in order to evaluate the effect of foliar application of salicylic acid on the qualitative characters of strawberry fruit, a factorial experiment (treatment+ the time of harvesting) based on completely randomized design with 3 replications was conducted in a greenhouse and the laboratories of department of horticultural science of university college of agriculture and natural resources, univers...

drought tolerances of 55 indigenous strains of pseudomonas fluorescens were evaluated. to assess the tolerance rate of the strains to various levels of water deficit, their growth rate in nb medium containing concentrations of 40.587, 438.838 and 548.838 g of polyethylene glycol 6000 per liter of medium were utilized. water potentials of aforesaid levels were estimated as 0, - 10, - 20 and -30 ...

to identify the high yielding lines with optimal characteristics, 40 recombinant inbred lines derived from a cross between ‘norstar’ (winter wheat) and ‘zagros’ (spring wheat) cultivars were examined using a randomized complete block design with three replications in 2014 at the research station of faculty of agriculture, university of tabriz, iran. the measured characters consisted of peduncle...

the aim of this study was to investigate the barrier properties of cellulose nanocrystals-pvananocomposites. nanocomposite films with different filler loading levels (3, 6, 9 and 12% by wt) weredeveloped by solvent casting method. the effect of cellulose nanocrystals on the barrier properties ofthe nanocomposites was studied. to this end, moisture absorption, water vapor permeability (wvp),oxyg...

water is the most important factor for agriculture development in iran. accordingly the optimal consumptione of water is very important. using pressurized irrigation system is one of the methods to improve agricultural water management. the objecttives of this research were to compare two irrigation methods of furrow and trickle irrigation systems impacts on quantity and quality characters of s...

in the water-limited areas, the great challenge of the agricultural sector is more production from less water that it can be achieved by increasing water productivity. a field study was conducted to compare various cultivars of wheat to water using line source sprinkler irrigation at gorgan research station in 2005-2006. the effect of variable water supply on yield and wue of six wheat cultivar...

decreasing water loss and increasing the irrigation times are basic methods to develop agriculture, success in natural recourse projects, minimize the stress to planted bushes in natural fields and increase the productivity of soil and water sources. the use of super absorbent is one of these strategies to achieve these goals. the main purpose of this research was to study the effect of super a...
