growing demand for wheat grain with optimal technological parameters results in looking for the possibilities of accurately meeting the plant needs. environmental conditions in the surroundings of germinating grains can be improved by application of humic preparations. qualitative features of grain can be also changed by foliar application of potassium, which is the activator of enzymes catalys...

The objectives of this study were to determine whether foliar application of a chlorophyll precursor, 5-aminolevulinic acid (ALA), could mitigate salinity stress damages in perennial grass species by regulating photosynthetic activities, ion content, antioxidant metabolism, or metabolite accumulation. A salinity-sensitive perennial grass species, creeping bentgrass (Agrostis stolonifera), was i...

To study the impact of iron nanoparticles foliar application on mitigating the effects of drought stress on yield, yield components and oil percentage of Goldasht spring safflower cultivar, an experiment was carried out in 2012 in the Agricultural Research Farm Station of Islamic Azad University, Roudehen branch as split plot in a completely randomized blocks design with three replications. In ...

due to extent of zinc (zn) deficiency in soils of iran and its deficiency in human diet, this study investigated the effect of zn sulfate foliar applications (non-foliar application, 0.5 g/l at stem elongation stage, 0.5 g/l at stem elongation and grain filling stages, 0.5 g/l at stem elongation and 2 g/l at grain filling stages) on yield and its components (farm sector) and influence of grain ...

the responses of isabgol (plantago ovata forsk.) to micronutrient foliar application under low irrigation condition were investigated. the experiment was carried out in agricultural research farm of zabol university, iran, during growing season of 2007-2008. the experiment was conducted in spilt plot using randomized complete block design with four replications. three irrigation regimes defined...
