in order to investigate the influence of bio- and chemical fertilizers on growth parameters and essential oil of fennel (foeniculum vulgare miller.), an experiment based on randomized complete blocks design with five treatments and three replications was carried out. arbuscular mycorrhizal fungi (strain sebacina vermifera) and phosphate dissolving bacteria (genera peseudomonas) were applied as ...

Bio-fertilizers are naturally occurring soil bacteria that aggressively colonize plant roots and benefit plants by providing growth promotion. This investigation was aimed at determining the effect of Nitroxin bio-fertilizer application on growth, inoculation and yield production of corn hybrids. An experiment was conducted as split plot on the basis of randomized complete block design with fou...

The present work was conducted to find out the effect of biofertilizer formulated with four species of bacteria (two species of Azotobacter and two species of Lysobacter) and zinc sulphate. Field experiments with mustard plant were conducted to study the effectiveness of soil application of zinc sulphate and biofertilizer at 0, 10, 20, 30, 40, 50 days after sowing. Plant height and condition of...

to study the effect of drought stress during using organic and chemical fertilizers on morphological, agronomic traits and the essential oil of coriander, a field experiment was conducted as split plot based on randomized complete block design in three replications at agricultural research station, college of agriculture, university of torbat heydarieh, iran during growing season of 2010-2011. ...

The growth and quality of medicinal plants are greatly affected by environmental stress, with over half the world’s agricultural land facing water shortages. This research was conducted two seasons in 2018 2019 aimed to investigate influence varying irrigation intervals partial replacement mineral fertilizers biofertilizer (yeast) on growth, yield, essential oil content lemongrass. study also l...

Land-use conversion from woodlands to tea fields in subtropical areas of central China leads to increased nitrous oxide (N2O) emissions, partly due to increased nitrogen fertilizer use. A field investigation of N2O using a static closed chamber-gas chromatography revealed that the average N2O fluxes in tea fields with 225 kg N ha(-1) yr(-1) fertilizer application were 9.4 ± 6.2 times higher tha...

A field experiment was conducted to study the effect of a Pseudomonas fluorescens-based biofertilizer on sweet potato (Ipomoea batatas (L) Lam) yield. The application by immersion cuttings before sowing for 0, 5, 10 and 15 minutes with combination doses 50 100% NPK mineral fertilizer in randomized block design three replications (12 treatments-combinations). During harvest (130 days after plant...

In order to investigate the possibility of using organic fertilizers in tobacco floating nursery, an experiment was conducted at tobacco research institute of Urmia in 2010. The experiment was done as factorial trail based on randomized complete block design (CRBD) with four replications. The levels of first factor were disinfected poultry manure, disinfected pigeon manure, a complete fertilize...
