in some regions of isfahan, although there is no soil and water salinity limitations, quality of sugar beet root is very low because of using high amount of irrigation water. a study was conducted to determine the relation between low irrigation and quality and quantity of sugar beet. in this study, a line source irrigation system for six water use treatments (from 10770 to 8554 m3/hec) was use...

water stress decrease water content and water potential between soil and root. therefore, water potential  of plant declines and plant faces with water stress. water stress in different stages of growth can be useful in different aspects. water stress can be practiced from two point of view, increasing water use efficiency (wue) and improving cultural practices. no irrigation in insensitive sta...

this study carried out in a factorial layout on completely randomaized block design with three replications, to evaluate the above- and below- ground competition between sesame (sesamum indicum) and pigweed (amaranthus retroflexus), and their impacts on sesame yield and yield component. the experimental treatments were all combination of crop-weed competition (shoot competition, root competitio...

general combining ability of sugar beet parents were determined for different quantity and quality characteristics.forty six sugar beet hybrids obtained from crosses of 23 diploid pollinators with two male sterile parents as tester together with three checks were evaluated for 10 important agronomic and technological characters at kamalshar research station in karaj in 2004.experiment was carri...

in order to evaluate the effects of planting pattern on morphological, phonological, yield and yield components of sweet and super sweet corn (zea mays l.) varieties under saline conditions, a field experiment was conducted as split plots based on a randomized complete block design with four replications. planting pattern in 3 levels included one row in ridge, two row in ridge and furrow planti...
