In order to evaluate the effects of inoculants and chemical fertilizer on quantitative and qualitative yield, a bread wheat cultivar treated with Azotobacter, arbuscular mycorrhiza fungi (AMF) and nitrogen sources by using split plot on the basis of randomized complete block design with three replications in Fars Agricultural Research Station during 2007-2008. Main plots consisted of nitrogen f...

introduction: drought stress is one of the main problems in agricultural productions in arid and semiarid regions such as iran. lack of water influences on most of plant physiological processes such as photosynthes, cellular development and uptake and transmission of nutrients in plants. some approaches such as selection of resistance cultivars to drought stress, and selection of dripped irriga...

The area planted with avocado crops in Colombia has been growing rapidly recent years, especially for export varieties such as Hass. increase coincided increased phytosanitary problems, where pathogens fungi of the genus Verticillium spp. are becoming economic importance. objective this study was to evaluate different control strategies wilt disease caused by spp., under vitro, net house, and f...

Fungi profoundly affect nearly all terrestrial ecological processes and events; accurate information on the fungal component is required to adequately understand how ecosystems function (Trappe and Luoma 1992). When fungal mycelia form particular associations with a host plant’s fine roots, a symbiotic organ forms, called a mycorrhiza. Through this structure the plant provides carbohydrates to ...

Berries such as strawberries are recognized a significant constituent of healthy human diets owing to their bioactive secondary metabolites. To improve crop sustainability, yield and berry quality, alternative production systems should be proposed organic farming the use biostimulants. Thus, we have compared within complete randomized block design seven biostimulant treatments: 1-control, 2-sea...

to study the effect of chemical and biological fertilizers on growth and essential oil content of lavender (lavandula angustifolia mill.), the present work was conducted in 2012-2013 at the experimental field of alborz research station of the research institute of forests and rangelands, karaj, iran. the experiment was conducted in factorial in the form of a randomized complete block design wit...
