this study was carried out to evaluate the antifungal efficacy of garlic essential oil (allium sativum l.) and two fungicides including metalaxyl- mancozeb and mancozeb against phytophthora melonis, p. drechsleri and p. capsici the causal agent of damping- off on pepper, melon and cucumber, in vitro and greenhouse conditions. fungal radial growth for each concentration of garlic oil on phytopht...

to estimate combining ability and the model of gene action for some quantitative characters, 5 different rice genotypes were used for producing a half diallel hybrids. to consider 7 quantitative traits, hybrids and their corresponding parents were evaluated based on a randomized complete block design with three replications at the rice research station of amol, iran in 2007. mean squares regard...

oil uptake is one of the most important aspects about product quality during frying. the purpose of this study was to investigate the effect of temperature on oil content of final product and its perception using empirical models. therefore, potato stripes in specified size, after blanching were fried using a fryer equipped with thermo controller at 145, 160 and 175 º c for 60, 120, 180 and 240...

the extensive use of pesticides in agriculture is compromising soil and water quality. one major concern is protecting water resources from contamination. the main objective of this research was measuring 2,4- d in a silty clay soil and simulating temporal transportation of this herbicide in soil using a leachp model, in a corn root zone field. 2,4- d was applied at 3.5 kg a.i./ha, followed by ...

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...

in order to evaluate the effects of organic fertilizer complements application (aminol forte, fosnutren and kadostim) on grain yield, milling properties and nitrogen use efficiency of two rice (oryza sativa l.) cultivars, a field experiment in factorial layout and a randomized complete block design with 10 treatments and 3 replications was conducted at rice research institute of iran in 2009. t...

drought as a climatic phenomenon affected many different environmental issues and generally is associated with the decreasing in average precipitation. evaluation and monitoring of the drought is a fundamental step in proper programming of water resources management. regarding the recent conditions water scarcity in the urmia lake basin, assessment of the drought index in this region is inevita...

the moe and mor are controlled by production variables of particleboard process. now, the basic question is which of the particleboard variables is effective on bending strength property? 13 variables of internal scientific resources were measured with 100 repeats. the study steps include the following; liner regression or stepwise, genetic algorithm, and artificial neural network. the number o...

a field experiment was conducted in research farm of isfahan university of technology, isfahan, iran in 2011 . various weeding periods were investigated on growth and yield of potato under drip tape and furrow irrigation systems. a split plot arrangement was used in a randomized complete block design with three replications. irrigation treatments were included in main plots and periods of weed ...

to evaluate of quantitative and qualitative yield of two basil (ocimum basilicum l.) medicinal plants as affected by planting pattern and plant density, an experiment carried out in factorial arrangement basis on randomized complete block design with three replications. two varieties (green and purple) of basil, two planting patterns (single and double row) and four plant densities (40, 60, 80 ...
