In a 3-year experiment (2002-2004), five N rates (0, 60, 120, 180, 240 kg N ha-1) were applied to sugar beets arranged in a Randomized Complete Block design with six replications. Experimentation took place under the semi-arid, irrigated conditions of central Greece. The aim of this work was to study the late season response of sugar beet crop to N fertilization as assessed by non-destructive m...

abstract the most important part of the design and operation of the supplier systems of agricultural water requirement is the estimating of plant water requirement. in this study by using the lars-wg5 model, downscaled the data of hadcm3 model according a1b, a2 and b1 scenarios that confirmed by ipcc, and was simulated monthly amounts of precipitation, minimum temperature, maximum temperature a...

in this paper, productivity of and demand for water throughout eqlid’s sugar beet growers in 1385 were investigated. to address the objective 100 growers were selected using two-stage cluster sampling, then required dataset was obtained by interviewing and completing questionnaire. in order to study factors affecting sugar beet production, cobb-douglas production function was applied. based on ...

in order to investigate the relationships of some morphological traits at the early stages of three sugar beet cultivars with final yield at varying levels of water regines, a field experiment was carried out in karaj, and mashhad, in 2001-2003.  the objective of this study was to find the relation of some morphological traits of three sugar beet genotypes (7219-p.69, bp-karaj and 7112)  during...

a field experiment was carried out during 2001 in the experimental fields of sugar beet seed institute in karaj. the objective of this study was to determine the response of some quantitative and qualitative traits of three sugar beet lines subjected to continuous water stress and normal conditions. three sugar beet lines 7219-p.69, bp-karaj and 7112 as tolerant, semi tolerant and sensitive to ...

Under surface irrigation, particularly in clay soils cut-off technique is considered as one of the most practical way in saving irrigation water that traditional farmers could be easily implemented. Such farming way is processing through find out the optimum length of irrigation run at which watering should be stopped instead of irrigation till the tail end of the furrows or borders. Such proce...
