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...

the root pulling force as well as the amount of transferred soil have not been reported quantitatively for various sugar beet types. this study was designed to measure the amounts of transferred soil from farm and estimate the root pulling force among sugar beets populations with different root shapes at harvest time. the experiment was conducted as a split plot with a randomized complete block...

in order to evaluate the efficiency of empirical competition models for simulation of sugar beet (beta vulgaris l.) yield at interference with redroot pigweed (amaranthus retroflexus l.), a factorial experiment based on randomized complete block design with three replications was carried out. factors were weed densities (d1=1, d2= 4, d3= 8, d4=12 and d5=16 plants m-1 of row) and relative time o...

to determine sugar beet water requirement and the effect of changing the quantity of applied water on some production components, a study was carried out in ekbatan agricultural research station of hamedān, iran in four years (1994-1997) during which optimum water requirement, root and sugar yield, water use efficiency on the basis of root yield, sugar percentage and water use efficiency on the...

in this study, the performance of different cultivation methods on sugar beet fields was evaluated. eight treatments were considered: a) use of a rolling cultivator twice during the growing season; b) use of a rolling cultivator three times during the growing season; c) use of a crescent cultivator twice during the growing season; d) use of a crescent cultivator three times during the growing s...

to determine sugar content and root yield variation of new sugar beet hybrids under different irrigation levels, an experiment was carried out at zarghan agricultural research station offars agricultural and natural resources research center, shiraz, iran. the study was conducted as split block based on a randomized complete block design with three replications for two years, 2009-10, using lin...
