in order to study the effect of vermicompost individually and enriched with chemical fertilizer on soil micronutrient content and micronutrient concentration of lettuce (lactuca sativa l.), athree year experiment was conducted with randomized complete block design in two factors and three replications at the experimental farm of sari agricultural sciences and natural resources university in 200...

field experiment was conducted in 2008 at the research field of agricultural college of shiraz university, shiraz, iran to investigate the effects of urban waste compost (uwc), manure and chemical fertilizer on the initial growth of corn (zea mays). experimental design was split plot factorial with three replications. main plots were assigned to nitrogen (n) fertilizer (0 and 200 kg n ha-1), an...

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 ...

Drought stress is a major environmental stress that restricts plant growth and production in the majority of agricultural fields of the world. The application of different fertilizers, especially biofertilizers and organic fertilizers, might play an important role in the production of medicinal plants in order to improve their resistance to deficit water stress. In order to evaluate the effects...

Two studies were conducted on the use of solid and microbial fertilizers on rice for four cropping seasons (June to October 2010, January to April 2011, June to October 2011 and January to April 2012) at the RM-CARES experimental area, Philippines. One study was conducted in a converted organic area certified organic by the Organic Certification Center of the Philippines (OCCP) and the other on...

Common purslane is a warm season plant which had a lot of medicinal properties. An experiment was conducted as a split plot design arranged  in completely randomized block design with three replications in the research field of Agricultural Sciences and Natural Resources University of Khuzestan during 2015-2016. In this experiment, the main plots consisted of four levels of irrigation intervals...

Semi-arid soils cover a significant area of Earth's land surface and typically contain large amounts of inorganic C. Determining the effects of biochar additions on CO2 emissions from semi-arid soils is therefore essential for evaluating the potential of biochar as a climate change mitigation strategy. Here, we measured the CO2 that evolved from semi-arid calcareous soils amended with biochar a...

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-...
