autumn sugar beet sowing has priority to its spring sowing in terms of economic productivity and water use efficiency. in khorasan razavi and khorasan-e-jonobi provinces, sugar beet is only sown in spring. therefore, it is necessary to evaluate the feasibility of autumn sugar beet sowing in these regions. using geographical information systems is the best and inexpensive way to identify suitabl...
background and objectives: sugar beet (beta vulgaris l.) is the major crop in khorasan province which is mainly grown in spring. however, autumn sowing has a lot of advantages including lower crop water requirement and higher water use efficiency. accordingly, this research was performed to compare the yield of storage organ in spring and autumn-sown sugar beet and determine the most appropriat...
Shortage of irrigation water is the most important limiting factor in sugar beet production, therefore, winter sowing can be a suitable strategy to increase water produvtivity and production of this crop. For this purpose, 11 sugar beet early cultivars were sown in the first half of February and were studied on two different harvest dates (early and late July) at Moghan Agricultural Research St...
the community dynamics of aquatic coleoptera(insecta)in one of the spring-stream habitats of bammo national park in fars province called cheshmeh-ye-ghanbari is studied as a pilot project and model for acquaintance with and furthering the biodiversity studies on fauna of iran. sixteen species-populations out of nineteen of this community were already identified for their taxonomy and for thei...
abstract following innovations in the field of elt, a new topic which has recently attracted a lot of attention is metaphor analysis. although this area of research is still in its infancy in elt, it seems that the idea can shed more light on the puzzle of english language learning and teaching. therefore, the major aim of this study is to analyze language learning and teaching in formal a...
for the first time nakayama introduced qf-ring. in 1967 carl. faith and elbert a. walker showed that r is qf-ring if and only if each injective right r-module is projective if and only if each injective left r-modules is projective. in 1987 s.k.jain and s.r.lopez-permouth proved that every ring homomorphic images of r has the property that each cyclic s-module is essentialy embeddable in dire...
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...
Modification of planting season from spring to autumn in order to use green water, has been introduced as an effective and consistent agronomic strategy with climate change. For this purpose and in order to increase the cultivation of autumn sugar beet as a strategic crops in increasing the self-sufficiency of sugar in the country, it is necessary to implement research programs including determ...
