclude that water management re

The field experiments were conducted at the research farm of the College of Agricultural Engineering and Technology, Junagadh Agricultural University, Junagadh, Gujarat, India, during two successive winter seasons 2013-14 and 2014-15, to study the effect of high discharge drip irrigation on yield, water use efficiency and yield attributes of wheat (variety GW-366) crop in clay loam soil of semi-arid region. Irrigation regimes with 20 %, 40%, 50%, 60% MAD of ASW by drip irrigation and control as a surface irrigation as per farmer practices were subjected to randomized block design (RBD) for sta

Abstract (sommario):
The effects of various irrigation strategies applied with drip system and different planting dates on yield, components and water use efficiency of chickpea (Cicer arietinum L.; var. Inci), were evaluated during 2010 and 2011 under Mediterranean conditions. The treatments included full irrigation (FI), mild deficit irrigation (DI-75), severe deficit irrigation (DI-25), partial root-zone drying (PRD-50), and non-irrigated (DRY) for winter and spring planting times. DI-75, PRD-50, and DI-25 received irrigation water 75, 50, and 25% of full irrigation, respectively. Both irrigation regimes and so

Abstract (sommario):
One of the most essential inputs for agriculture is water. Moisture stress at critical growth stages in wheat severely effects the growth and yield. Hydrogel (water-absorbing polymer) can keep the appropriate moisture level at the root zone depth and protects the crop from adverse effect of moisture stress. The present trial was conducted during rabi season of 2020-21 to assess the performance of different hydrogels under different levels of irrigations on growth, yield, and water use efficiency of wheat. Results revealed that application of 3 irrigations recorded significantly maximum number

Abstract (sommario):
Water deficit, especially during summer, is currently one of the most important stress factors that influence olive oil production in olive orchards. A precision irrigation strategy, based on daily trunk growth, was assessed and compared with one continuous deficit, one full irrigation, and two different regulated deficit irrigation strategies. All of them were tested in a super high-density olive orchard located in northeast Spain, in which oil production, main oil production components, applied irrigation water, and water productivity were assessed. For this purpose, the crop was monitored f

Abstract (sommario):
Village tanks in some parts of India, particularly in dry zones, have been one of the most important water resources on which the rural communities depend on for their livelihood. Though these traditional water harvesting structures provide a number of services like drinking water and protective irrigation, their importance and contribution declined during the post-independence period. Recognising the importance of irrigation tanks for agricultural development, the central government and some state governments of India have taken various irrigation development programmes like tank rehabilitati

Abstract (sommario):
Since eucalyptus is a fast-growing plant, it offers advantages in comparison to other forest species, and the use of localized irrigation systems can increase yield and reduce time to cutting. The aim of this study was to evaluate two eucalyptus hybrids, growth in crop condition: irrigated and dry land, during the first year of development of the crop. The experiment was set up in April 2011 in the irrigation experimental area of the State University of Mato Grosso do Sul, in the municipality of Aquidauana, Mato Grosso do Sul, Brazil.
