Iodine (I) biofortification of vegetables by means of soil and foliar applications was investigated in field experiments on a sandy loam soil. Supply of iodine to the soil in trial plots fertilized with potassium iodide (KI) and potassium iodate directly before planting (0, 1.0, 2.5, 7.5, and 15 kg I ha(-1)) increased the iodine concentration in the edible plant parts. The highest iodine accumu...
To investigate how N-fertilization affects the growth, carbon and nitrogen (N) physiology, and wood properties of poplars with contrasting growth characteristics, slow-growing (Populus popularis, Pp) and fast-growing (P. alba×P. glandulosa, Pg) poplar saplings were exposed to different N levels. Above-ground biomass, leaf area, photosynthetic rates (A), instantaneous photosynthetic nitrogen use...
Effect of foliar fertilization with zinc and manganese sulfate on yield, dry matter accumulation, contents in leaf seed chickpea (Cicer arietinum)Soheil Kobraee
The application of nutrient solutions to the foliage plants is an alternative means fertilise crops. Foliar fertilisation used overcome disadvantages soil applications. Variable plant responses these foliar spray have often been described in literature. However, knowledge about penetration mechanisms, role a leaf-applied inorganic or organic solution, and results obtained by its still limited. ...
We used whole-tree, open-top chambers to expose 13-year-old loblolly pine (Pinus taeda L.) trees, growing in soil with high or low nutrient availability, to either ambient or elevated (ambient + 200 micromol mol-1) carbon dioxide concentration ([CO2]) for 28 months. Branch growth and morphology, foliar chemistry and gas exchange characteristics were measured periodically in the upper, middle an...
