Persimmon is a typical fruit crop of the Mediterranean region and, since it considered minor species, little information available on its nutrients need. In present experiment, was estimated quantity removed and recycled by Kaki Tipo Rojo Brillante, two main varieties persimmon grown in Emilia-Romagna (Po Valley, Italy). Plants from ten mature orchards were selected harvested; organs (leaves su...

The earliest land plants were short, herbaceous plants that evolved from primitive, water-living ancestors. For these plants, the change from a predominantly aquatic to a terrestrial environment was accompanied by the need for additional structural support to keep the plants upright and the need for more efficient transport of water to the aboveground parts of the plants. Larger plant sizes als...

In order to study the effects of different salinity levels on turnip (Brassica rapa L.), an investigation was conducted at Yasouj University, Iran, in 2010. The effects of four salinity levels including 1.92, 9.87, 19.6 and 21.94 ds m-1 (20:1 ratio of NaCl: CaCl2 in Hoagland solution) on germination, vegetative and maturity stages of turnip (Baherghan landrace) were investigated. The results re...

An infection of the fungus Moniliophthora perniciosa in cocoa trees reduces productivity plant. In this study, concentrations mineral nutrients healthy leaves and vegetative broom plant were determined, relationship between disease nutritional composition was assessed. The samples analyzed using wet digestion method determined by inductively coupled plasma optical emission spectrometry Kjeldahl...

Spirulina is a microalga cultivated in many countries. It source of valuable protein, polyunsaturated fatty acids, vitamins, antioxidants and elements. We have not found studies that address the effect supplement form or cultivation method on mineral content spirulina supplements. The aim this study was to determine whether (tablet powder) (organic conventional) bearing nutrients content. Such ...

[1] Chemical weathering is an integral part of both the rock and carbon cycles and is being affected by changes in land use, particularly as a result of agricultural practices such as tilling, mineral fertilization, or liming to adjust soil pH. These human activities have already altered the terrestrial chemical cycles and land-ocean flux of major elements, although the extent remains difficult...

heavy metals are aggressive environmental pollutants. they are easily taken up by plants and they are strong stress factors for plant metabolisms. heavy metals influence includes also disturbances in plant mineral nutrition by competition with other nutrients. the specific objective of this research work was to study whether elevated cr (vi), cd and pb contamination caused an unbalanced nutriti...
