In order to study the effect of drought stress on growth of new hybrids of maize an experiment was carried out at Safi Abad Agricultural Research Center, Dezful, Iran. The experiment was arranged as a split plot in a randomized complete block design with three replications. Treatments consisted of four levels of drought stress (irrigation after 75(±5) (Control), 95(±5) (mild stress), 115(±5) (m...
mungbean (vigna radiata (l.) wilczek) or green gram as a dryland grain legume is exposed to varied timings and severity of drought stress, resulting in variability in photoassimilate production. in order to evaluate some physiological responses in one mungbean cultivar to timing and severity of drought stress, a 3-replicate rcbd (randomized complete block design) field experiment was carried ou...
emergence of crops is affected by environmental factors such as soil water, salinity and sowing and seed quality. the present study was conducted to evaluate the effect of seed aging (seed quality) on emergence of wheat under optimum (control) and stressful conditions including salinity (2 levels), drought (2 levels) and deep sowing depth (physical stress). seeds (cv. ‘zagros’) were kept at a h...
This research was carried out to evaluate the effect of drought stress on grain yield and qualitative traits in some Iranian landraces of confectionary sunflower. Fifty six confectionary sunflower landraces were evaluated using three different water treatment conditions with three separate rectangular 7 × 8 lattice design with two replications. Irrigation treatments were as follows optimum irri...
Salinity is one of the main obstacles to the successful production of agricultural products. Hormonal compounds such as salicylic acid (SA) as plant growth regulators can have different physiological and biochemical effects in plants under salt stress. In present research, the effects of different concentrations of sodium chloride (2, 6 and 10 dS/m) and foliar application of SA (0, 0.25 and ...
Background and Objective: Rural wastewater management is recognized as one of the pillars of sustainable development. Therefore, the purpose of this study was to assess needs and prioritization of establishment of rural wastewater management facilities in order to supply a safe and alternative water source in the provinces of Iran experiencing severe water stress. Materials and Methods: This i...
attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
Water resources are limited. Thus, one of the ways to prevent the decline of maize yield under water shortage conditions is the use of growth regulators. In this study, the effects of proline (150 mg/L) and salicylic acid (0.5 mmol) on the yield and water use efficiency of maize were investigated under three irrigation regimes, including complete irrigation (control), 75% of complete irrigatio...
in order to study the effects of drought stress and organic fertilizers (compost and vermicompost) on some physiological and biochemical characteristics of borage, an experiment with complete randomized block design in split plot arrangement with three replications was conducted in zabol university, zabol, iran. the treatments included 3 levels of stress as a witness or 100% of field capacity, ...
background epilepsy is a chronic disease that affects the behavior and cognitive performance of children. in many cases, the emotional impacts of epilepsy on the family are neglected. besides the emotional distress, recurrent seizures may lead to irreversible effects on family members, especially parents. objectives this study aimed to evaluate the prevalence of anxiety, stress and depressive d...
