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...

The article discusses the process of industrial crystallization sucrose, which includes three main stages (thickening syrup, formation centers and their growth). Depending on method crystal used, technologies for obtaining massecuite I were analyzed, improvement is due to conditions centers, growth, thickening masses separation in centrifuges. disadvantage considered methods heterogeneity sugar...

this study was conducted to determine the yield response factor (ky) of sugar beet to deficit irrigation at different growth stages. a field experiment was conducted in sharekord agricultural research station over two growing crop seasons (1996 -1997) using a randomized complete block design with three replications. plots were assigned to five levels of deficit irrigation treatments: e0 (full i...

This study aimed to analyze the seasonal dynamics of sugar beet leaf and root yield quality in different plant populations nitrogen fertilization rate. The field trials were set as four planting densities (60,000 140,000 plants ha?1) three spring rates: no fertilization, pre-sowing (45 kg ha?1 N), with top dressing (99 N 2014 85.5 2015. changes growth done measuring area (LA), index (LAI), spec...

in the present experiment, the effects of nitrogen and phosphor fertilizer application in two methods of furrow and trickle irrigation on the yield and quality of sugar beet seed cultivar 7233 were studied. the experiment was conducted as a split factorial in a completely randomized block design with three replications during 2003 and 2004 in hamedan province. main plots were allocated to irrig...

in order to evaluate the effects of sub soiling and irrigation level treatments on yield of sugar beet and wheat in rotation, an experiment was conducted at agricultural research station ofwest azerbaijanprovince. the plots were arranged as a strip plot experiment in randomized complete block design with three replications. horizontal plot (sub soiling treatment) consisted of sub soiling depth ...

in order to evaluate the effect of some qualitative traits of sugar beet (beta vulgaris l.) under irrigation water quality and different types of fertilizers, a field experiment arranged as split plot in rcbd design with three replications at research station of shahrekord university in 2013. the main factor include irrigation with urban wastewater at 2-4 leaf stage, 8-12 leaf stage and irrigat...

Two field experiments were conducted at the Desert Experimental Station of the Fac. of Agric., Cairo Univ. in Wadi El-Natroon, during 2012/2013 and 2013/2014 seasons to study the response of sugar beet yield and some of its attributes in three multigerm seed cultivars, viz. Heba, Ninagri and Halawa under drip irrigation in a split plot design to foliar application with zinc (Zn) + Manganese (Mn...

Conventional procedures are inadequate for optimizing the concentrations ofnutrients to increase the sugar yield. In this study, an artificial neural network(ANN) was used to optimize the Ca, Mg, N, K and Na content of the storage rootto increase sugar yield (Y) by increasing both sugar content (SC) and root yield(T). Data from three field experiments were used to produce a wide range ofvariati...

this study was conducted in split plot design based on a randomized complete block design in naghadeh region, urmia, iran in 2009-10. two sowing patterns including a1) single row planting with 50 cm between-row spacing, and a2) two rows planting on the hill with 40 cm distance and 50 cm between-row spacing (40×50) were allocated to main plots and four furrow compactions including b1) control, b...
