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....

Climate is one of the most important factors that influence the quality and quantity of crops. Understanding the natural features of any region, especially about the climate, can play a major role in making plans and land use planning. Sugar beet, is one of the major industrial plants, that in addition to producing one of the most fundamental basic needs of society, namely sugar, it can have ot...

SUBEMOpo (SUgar BEet MOdel potential production) is a mechanistic simulation model to simulate sugar beet growth and sugar accumulation for potential production conditions. Under those conditions sugar beet growth and sugar accumulation are entirely controlled by the prevailing weather (radiation, temperature) and by the crop characteristics (plant density). The only site characteristic require...

seeds of nine sugar beet lines: five drought tolerant, two susceptible, and two medium tolerant were washed, sterilised, dried, and sown in water agar medium for germination test. seedling growth characters such as cotyledon fresh weight (cfw), cotyledon dry weight (cdw), root fresh weight (rfw), root dry weight (rdw), and root length (rl) were determined after the end of 28 days period of expe...

Autumn sowing of sugar beet is a suitable way in sustainable agriculture. Bolting is an undesirable phenomenon which reduces sugar beet yield and it is the most important limiting factor in autumn sowing of sugar beet. Identification and comparison of the sequence of flowering genes in various genotypes can help to understand the molecular mechanisms controlling bolting. In the previous studies...

Broiler chickens were fed on a control diet based on maize or on diets including conventionally-dried (standard pulp) or vacuum-dried (Fipec pulp) sugar-beet pulp at inclusion levels of 23, 46 and 92 g/kg. Diets were fed ad lib. except for half of the chickens fed on the control diet which were fed twice daily at a restricted level. Although not statistically significant, chickens given the 23 ...
