Tobacco is a salt-sensitive glycophyte crop species. In this work effect of silicone (Si) supplementation (1 mM as Na2SiO3) was studied in Nicotiana rustica L. cv. Basmas grown hydroponically in growth chamber under control, low (25 mM) and high (75 mM) NaCl concentration for two weeks. Dry matter production of leaves was depressed by salinity level as low as 25 mM and higher salt concentration...

The various dilution levels of treated tannery effluent (T.E.) (10, 25, 50 and 100%) and Cr6+ (0.5, 2.0, 5.0 and 10 ppm) were used in experiment to know their effect on seed germination, seedling growth, pigments and enzymes content in Black gram (Phaseolus mungo Roxb.). Chromium is known as the main toxic component of tannery effluent so its various concentration were given to know their effec...

this study was aimed to assess of priming effects on soluble proteins and antioxidant enzymes of as a nigella sativa medicinal plant under different levels of salinity and drought. two greenhouse factorial experiments with three replicated randomized complete block design were conducted.treatments included five levels of priming (potassium nitrate 1% and salicylic acid 0.2 mm in 6 hours, potass...

ABSTRACT Sweet potatoes are an important staple food for human consumption. This study evaluated sweet potato yield in response to potassium fertilization using different sources and splitting. It was conducted at the Universidade Federal da Paraíba, Areia-PB. A complete randomized block experimental design used a 7 × 2 factorial arrangement. The split into seven treatments (100% after planting...

in the present study, effects of iron excess treatments (0, 250, 500 mg l-1) were evaluated in four rice varieties including shafagh, khazar, hashemi and sadri in pot condition. afterward, effects of iron excess (10 and 250 mg l-1) were further investigated in the most resistant variety (shafagh) in sand culture with yoshida nutrient solution. this experiment was arranged as factorial in rcbd w...

Investigating the effect of various sources sulfurous compounds along with inoculation Thiobacillus bacteria on corn plants under stress conditions lead and zinc metals, an experiment executed at zanjan uni researching green house. The treatments include elemental sulfur (0.75, 1.25 2 g/kg soil), (1, 3 soil) potassium sulfate (0.5, 1 1.5 soil ). results showed that traits were significant in al...

Subterranean clover inoculated or not with the arbuscular mycorrhizal (AM) fungus Glomus intraradices was grown on soil containing six levels of 238U in the range 0-87 mg kg(-1). Increasing U concentration in soil enhanced the U concentration in roots and shoots of both mycorrhizal and nonmycorrhizal plants but had no significant effects on plant dry matter production or root AM colonization. M...
