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...
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...
the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
abstract plant species differ in their ability to grow at low available p soils in other words, plant species differ in p use efficiency at low p supply. this ability can be investigated by comparing p uptake efficiency of plants and relative effective factors. a pot experiment was carried out in the growth chamber and sugar beet, maize and groundnut were grown in a low available p soil in a co...
Agricultural insurance is one of the appropriate ways to overcome the risk in agricultural production and to increase farmers’ income security. In this study, the influence of wheat insurance, as personal-free insurance, and sugar beet insurance, as group-forcible insurance, on farmers’ risk attitudes in Fars Province were investigated as a case study. Data were collected using stratified multi...
ethanol is a clean and renewable energy source. the necessity of ethanol usage, instead of fossil fuels or mixed with them, in order to reduce environmental pollution resulted in increase of ethanol production from 50 million m-3 in 2007 to 85 million m-3 in 2012. the present study aimed to compare the cost of bio-ethanol production from sugar beet with other agricultural crops, and also econ...
Molasses is a significant by-product of sugar beet or sugar cane refining industry. In this work, the effects of storage temperature and packaging on the contents of free amino acids (AAs) in sugar beet and sugar cane molasses after freeze drying were inquired. The effect of different variables such as, temperature (4 and 25˚C) and light (Metallized polypropylene container and Normal polypropyl...
this research was conducted to examine the effect of a concurrent training on rest level of leptin of plasma and some hormonal factors in non-athlete subjects. the research population included non-athlete men who didn’t participate in any organized sport activities. 30 men were chosen voluntarily among the above-mentioned population and were divided into 2 groups: experimental (15 subjects) an...
in process of sucrose determination in sugar beet, pulp analysis by polarometric method is done on the basis of fresh root weight .the volume of the juice of 26 grams of the pulp is considered 23 ml that with 177 ml of clarifying agent would be 200 ml. drought stress and dehydrated root reduce. the volume of the pulp extract of 23 ml. the objective of this experiment was to determine the proper...
The thermostable enzyme systems produced by the thermophilic ascomycete fungus Talaromyces emersonii cultivated on various carbon sources were investigated for the production of high value products from sugar beet. A broad range of enzymatic activities relevant to cellulose, hemicellulose, and pectin hydrolysis were identified in T. emersonii culture filtrates. In hydrolysis experiments conduct...
