In order to investigate the effect of sugarcane compost on consumption of nitrogenous fertilizers in corn fields, a research project was conducted according split plot experiment based on randomized complete block design with three replications along 2015 year. The main plot included different chemical nitrogenous fertilizer (Zero; control, 60 and 120 kg.ha-1 pure nitrogen from urea ...

Field research was conducted in Poland from 2019–2021 to determine the effect of bacteria Azospirillumlipoferum Br17 and Azotobacter chroococcum, as well companion red clover on total protein content yield grain spring barley cultivated a system organic agriculture. Two factors were examined field experiment: I. bacterial formulations: 1—control, 2—nitrogen-fixing (Azospirillumlipoferum Br17, c...

Micropropagation is an important technique for rapid and large-scale multiplication of selected plants. The type and concentration of plant growth regulators and physiological status of the explant have profound effect on the efficacy of plant regeneration. However, success of any micropropagation protocol depends upon the percentage survival and successful establishment of plants from in vitro...

the main objective of this study was to determine the effects of nitrogen fixing bacteria and manure application on the seed yield and yield components in black cumin (nigella sativa l.). the experiment was carried out at the ran research station in firouzkouh in 2012. a 4×4 factorial experiment, arranged in a randomized complete blocks designed with three replications. the treatments consisted...

Studies were carried out on the microflora of phyllosphere and soil rhizosphere of hulled (Chwat variety) and naked (Akt variety) oats. The material taken for study embraced samples of leaves and soil rhizosphere taken from cultivations differing in extent of nitrogen fertilization. The studies involved determination of total number of aerobic heterotrophic bacteria belonging to the genus Pseud...
