response surface models predict crop yield based on crop density and this is an important tool for evaluation competition at different density and hence selection of optimum density based on yield. in order to study intra and inter specific competition in intercropping bean (phaseolus vulgaris) and sesame (sesamum indicum), an experiment was conducted at the agricultural research station, ferdo...

in order to study the effects of different amounts of nitrogen and plant density on yield, yield components and seed oil percentage of pumpkin (cucurbita pepo l.) an experiment was conducted as split plot based on randomized complete block design with two factors and three replications at agricultural research field station of ferdowsi university of mashhad, iran, during growing season 2010-201...

The investigation was conducted on wet and dry seasons of Ethiopia during the year 2012/2013 at Wondo Genet Agricultural Research Center Nursery site. Four levels of cutting size and three levels of cutting positions were arranged in randomized complete block design with three replications. Data on seedling height, branch number/seedling, root number/seedling, root weigh/seedling, root length/s...

in line with an investigation regarding to evaluation of the compatibility of the asian pear cultivars with iran climatic conditions – currently being carried out at the horticultural department of tarbiyat modares university (tmu) – the present preliminary study was performed in two regions in isfahan. asian pear (pyrus serotina rehd.) cultivars (grafted on european pear seedling rootstocks) w...

abstract cumin is one the most important medicinal plant in iran. a field experiment was conducted in order to evaluate the effect of compost (30t/ha), vermicompost (10t/ha), cow manure (30t/ha) and sheep manure (20t/ha) and control (no fertilizer) on yield and yield components of cumin. the experiment was performed in the research farm of faculty of agriculture, ferdowsi university of mashhad ...

drought, specially in reproductive stage is one of the major constraints, limiting the productivity of crops, including chickpea (cicer arietinum l.). to study the effects of drought during pod set and seed filling stages (terminal drought) on phenology, growth and seed yield of 5 kabuli chickpea genotypes of: arman, jam, hasham, flip93-93 (azad) and ilc482, an experiment was conducted during t...

a field experiment was conducted to study the spatial relationships between weed seed bank and population and their distribution models in sugar beet crop (beta vulgaris) in 2009 at motahari  agricultural research station of karaj. sampling from seed bank before sugar beet drilling and weed population in three stages during the growing season were done using square (50*50 cm) and rectangle (25*...
