In Europe, the framework for sugar beet (Beta vulgaris L.) production was subject to considerable changes and for the future it is expected that sugar beet cultivation might concentrate around the sugar factories for economic reasons. Based on data from a national sugar beet farmers' survey and multi-year crop rotation trials, the effects of cropping interval (number of years in between two sub...
The paper reflects the results of effectiveness use various doses mineral fertilizers in a long stationary experiment on spring soft wheat for nine rotations six-field crop rotation (27 years cultivation) conditions steppe zone Volga region. systematic medium and high nitrogen-phosphorus contributed to obtaining highest yield increases control throughout entire research period. average level co...
Given the climatic changes and threats to food security in recent years, they have have become a major issue in agricultural climatology. The present study aimed to investigate the status of agricultural climate suitable for the cultivation of rice in the light of the influential climatic conditions in the past. Given the effect of temperature and the amount of precipitations on rice growth and...
in recent years, there has been a growing interest among researchers to investigate the relationship betweenteacher self-efficacy and classroom behavior management, especially students misbehavior. therefore, this study aimed to comparatively investigate english and arabic teachers’ use of different behavior managementstrategies, their self-efficacy, and their success in an iranian context. th...

The effect of substrate concentration, pH and cultivation time on the production of endoxylanase from Aspergillus awamori ZH-26 were optimized by statistical analysis using response surface methodology (RSM). Endoxylanase production was optimized by central composite rotary design. Statistical analysis of the results showed that the linear and quadratic terms of these three variables had signif...

Salt stress is one of the major constraints for wheat cultivation inIranand leads to a considerable loss in crop yield each year. In high salinity soils, the reduced osmotic potential of soil solutes may cause physiological drought. In this study the salt tolerance of different drought-tolerant bread wheat genotypes were studied by examining various agronomic and physiological traits, inclu...
In order to identify the plant-parasitic nematodes of important cereals (wheat, barley, and corn) in Isfahan Province, 120 soil and root samples were collected from the rhizosphere of these crops in various locations in the region during 1999 and 2000. Nematodes were extracted from soil by sieving and centrifugal sugar-flotation method. The specimens were killed and fixed in FGA (formaldehyde, ...
