In this research, the effect of organic fertilizers was studied on the growth performance of carps fry. This experiment was conducted in a completely randomized design with seven treatments and three replications in 300 liters of tanks within 3 months. 60 pieces of fish fry with an average weight of 0.6 ± 0.05 g were randomly storage in each tank per 0.5: 1.5: 2: 6 (respectively, 5%, 15%, 20% a...

This study was aimed to evaluate the possibility of using enriched vermicompost with salt-tolerant strains of Streptomyces as a bio-fertilizer in growth and nutrition of cucumber under salinty stress. For this purpose, a pot experiment was set up in a completely randomized factorial design with three replications. Treatments included different salinity levels (0, 30, 60 and 90 mM sodium chlorid...

In order to increase the available Phosphorous (P), chemical fertilizers are applied; however, P chemical fertilizers are transformed into low available forms over time. Organic amendments could be effective in improving the efficiency of P fertilizers. The aim of this study was to investigate the effect of P fertilizers and vermicopost on the availability and fractions of P and maize (Zea Mays...

in this study, the effects of oleothermal modification on physical and mechanical peroperties of fir wood (abeis sp.) blocks were examined. at first, some blocks of fir wood with 5 × 20 × 120 cm dimensions were prepared. the blocks were treated in soybean oil. the effects of 3 factors such as treatments temperature (180and 200 °c), holding time (12 and 15 h) and initial moisture content of wood...

this exploratory study aimed to investigate a possible relationship between learners’ beliefs about language learning and one of their personality traits; that is,locus of control (loc). both variables, beliefs and locus of control, are assumed to influence the language learning process. the internal control index (ici) and the beliefs about language learning inventory (balli) were administered...
