in this study, analysis of actual data collected from sugar beet hybrid monogerm seed producers in the 2001 growing season and laboratory seed samples showed that delay in steckling sowing resulted in the reduction of raw and pure sugar beet seed yield and the increase of undersize seed portion. non-significant effect of sowing dates on unkernel seed percent showed that the high temperatures wi...

water stress is one of the main factors affecting the quantity and quality properties of sugar beet. the objective of this experiment was to study the effect of irrigation management on quality and quantity of sugar beet. the present research was conducted in motahary station of sugar beet seed institute,karajin two years, 2005 and 2006. the experiment was based on split plot design, in which e...

Sugar juices in the production of beet sugar contain complex varieties of colored materials that have not been identified completely. Color of the sugar depends the color of juices from which sugar is produced. The mechanisms concerning color formation in beet sugar processing are complicated due to many parameters involved. The main mechanisms related to the color formation during purification...

Russia, Ukraine and Kazakhstan are the leading agricultural producers, especially for potato, sugar beet and sunflower. The cumulative effect of adverse climatic conditions, high weediness and losses related to viruses and pests (without any insecticide and herbicide treatments) led to losses amounting to 40-80% of potential production in the Russian Federation and other mentioned countries. We...

this research was carried out to evaluate the effects of some morphophysiological traits on white sugar yield of 10 commercial sugar beet (beta vulgaris l.) varieties. all experiments were conducted in four important sugar beet growing areas in iran, i.e. moghan, khoy, karaj and zarghan in 2006 and 2007. the experiment was arranged as a randomized complete block design with three replications i...
