The effect of fertilizer rate on fruit quality parameters in the black chokeberry (Aronia melanocarpa [Michx] Ell.) cv. `Viking' was studied over three years. A combined N±P±K fertilizer was applied in different rates. Plant height, yield, berry weight, anthocyanin content, content of brown compounds, content of soluble solids, anthocyanin composition and total acidity were recorded for the dif...

The influence of CaCl2 and borax on growth, yield, and quality of tomato was investigated during the years 2009 and 2010. The experiment was laid out with a randomized complete block design. Calcium chloride (0.3% and 0.6%) and borax (0.2% and 0.4%) solutions were applied as foliar sprays either alone or in combination and data were recorded for plant height, branches per plant, flowers per clu...

to study the effect of plant density and planting pattern on iranian ox-tongue, an experiment carried out with two factors: planting pattern (square and rectangular pattern) and plant density (2, 4, 6, 8 plant m-2) in a factorial test performed based on rcbd in 3 replications during 2009-2010 in latmahalleh eshkevarat village in guilan province, iran. characteristics that measured included: dry...

Drought is one of the vitally critical environmental stresses affecting both growth and yield potential in rice. Drought resistance is a complicated quantitative trait that is regulated by numerous small effect loci and hundreds of genes controlling various morphological and physiological responses to drought. For this study, 270 rice landraces and cultivars were analyzed for their drought resi...

chickpea (cicer arietinum) is the third most important pulse crop in the world, grown widely across asia and the middle east. weed is one of the main limiting factors in chickpea (cicer arietinum) production. several characteristics of chickpea (cicer arietinum), such as slow plant emergence, short plant height, and chickpea morphology allow weeds to compete effectively. to investigate the effe...

this experiment was conducted to investigation of some agronomical traits in different castor bean genotypes at west azarbaijan, in agricultural research station of urmia, as completely randomized block design with three replications, during 2007-2008. result showed that the effect of different genotypes were significant on all characteristics. the highest and lowest number of grain per plant o...

pistacia atlantica is the most important tree species for the economy of many rural areas in west of iran, but no effort has been made for the genetic improvement of this species. the aim of this investigation was to study the genetic variation and inheritance of early growth traits in p. atlantica. for this purpose, three wild pistachio populations comprising 60 randomly selected adult trees f...
