salt stress negatively impacts crops yield throughout the world. nine varieties of potato (solanum tuberosum l.) were screened for salt stress tolerance by measuring in-vitro growth of the aerial plant parts, as well as roots. salt stress was evaluated by adding 25, 50, 75, 100, 125, 150 and 200 mm of nacl to murashige- skoog (ms) medium and compared to ms medium without nacl. plant length and ...

nitrate and ammonium ions are the two major forms of nitrogen that taken up by plants, but they differ in their effects on growth and chemical composition of biochemical levels. in this research we examined the effect of nitrogen sources on growth and senescence of rice leaves in biochemical levels. our results showed that amounts of fresh and dry weights, total chlorophyll, rate of hill,s reac...

in this research, the effect of using vermicompost on growth rate, fertility and characteristics oftomatoes has been studied. four vermicompost: soil mixture were supplied with ratios of 1:1, 1:2, 1:3, and 1:4 and also four different beds were provided. total of 24 small globe tomato plants were tested and in each bed combination, six tomato plants were embedded. rate of growth and yielding of ...

It has been characterised hypoglycemic, hypotensive, antioxidant antibiotic properties. This study was conducted to determine the impact of plant growth-promoting potential bacterial strain Bacillus subtilis L2 on growth physiological prop...

abstract plant- growth promoting rhizobacteria enhance plant growth and yield directly and or indirectly. a factorial experiment was conducted in greenhouse to determine the efficacy of four strains of fluorescent pseudomonas on wheat yield and yield component under saline conditions. the experiment was carried out with the following treatments (non –inoculation control and inoculation with p.f...

application of most antibiotic growth promoters as feed additives has been banned in a lot of countries due to cross-resistance against pathogens and residues in tissues. therefore, scientists are searching for alternatives to antibiotics nowadays. medicinal plant extracts are one of the alternatives that have anti-microbial and growth promoting effect on poultry. in this paper, the benefits of...
