abstract in order to study the effects on salinity and silicon application on yield and yield components of purslane (portulaca oleracea l.), an experiment was conducted in a completely randomized desgin with three replications and two factors consisted of four different levels of salinity using nacl (0, 7, 14, 21ds/m) and two levels of silicon (application of one mmol sodium silicate and not a...

a factorial experiment based on complete block design was conducted to study the interactive effects of sulfur fertilizer and thiobacillus bacteria on corn growth and root colonization with two species of mycorrhiza fungi. treatments were five levels of sulfur (s0: 0, s1: 50, s2: 100, s3: 150 and s4: 200 mg.kg-1 of dry soil), thiobacillus in two levels [no application (t0) and application of ba...

background: about 90% of the world�s contraceptive users are women. this gender-based usage has occurred due to the emphasis of family planning programs and contraception research. condom, vasectomy and withdrawal are the only male contraception devices available with less assurance for men. for new male contraceptive to have an impact, they must be acceptable to both men and women, as well as ...

In order to study of hydropriming and halopriming on germination and early growth stage of wheat (Triticum aestivum L.) an experiment was carried out in laboratory of the Department of AgroNomy and Plant breeding, Shahrood University of Technology. Seed treatments consisted of T1: control (untreated seeds), T2: soaking in distilled water for 18 h (hydropriming). T3: soaking in -1.2 MPa solution...

To study the effects of halopriming and hydropriming in overcoming salt and drought stress in corn (Zea mays L.),two experiments were separately conducted at Shahrood University of Technology. Seed treatments consisted ofcontrol (untreated seeds), soaking in distilled water for 32 h (hydropriming), and soaking in 50 mmol solution ofCaCl2 for 16 h (halopriming). Germination and early seedling gr...

 In order to study on effect of magnetic field on germination characteristics and early growth of marigold (Calendula officinalis L.) seeds an experiment was carried out in laboratory conditions in Arak University of Iran. Seeds were magnetically exposed to magnetic field strengths, 100 or 200 mT for different periods of time; D1 (control), D2 (1 h), D3 (6 h), D4 (12h), D5 (24 h) and D6 (contin...

Adult female crabs (Potamonpersicum; n=65) were collected from the Jajrood River in the east of Tehran, Iran. Both eyestalks were removed in crabs that weighed 27.6 ± 2.1 g. Changes in the levels of glucose and protein titers in the hemolymph, the number of hemocytes, gonadal and hepatic indices, body weight and carapace length were determined. The level of glucose in the hemolymph was signific...

The aim of this study was to assess the effects of strip cropping and different weed control methods on the yield and yield structure of dent maize, narrow-leafed lupin and spring oat. A split-plot design with four replications was conducted in 2008-2010. The following factors were analysed in the experiment: I. Cultivation method – sole cropping and strip cropping; II. Weed control method ...
