in order to evaluate the seed yield and qualitative traits and oil in some winter rapeseed (brassica napus l.) varieties as affected by micronutrient elements, this experiment was performed during 2011 - 2012 cropping seasons as split plot arrangement in randomized complete block design with three replications, in arak, iran. micronutrient fertilizers including of zero as check, fe, zn, mn, fe ...

to determine the effects of drought stress and fe and zn spraying on two annual medics, namely, medicago polymorph cv serena and medicago scutellata cv comertial, a field experiment as a split factorial based on a randomized complete blockdesign in 3 replications in allborze agricultural research center, in karaj was conducted. spraying treatments include distilled water (control), fe, zn and f...

abstract in order to study the effects of variety, water regime, zinc and cadmium levels on concentration, content and translocation of p, cu, fe and mn on rice, a factorial experiment was conducted consisting of four factors including: two varieties of rice (vandana and hashemi), two water regimes (flooded and nonflooded), three levels of zinc, and three of cadmium (0, 5 and 10 mg kg-1). the e...

18 1 (mean 28 mg kg). Spring wheat cultivars pos19 sessed higher Fe-grain concentrations than winter 20 wheats. By contrast, winter wheats showed higher 21 Zn-grain concentrations than spring genotypes. 22 Within spring wheat, a strongly significant positive 23 correlation was found between Fe and Zn. Grain 24 protein content was also significantly (P < 0.001) 25 correlated with grain Zn and Fe...

this research aimed to study on effect of foliar spraying with zinc (as zinc sulphate), nitrogen (as urea) and iron (as sulphate and chelated fe) on growth parameters, quality of fruit, flower characteristics, chemical constituents and nutrients content of leaves on grapevine. applied nutrients were zinc sulphate (zn) of 0.0 and 1.5gl-1 and urea (n) at 0.0 and 5 gl-1 and fe (1) control (low fe)...

melissa officinalis l. is a well-known medicinal plant from the family of lamiaceae. the plant is high in flavonoid. flavonoids of lemon balm such as rosmarinic acid and anthocyanin have an antiviral and antioxidant effect. micronutrients are the element that is necessary for the plant in low concentration. in this experiment the effect of micronutrient (fe and zn) was examined on the anthocyan...

Zinc toxicity and Zn-Fe interactions were studied in corn (Zea mays L. var. Barbecue hybrid) grown in hydroponic culture. High Zn greatly reduced the root and shoot fresh weights; increasing Fe largely, but not completely, restored normal growth. Correlation analyses of root and leaf Zn and Fe contents suggested that Zn may interfere with the translocation of Fe; however, Zn toxicity was not as...

The Thriposha programme is a community-level nutrition intervention in Sri Lanka that provides a combination of energy, protein and micronutrients as a 'ready-to-eat' cereal-based food. We measured the bioavailability of Fe and Zn from Thriposha formula at two different molar ratios of Zn:Fe in order to determine the effect on Fe and Zn absorption. Children 4-7 years (n 53) were given a meal pr...

This Research aimed to study on effect of foliar spraying with zinc (as zinc sulphate), nitrogen (as urea) and iron (as sulphate and chelated Fe) on growth parameters, quality of fruit, flower characteristics, chemical constituents and nutrients content of leaves on grapevine. Applied nutrients were zinc sulphate (Zn) of 0.0 and 1.5gl-1 and urea (N) at 0.0 and 5 gl-1 and Fe (1) control (low Fe)...
