the study was conducted during 2002- 2007 in the first and last stage of a four-year rotation (sugar beet, forage maize, onion, wheat and sugar beet) at research station of irrigation and drainage rudasht. in each year, four treatments of organic fertilizers (25 and 50 t/ha urban compost and 15 and 30 t/ha sewage sludge) with a control (no organic fertilizer) were studied in a randomized comple...

Objective: Many agronomic practices may need to be adjusted to maximize yield and quality of sugar beet. Thus agronomic package must be always modified. This sutdy was laid out for evaluation of changes in carbohydrates and sugar yield in sugar beet (Beta vulgaris L.) under different biofertilizers and irrigation closed time at Dorud region of Iran, during 2013. Methods: The experiment...

in order to study the effects of farm yard manure (fym), sulfate of potassium (sop) and boric acid on quality and quantity of sugar beet, an experiment was conducted in split plot factorial with four replications during 3 years (1999-2001) in bardsir- kerman. the fym was the main plot in 3 levels: 0, 10 and 20 ton.ha-1. sop was applied at levels, 0 ,75 and 150 kg.ha-1  and boric acid at levels ...

for determining sugar beet water requirements, this work was conducted at the  agricultural research station of torog in mashhad for 3 years. crop water requirement was measured by a drainage type lysimeter with dimension of 2*2*1 m. in order to reduce side effects, an area about 1600 m2 around the lysimeter (as a guard) was cultivated with sugar beet. soil water content was measured by tensiom...

sugarcane bagasse contains cellulose, lignin and hemicellulose, 39-42%, 20-25% and 25-27% respectively. so it is can be used as a sugar source in many processes. lignin and hemicellulose must be removed before hydrolysis of cellulose. several different pretreatment approaches have been studied. the purpose of this research is comparison of acid, ozone and combination of ozone-acid as pretreatme...

Sweet corn (Zea mays L.) producers desire high yields and high sugar content in the endosperm. High irrigation levels result in high yield, but their effect on sugar content is unclear. The effects of two irrigation levels, standard and stressed on endosperm sugar content were evaluated using three sugary1 hybrids over 2 years. No significant differences were found among the treatments when ave...

introduction crop productivity is highly constrained by water and nitrogen limitations in many areas of the world (kalra et al., 2007). therefore, there is a need to investigate more on nitrogen and water management to achieve higher production as well as quality. irrigated sugar beet in the cropping systems of khorasan province in northeastern of iran accounts for about 34% of the land area un...

This paper analyzes the impact of genes and proportional contribution of parental genotypes on the inheritance of root yield and sugar content in diploid hybrids of sugar beet. The survey included two diploid male-sterile monogerm lines and three single (SC) male-sterile hybrids as maternal components, while three multigerm diploids were used as pollinators. The partitioning of genotypic varian...
