Abstract
2009/2010 and 2010/2011at the Experimental Farm of the Faculty of
Agriculture, Minufiya University. This study included two parts ,the first one
was dealing with studying the response of caraway plants grown under field
conditions to four kinds of comerical biofertilizer namely (Microbein,
Biohumein, Rhizobacterein and Nitrobein) and chemical nitrogen fertilization
in the form of urea (46% n) at rates of 0.0, 60, 120 and 240 kg/fed separately
or in combinations with the biofertilizers.
The second part in this investigation was carried out in pots 30cms
diameter and filled with 4.5kg air dried soil/pot for studying the effect of soil
salinity levels at rates of 0.0, 0.10%, 0.20% and 0.30% and irrigation with
either magnetized water or with ordinary water (non magnetized) separetly or
in combinations on the growth, fruit yield, essential oil production and
chemical constituents of caraway plants. The results of the first part of
investigation showed that the application of the biofertilizer Biohumein or the
moderate level of urea (120 kg/fed) separetly or together resulted in the best
growth, fruit yield, essential oil production and the measured chemical
constituents of the plant (N, P and K% and total carbohydrate percentage in the
dried herb and photo synthetic pigments content in the leaves) when compared
to the other treatments in the two growing season. Regarding the results of the
second experiment ,it could be concluded that irrigating caraway plants with
magnetized water improved growth parameters, fruit and essential oil
production as well as the measured chemical constituent of the plant (N, P and
K%, total carbohydrate percentage and photosynthetic pigments content in the
leaves). In comparison with irrigation with non magnetized water. Furthermore,
irrigation with magnetized water reduced the harful effect of soil salinity on the
previously mentioned measurements of caraway plants in comparison with
those irrigated with non magnetized water in the two growing seasons.
