in semiarid regions of iran, one of the crop production management methods is delayed irrigation after emergence. this is due to simultaneous water requirement of cereal and spring season crops. a field study was conducted in kabootarabad research station to investigate the effect of delayed irrigation on root yield, quality and growth trend using a rcb with four replications. the irrigation tr...

in order to apply suitable methods for sugar beet seed sowing and determine the relation between yield and growth parameters in saline soils, two salt tolerant progeny lines were sown by five methods for two years (1995 and 1996) using a split plot design. growth parameters such as leaf area index, crop growth rate, total dry weight and relative growth rat were analysed. ph and ec of the soil a...

in the present study, twenty two selected lines from eleven iranian eggplant (solanum melongena l.) landraces along with varamin landrace, as control, were studied in a randomized complete block design with three replications in three locations (karaj, varamin and dezful). sum of yield and marketing score for each line was recorded. analysis of variance for yield showed significant differences ...

Water stress causes defoliation, which can reduce yield and root quality of sugar beets (Beta vulgaris L.) through altered gas exchange characteristics of the leaves. In a two-year experiment, three sugar beet cultivars (Europa, Rival and Corsica) were subjected to three defoliation levels (control-C, moderate-MD, severe-SD) and re-watering after their exposition to drought for a month. Leaf ph...

for continues production if field crops in arid and semi arid regions of the world, such as iran, beside of using of drought resistant varieties, water management must also be considered. in this context, the use of tape drip irrigation system could reduce the amount of irrigation water consumption. this study, was conducted to determine the best sowing pattern of sugar beet under type drip irr...

An investigation was undertaken to study the feasibility of sugarbeet cultivation under Bangladesh condition during winter season of 2009-2010. Seeds of 14 sugarbeet genotypes were sown in the experimental field of Horticulture Research Centre of BARI, Gazipur on 10 November 2009. Visible root swelling in all genotypes started between 36 and 40 days after sowing (DAS). Nine genotypes had white ...

this study was conducted in split plot design based on a randomized complete block design in naghadeh region, urmia, iran in 2009-10. two sowing patterns including a1) single row planting with 50 cm between-row spacing, and a2) two rows planting on the hill with 40 cm distance and 50 cm between-row spacing (40×50) were allocated to main plots and four furrow compactions including b1) control, b...

introduction crop productivity is highly constrained by water and nitrogen limitations in many areas of the world (kalra et al., 2007). therefore, there is a need to investigate more on nitrogen and water management to achieve higher production as well as quality. irrigated sugar beet in the cropping systems of khorasan province in northeastern of iran accounts for about 34% of the land area un...
