in this study, the effect of drought and different concentrations of silicon was examined on seed yield, essential oil percentage and physio-chemicals properties in fennel plant. the experimental design was a split plot with three irrigation regimes: irrigation at 100, 70 and 40 percent of fc comprising the main treatments, and five levels of silicon foliar sprays (0, 2.5, 5, 7.5 and 10 mm) as ...

Pelargonium odoratissimum is a perennial evergreen used as a fragrant ornamental plant. Leaves, green branches and fresh flowers contain essential oils, that have been shown to possess antibacterial, antifungal, antiviral, insecticidal and antioxidant properties. In order to study the effect of foliar spray of ZnSO4 (0, 1000, 2000, 3000 and 4000 mg L-1) on vegetative growth and some physiologic...

Oil palm propagation techniques are juvenile pot plants derived from germinated seeds and tissue culture, because it doesn’t produce sucker. In the nursery stage, monitoring the conditions of irrigation and nutrition are important to ensure phenotypic quality. During the nursery stage, optimal fertilization in development of more vigorous and productive plants. This research was carried out to ...

in order to study the effect of  foliar application of zinc and iron on germination of soybaen seed under different level of irrigation, an experiment was conducted in 2009 at shahrekord agricultural research center. main factor was including of four levels of drought stress as irrigation (irrigation after 60, 80, 100 and 120 mm evaporation from class a evaporation basin) and sub factor was inc...

a field experiment involving red clover varieties k-39, k-17, una and viola was established on an acidic (phh2o 4.8) soil to evaluate the effects of foliar application of cobalt (a beneficial nutrient for efficient nitrogen fixation) on seed yield, and on seed yield components. the foliar spray of the crop was carried out using cobalt nitrate [co(no3)2] with the treatments: one application at t...

Shimizuomyces paradoxus showed no inhibitory effect against plant pathogen fungi, such as Fusarium oxysporum f. sp. lycopersici and Alternaria solani. The S. paradoxus culture filtrate showed higher seed germination and seedling growth rates in canola than distilled water and potato-dextrose broth. A conidial suspension of 1.0×10(4)/mL resulted in the highest growth stimulating effects on total...

A Split plot experiment based on randomized complete block design (RCBD) with three replications was conducted in 2012,Treatments were included the time of foliar application with 3 levels (tillering stage, heading stage and no spray (control)) as main factor and cultivars in 4 levels (Sardari, Rijav, Biseton and Rashid) as the second factor. Plant characteristics such as plant height, length o...

in this study, the effect of foliar spray with calcium chloride (0, 0.75, 1.5 and 3 g l-1) during 2, 4 and 6 weeks before commercial harvesting time of apple fruit cv. ‘gala’ and ‘delbarestival’ which trained in three different systems (v shape, hightech and cordon) was investigated. the results showed that types of training systems and foliar application of calcium can affect on fruits quality...

to study the effects of drought stress and foliar application with salicylic acid on yield andit’s components and percentage of essential oil of nigella sativa l., a field experiment was conducted as split plot based on randomized complete block design with three replications at research farm of shahid bahonar university of kerman during growing season of 2013- 2014. the main factor was drought...
