this experiment was conducted to study the effects of single and combined application of organic, biological and chemical fertilizers on qualitative and quantitative characteristics of vegetative part of coriander, (coriandrum sativum l.). the experiment was carried out as split plot in time based on complete randomized block design with three replications and 12 treatments at research station,...

today, the production of healthy and high quality seedlings is the main factors of success in growing vegetables such as tomato. hence, in order to investigate the effect of different levels of vermicompost and nitrogen on the growth parameters of tomato seedlings (lycopersicon esculentum mill. cv. rio grande), a factorial experiment was conducted in a randomized complete design with three repl...

in order  to study the effect of drought stress on some growth indices of oil sunflower cultivars, a study was conducted in isfahan. the experiment was conducted as split plots in a randomized complete blocks design with three replications in isfahan (51° 48' e, 32° 40' n).main plots were drought stress in four levels (80, 100, 120, and 140 mm evaporation from evaporation pan class a and cultiv...

In order to study the effect of silver nanoparticles and magnetic field on Raphanus sativus. experiments were carried out with four treatments in 10 days. Treatments were including (CON) control, (MF) magnetic field with B=1.8 mT for 1h per day in 10 days, (SNPs) silver nanoparticles (50 ppm), (MF+SNPs) magnetic field plus silver nanoparticles. Results showed that silver nanoparticles (SNPs) ha...

Three genes from the T(R) region of pTi15955 were introduced into tobacco (Nicotiana tabacum L.) to direct the synthesis of the mannityl opines from hexose sugars and glutamine or glutamate. Opines were present in all tissue types tested and accumulated to levels of 100 to 150 micrograms per milligram dry weight in root, stem, and leaf tissues. Opine-producing plants appeared normal with respec...

in order to evaluation of plant densities and row spacing effects on growth and yield of wheat, an experiment was conducted by using four plant densities (125, 250, 375 and 500 plants per m2),two row spacing (12.5 and 25 cm), in a randomized complete block design with three replicates in anbare-ololum reign in rainfed and saline conditions during 2008-2009. results showed that leaf area index (...
