for determination of economic damage threshold of four wheat (triticum aestivum l.) cultivars in different densities of wild mustard (sinapis arvensis l.), experiments were conducted at agricultural research station gorgan during 2010-2012. the experimental design consisted of four randomized complete blocks in a factorial arrangement. the treatments comprised of factorial combination of wild m...

maize hybrid ksc 706 (k3547/4 × mo17) produced grain yield 11.713 t ha-1, when evaluated in eight locations over two years (2007-8), comparing to ksc 704 with 9.845 t/ha. on farm experiments in 2012, in kermanshah province in two locations, this hybrid produced 13.100 and 13.300 t ha-1 in eslam abad and ravansar as first cropping, respectively, comparing to ksc 704, with 11.300 and 9.700 t ha-1...

this research was carried out to evaluate the effects of some morphophysiological traits on white sugar yield of 10 commercial sugar beet (beta vulgaris l.) varieties. all experiments were conducted in four important sugar beet growing areas in iran, i.e. moghan, khoy, karaj and zarghan in 2006 and 2007. the experiment was arranged as a randomized complete block design with three replications i...

in this study, several artificial neural networks (anns) were developed to estimate seed and grain corn yields in parsabad moghan, iran. the data was collected by a face-to-face interview method from 144 corn farms during 2011. the energy ratios for seed and grain corns were calculated as 0.89 and 2.65, respectively. several multilayer perceptron anns with six neurons in the input layer and one...

in order to evaluate the effects of drought stress and methanol foliar application on some quantitative and qualitative traits of soybean (cv. viliamz), a split plot experiment was conducted based on randomized complete block design at the faculty of moghan research farm in 2011. treatments were three levels of drought stress based on irrigation at depletion of 40, 55 and 70 percent of availabl...

this research in order to identify and introduction of  cotton  suitable cultivar  or cultivars for the double cropping of after wheat and canola harvesting  was carried out in the northern region of ardebil province. in this study, eight  varieties  of    imported cotton germplasm resources in recent years were chosen   and   with the iran's cultivars included  mehr  and varamin  were eva...

the sugar beet plant has a conical-shaped root and at harvest the tap-root breaks which remains in the soil. as a result, a significant amount of root yield and consequently sugar content is lost. furthermore, the field soil remains in the root fissures and is carried with the root to sugar factory. in rhizomania and nematode-infested areas, the soil movement causes the disease wide spread. in ...

in order to study the effect of planting arrangements and water quantities in drip irrigation onyield of maize, an experiment was carried out using a spilt block based on randomizedcomplete block design for three years (2006-09) in moghan. the factorial experiment hadthree planting densities (75000, 85000 and 95000 plants per hectare ) with one- and two-rowscultivation (b1= one row cultivation ...

the main purpose of this research was to analyze the factors affecting on rural people’s participation in the projects of natural resources conservation. the research method of the study was analytical- explanatory research. the statistical population of the study consisted of all the heads of households in rural district of azadlo in moghan township (n= 750). according to krejcie and morgan ta...

the current study was designed to estimate the frequency of igf-i gene 1 polymorphism and investigate if their polymorphisms have association with biometric traits in moghani sheep by pcr-sscp method. for this purpose, a number of 100 sheep were randomly chosen from moghani sheep jafarabad, moghan breeding station that located in ardabil state and blood samples were collected from the left jugu...
