objective: a field experiment was conducted at dorud region, iran, during 2013. the aim of this research was study on effect of different biofertilizers and irrigation closed time on some agronomic characteristics of sugar beet (beta vulgaris l.). methods: the experimental design was factorial based on rcbd with three replications. treatments were three irrigation closed time [oct-6 (a1), oct-...
determination of sugar beet standard evapotranspiration by lysimeter method in kabotar-abad, esfahan
for determination of irrigated sugar beet crop evaporation (etc) and water consumption a field experiment was conducted for three years (1991 to 1993) in kabotar-abad agricultural experiment station. the climate was semi-arid according to gossen method with mean annual precipitation of 90 to 110 mm. the soil was esfahan series with a silty clay loam texture. the crop evapotranspiration was mea...
in this thesis protic and aprotic ammonium-based ionic liquids were synthesized and their surface tensions were measured in the range of 298-373k. the protics are alkyl ammonium-based ils with the carboxylate (formate, acetate, propionate) anion and aprotics are quaternary ammonium-based ils with bis(trifluoromethylsulfonyl)imide anion. capillary rise method was used for surface tension measure...
the effect of within-furrow soil compaction and sowing pattern on water use efficiency of sugar beet
this study was conducted in split plot design based on a randomized complete block design in naghadeh region, urmia, iran in 2009-10. two sowing patterns including a1) single row planting with 50 cm between-row spacing, and a2) two rows planting on the hill with 40 cm distance and 50 cm between-row spacing (40×50) were allocated to main plots and four furrow compactions including b1) control, b...
in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...
Drought and low water stress is the most important environmental stress which plant are exposed to in low precipitation regions such as southern and central parts of Iran. Milkweed is one of valuable plant species with numerous industrial (producing high quality fibers) and medicinal benefits which has relatively resistance to drought conditions of southern Iran. The present study aimed to inve...
Introduction: Heat-related illnesses are major causes of morbidity in the world. Workers who are exposed to extreme heat are not be able to activate their compensatory mechanisms and their health will consequently be at risk. Heat stress due to its impact on work performance increases the likelihood of worker disease and injuries and it also affect productivity. During sugar beet harvest, farme...
In Hungary, irrigation determines the success of water-intensive beet cultivation. Taking into account guidelines circular economy, we investigated effect with pre-treated nutrient-rich effluent from an intensive catfish-farm on growth stages sugar and fodder beet. two-year-experiment (2020, 2021), two (‘Helenika’, ‘Grandiosa’) (‘Rózsaszín Béta’, ‘Béta Vöröshenger’) cultivars were grown. additi...
