The discrepancies across test sites and years, along with the interaction between cultivar and environment, make it difficult to accurately evaluate the differences of the sugarcane cultivars. Using a genotype main effect plus genotype-environment interaction (GGE) Biplot software, the yield performance data of seven sugarcane cultivars in the 8th Chinese National Sugarcane Regional Tests were ...

one of the biggest barriers for agricultural production in iran is water deficit. however, certain optimum approaches for water application can solve this problem. deficit irrigation technique is an approach that could have a better and economic use of water in agriculture. in this regard, a research with three factors including two irrigation intervals of 8 and 12 days, two nitrogen fertilizer...

to determine sugar content and root yield variation of new sugar beet hybrids under different irrigation levels, an experiment was carried out at zarghan agricultural research station offars agricultural and natural resources research center, shiraz, iran. the study was conducted as split block based on a randomized complete block design with three replications for two years, 2009-10, using lin...

in order to investigate the impact of government policies on supply, cropping area and yield of sugar beet during 1981-2003, nominal rate of protection (nrp) was applied as a variable to persuade government’s policies in this study. results showed that despite of its negative impacts on cropping area, the nrp has positive effects on supply and yield of sugar beet iniran. moreover, real price of...

autumn planting of sugar beet as compared to its spring cultivation demands less application of water in semi-arid region such as iran. therefore, cultivation of sugar beet in autumn is considered as a better choice to be benefited from autumn and winter precipitation and escaping from water deficit crises. in two areas of aran-o-bidgol, esfahan (ae) and izeh, khuzestan (ik), two independent ex...

this study was conducted to determine the appropriate irrigation interval on the basis of cumulative water evaporation from standard evaporation pan (class a) and to find out the effects of irrigation regimes on growth indices and on qualitative and quantitative yields of sugar beet. the experiment was conducted in 2005 at the lavark agricultural experiment station fields, isfahan university of...

sustainable agriculture for producing food is not possible without optimal use of water resources. because of the limitation of water resources, deficit irrigation would be essential to increase water productivity. in order to evaluate the effects of deficit irrigation on quality and quantity of sugar beet, an experiment was carried out in a farm in miandoab agricultural research station for 2 ...

in most of the sugar beet cultivated areas including kermanshah, iran, late season irrigation is cut- off earlier than usual which causes drought stress in the crop. since root yield still increses in sept. and oct. these areas, withholding irrigation in this period reduce root yield and quality of sugar beet. for this reason, an experimente was conducted during 2004- 2005 based on split plot d...
