Tomato (Lycpoersicum esculemtum) belongs to the Solanaceae potato family and is an important crop plant. It is relatively resistant to salinity, but in the saline environment growth and production of the plant significantly reduces. On the other hand, the presence of mycorrhiza fungus can improve the adverse effects of salinity. A factorial experiment in a completely randomized design with thre...

.in order to investigate the effects of plant growth promoting rhizobacteria and nitrogen fertilizer on morphological traits of german chamomile (matricaria chamomilla l.), a field experiment was carried out as factorial based on randomized complete block design with three replications in research farm of the faculty of agriculture, university of tabriz, iran, during 2007-2008. factors were ino...

aimed at reducing the consumption of chemical fertilizers on crop production and according to important role of micro-nutrients such as iron, on increase performance of these products, nanocomposites effect of iron on yield and yield components of wax bean genotypes inoculated with rhizobium bacteria during experimental factorial randomized complete block design with three replications was cond...

Downy mildew, caused by Peronospora parasitica Pers. ex Fr., is an important disease of canola that has implications during early seedling establishment. The fungus invades young seedlings and severe infection results in premature defoliation. In worst cases, the systemic infection may even kill the seedlings. Current commercial varieties of canola are very susceptible to downy mildew. Therefor...

introduction: sulfur is the key element for higher crops and plays an important role in the formation of proteins, vitamins, and enzymes. it is a constituent of amino acids such as cysteine and methionine, which act for the synthesis of other compounds containing reduced sulfur, such as chlorophyll and utilization of phosphorus and otheressential nutrients.deficiency of this nutrient in soil is...

Formulating new integrated plant nutrient management (IPNM) strategies in order to sustain crop production and protect the environment has become an important issue present agricultural system. Therefore, a field study was carried out two seasons 2016 2017 formulate best IPNM for improving growth, yield, quality of maize grown arid agro-ecosystem. The comprised full-dose NPK (T1); composted was...

to study the effects of biofertilizers in their different levels of nitrogen (n) and phosphorus (p) on yield related parameters of barley (sahra cultivar), a split plot experiment based upon a randomized complete block design of three replications was conducted. main plots consisted of: nitrogen at three levels (0, 50 and 100 kg n ha-1 as urea), while sub plots were: phosphorus at two levels (0...

Raw seed sprouts have caused numerous outbreaks of enteric infections. Presoaking seeds in a 20,000 mg/liter (ppm) calcium hypochlorite solution before sprouting is recommended to reduce bacterial contamination and infection risk. In 1999, the authors investigated an outbreak of Salmonella serotype Typhimurium infections in Colorado. In a case-control study, they matched 20 cases with 58 contro...

In order to evaluate the Effects of dual inoculation of Azotobacter and Mycorrhiza with Nitrogen and Phosphorus levels on yield and yield components of spring safflower, this study was carried out in field of Farahan university in Markazi province in 2007. A factorial in a randomized complete block design with three replications was used inoculation of Azotobacter (with inoculation and without ...
