this research set out to evaluate the effect of combined biological and chemical nitrogen fertilizers on some corn hybrids. to this end an experiment was conducted as split plot on the basis of randomized complete block design with four replications. main plots were included: use of chemical and biological fertilizers in four levels: 100% chemical fertilizer, 75% chemical fertilizer + 100% bio-...

Nitrous oxide (N2O) emissions from a maize field in the North China Plain (Wangdu County, Hebei Province, China) were investigated using static chambers during two consecutive maize growing seasons in the 2008 and 2009. The N2O pulse emissions occurred with duration of about 10 days after basal and additional fertilizer applications in the both years. The average N20 fluxes from the CK (control...

introduction savory (satureja hortensis l.) is an annual herbaceous plant that belongs to the lamiaceae family. nowadays, the use of biofertilizers is increased in agriculture and their role in increasing the crops production has been demonstrated in many research works (vessey, 2003; chen, 2006; mahfouz & sharaf- eldin, 2007). one of the most important visions is sustainable production of enou...

Abstract Nutmeg is important for national and community revenue mainly in Maluku Province where nutmeg seedlings are grown low-fertility soil without fertilizer. A greenhouse experiment was performed to evaluate the response of following application two different biofertilizer concortia. The experimental design completely randomized block design, which tested combination treatments rates method...

in order to comparison the foliar application of biological, biostimulator and chemical fertilizers on growth characteristics and yield of saffron, a factorial experiment was conducted in a completely randomized block design with four replication in 3- year field of saffron in dargaz, khorasan razavi province from 2010 to 2011. the first factor had 5 levels included biostimulator fertilizer bio...

thyme (thymus vulgaris l.) is perennial aromatic shrub belonging to the mint family which has anti-spasmodic, antiseptic, carminative, anti-cough, sputum and antioxidant properties. in order to study the effects of drought stress and bio-fertilizer on plant growth, essential oil yield and constituents of thyme plant, an experiment was conducted in a split plot based on randomized complete block...

Cassava root rot causes significant production losses. Difficulties of management, along with the lack chemical fungicides officially registered by Ministry Agriculture, Livestock and Supply (MAPA), require alternative control methods. This study investigated in vitro antagonistic activity Trichoderma harzianum as well a biological fertilizer MICROGEO® on Fusarium solani. The phytophatogenic st...

The study investigates biochar from agriculture waste and flyash coal power station as possible carrier materials for two plant growth-promoting (PGP) bacterial strains Burkholderia sp. L2 Bacillus A30 enhanced eggplant growth yield. Biochar-based biofertilizers with/without showed higher viability up to 270 days of storage period. maximum percentage seed germination was observed in L2-based + ...

in order to evaluate the effects of organic, biological and chemical fertilizers on yield and yield components of milk thistle (silybum marianum l.), an experiment was conducted at the research station of ferdowsi university of mashhad based on complete randomized block design with three replications and six treatments during year 2007. treatments included inoculated seeds with azotobacter, com...
