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...

water is one of the most important restrictive factors in crop production. therefore, optimum use of water resources in line with sustainable agriculture is mandatory. in this research the effects of different amounts of allowed soil water depletion at various growth stages of root sugar beet and its effect on qualitative and quantitative characters of the crop were studied. the experimental de...

for continues production if field crops in arid and semi arid regions of the world, such as iran, beside of using of drought resistant varieties, water management must also be considered. in this context, the use of tape drip irrigation system could reduce the amount of irrigation water consumption. this study, was conducted to determine the best sowing pattern of sugar beet under type drip irr...

Enzymatic synthesis of sugar fatty acid esters was performed in an organic solvent using an immobilized Candida antartica lipase and various sugars and oleic acid as substrates. A high solubility of the sugar in the solvent was needed for a high sugar ester yield. Among the sugars and solvents tested in this study, the highest yield (98 %) was obtained when xylitol and 2-methyl 2-butanol were u...

Sugar beet fertilization is a very complex agrotechnical measure for farmers. The main reason that technological quality equally important as sugar yield, but the increment of root yield does not follow quality. Technological implies concentration sucrose in and possibility its extraction production white table sugar. great variability agroecological factors directly affect are possible good ag...

this experiment was conducted in five regions of spring sowing of beet cultivation as follow: karaj, hamadan, shiraz, miandoab and mashhad for three years. five levels of potassium (0, 50, 100, 150 & 200 kg/has) from k2so4 source were applied before sowing. the experiment design was crbd design with five replications. the results showed that both root yield and sugar yield were affected signifi...

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...

introduction: weed competition is one of the major factors which limit sugar beet production in the world. weed – crop interactions are based on competition for water, nutrients and light and allelopathic effects may also play a small role. in sugar beet weed interference, all these factors are important too, but the light is of prime importance. due to the fact that a lot of weeds can grow abo...

one of the most effective ways to deal with drought stress and increase water use efficiency is the development of drought-tolerant varieties which display less reduction in yield per unit water reduction. therefore, the breeding of diploid pollinators was considered as an essential measure for producing drought-tolerant hybrids. in this study, from 4 diploid pollinator populations, 45 half-sib...

The study was conducted in Sudanese Sugar Industries during the period 2017 to aim determination some heavy metals and microbial profiles of raw samples collected from season relation EU.1998 ICUMSA,1974 standards. were obtained all namely, (Kenana, White Nile, Assalaya, Sennar, Guneid, New Halfa). After that transferred laboratory assess quality parameters sugar which include content cane per ...
