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...

the use of organic fertilizer brings about an increase in the organic matter of soil and the microbiological activities. generally as the soil in many parts of iranis poor, the use of manure is suggested for improvement of soil structure and physical and chemical properties to increase yield and to reach a sustainable agriculture. this investigation was conducted during 2001-2004 in karaj at th...

___________________________________________________________________________________________ Abstract In commercial ethanol production producers often use sugarcane or sugar beet molasses as raw material due to their abundance and low costs. The most employed microorganism used for fermentation is Saccharomyces cerevisiae yeast due to its ability to hydrolyze sucrose from cane or beet molasses i...

in order to determine the optimum sowing and harvesting dates of two autumn sugar beet cultivars (bete vulgaris l.) and develop the planting area of this crop, the present research was conducted in fasa, iran during 2005-2008. the experiment was carried out in split-split plots based on randomized complete block design (rcbd) with four replications. three sowing dates (september 27, october 17 ...

in order to study the possibility of control of heterodera schachtii  in sugarbeet fields through integration of rotation with non- host crops and resistant catch crops and their effects on quantitative and qualitative traits of sugarbeet, this study was started from 2002 for three years in esfahan province. the experiments were carried out in a randomized complete block design with eight treat...

Background Optimum potassium (K) nutrition is essential for high sugar yield and quality of beet crops. Aims We quantified the effect deficiency on dry matter formation during growing season. Methods Sugar beets were grown low, medium, soil K concentrations in a long-term fertilizer field experiment silt loam alluvial soil. Plants harvested at four time points season, including final harvest. A...

this experiment was conducted to evaluate eight new sugar beet genotypes with different drought tolerance responses to three irrigation schemes (including normal irrigation and early season and continuous stressed) in motahari research station of sugar beet seed institute (sbsi),karaj,iranduring 2005-2006. the study was accomplished in a split plot design (irrigation schemes and genotypes as ma...

Sugar beet (Beta vulgaris ssp. vulgaris) is a biennial, sucrose-storing plant, which is mainly cultivated as a spring crop and harvested in the vegetative stage before winter. For increasing beet yield, over-winter cultivation would be advantageous. However, bolting is induced after winter and drastically reduces yield. Thus, post-winter bolting control is essential for winter beet cultivation....

short growing season in cold regions is an important factor in not achieving a maximum root yield in sugar beet crop. in an investigation on possible ways to limit the effect of short season culture on the crop, six harvest dates and three sugar beet varieties were considered. the experiment was conducted as a factorial with randomized complete block design in three replications, from 1996-1998...
