Drought is one of the most important factors limiting crop yield and foliar application of phytoprotectants is an important management strategy for increasing crop resistance to drought stress. This research was conducted at Rice Research Station of Tonekabon, Iran, in 2018 by using a split-plot based on a Randomized Complete Block Design (RCBD) with three replicates. Main plots were irrigation...
Given that an effective combined foliar application of iodine (I), selenium (Se), and zinc (Zn) would be farmer friendly, compared to a separate spray each micronutrient, for the simultaneous biofortification grain crops, we effectiveness foliar-applied potassium iodate (KIO3, 0.05%), sodium selenate (Na2SeO4, 0.0024%), sulfate (ZnSO4∙7H2O, 0.5%), separately in their combination (as cocktail) m...
two laboratory and greenhouse experiments were carried out to compare and evaluate the nutrition of phaseolus vulgaris l. plant with foliar spray and root media. in laboratory, effect of four treatments; n- nutrition solution; urban solid waste leachate (uswl); vermi-compost extract and control (distilled water) on germination and seeding growth of phaseolus vulgaris l. was examined for 10 days...
One of the negative effects of water stress on growth and crop production is micronutrient uptake reduction by plant root. Therefore, to evaluate the effect of foliar application of Fe and Zn on some physiological and morphological characteristics of red bean (Akhtar cultivar) under drought stress this experiment was designed as a split plot in a completely randomized block design with three re...
To combat an increasing abundance of sucking insect pests, >40 pesticides are currently recommended and frequently used as foliar sprays on row crops, especially cotton. Foraging honey bees may be killed when they are directly exposed to foliar sprays, or they may take contaminated pollen back to hives that maybe toxic to other adult bees and larvae. To assess acute toxicity against the honey b...
zinc has previously been reported to alleviate salinity stress in plants. in this study, we monitored various biomass and chlorophyll fluorescence parameters to determine the optimum zinc sulfate concentration that can be used as foliar spray to alleviate salinity stress in glycine soja. the plants subjected to a series of salinity levels (nacl concentration of 0, 100, 200, and 300 mmol l-1), a...

This research was done to investigate the effects of Nano-iron spray, the chemical synthesis of silver nanoparticles and the green synthesis of silver nanoparticles on chamomile plant( Tanacetum parthenium). It was done in the form of a completely random factorial design with three replications in the greenhouse of the agricultural college of Zabol university. The treatments included the first ...
In a field experiment, the effects of foliar application of silicon (sodium silicate 6mM) on yield and yield components of wheat cultivars (Shiraz, Marvdasht, Sirvan and Chamran) and also canopy temperature depression (CTD) under water stress conditions (F.C, 60 and 40% F.C.) were investigated during 2012- 2013 growing season using a split split plot as randomized complete block design with thr...
the current study was conducted in order to evaluate the effect of mono and di-potassium phosphate combination (mdkp) on some quantitative and qualitative characteristics of iranian pomegranate (cv. malas-e-saveh) in pomegranate research center of saveh city, in 2012. to adjust the ph of the solution, the mono potassium phosphate and di-potassium phosphate combined with each other in the ratio ...
