in order to evaluate the effect of humic acid and zn on the grape yield and mineral concentration, a factorial experiment was conducted based on a randomized complete block design with three replications. the study was done on 20 years old grapevines in the farsan region from chaharmahal and bakhtiari province in 2013-2014. each of the factors, humic acid and zinc sulfate, were applied in three...

this study was conducted to determine the effects of the combined use of rain shelters (rs) and deficit irrigation (di) on tomato yield and quality characteristics. two experiments with different treatments were conducted in the southern china during the growing season in 2011 and 2012. the crops were irrigated to field capacity once average soil water content at the 0-60 cm layer in the treatm...

An increasing world population and the competitive nature of the stone fruit market, particularly nectarines [(Prunus persica var. nectarine)], demand the selection of fruit with high quality attributes, flavor, and a wide range of maturity. Information on this subject is limited at the present time. In search of superior nectarines, a trial was conducted to study growing degree days (GDD), ful...

fruit productivity and quality of eight years peach and nectarine cultivars (rich lady, ryan sun, ruby diamond and venus) grafted onto cadaman-avimag, viking, atlas, gxn 15, gf 677, mrs 2/5 and nemaguard (control) rootstocks were evaluated. a split plot experimental design was used, with each rootstock/scion combination as an experimental unit. total yield, fruit size distribution, number of fr...

the following study was conducted at the research station of horticultural sciences (university of tehran, karaj) to investigate the effect of different irrigation levels and fruit site on the stalk upon the traits of: sink-source relationship, yield, and fruit quality in two iranian melon cultivars. the statistical design was a split split-plot of  three replications. treatments consisted of a...

this investigation was carried out in a commercial orchard in ashtian city, markazi province. the effect of n-phenyl-phthalamic acid and nutrition on fruit quantity and quality of plum cv. maragheh was studied with the aim of increasing yield. the n-phenyl-phthalamic treatments (concentrations, 0, 500 and 1000 mg/l) were performed at full bloom (80 % flowering) on 29 march. also, nutrition was ...

peach genotypes showing notable fruit and tree traits were selected in ardabil and east azarbaijan provinces of iran. genotypes were grafted on seed rootstocks and cultured with 4×4 m spacing. traits such as tree growth habit, flowering, maturity, morphological and qualitative fruit characteristics were described in 15 peach genotypes using ibpgr peach descriptors during the 2005-2007 seasons. ...

The low fruit set is one of the main factors leading to poor yield of pear orchards in Brazil. The exogenous application of thidiazuron (TDZ) and aminoethoxyvinilglycine (AVG) has shown promising results in some pear cultivars and other temperate fruit trees. The objective of this study was to evaluate the effect of TDZ and AVG on fruit set, yield, and fruit quality of 'Hosui' and 'Packham's Tr...
