The effect of green manure and biofertilizer by using (Lupinus albus and
Lupinus albu s + Rhizobium) on some soil properties and potato growth and
production during two successive seasons of 2007/2008 and 2008/2009 was
studied. The results showed
that green manure provided the soil with 3.75
kg/m2 green organic matter including (398 g dry matter and 14 g nitrogen),
while lupinus albus + Rhizobium provided the soil with 4.55 kg/m2 green
organic matter including (581 g dry matter and 22.3 g nitrogen) and improved
soil chemical properties. The results showed as well that biofertilizer significant
improved potato growth parameters: plant and tuber dry matter, foliage
surface, foliage index, plant length, plant elements content (N,P,K,Ca and Mg),
tuber number and their content of nitrate and protein .The results showed as
well that biofertilizer significant improved marketing potato yield.
Some species of the Syrian Flora were waned, other were extincted.
therefore, it was so nessesary to make a releve for restrict and classify the
survival species in order to put them under conserving & improvement genetic
program. The aim of this
research was to study the plant diversity in West
Homs; one of important basaltic region in Syria, and to concentrate on the wild
legumes and the Rhizobium strains which cohabit with. A plant survey was
carried out showed the existence of 365 species belong to 202 genera and 51
families, 15 species are endemic.12 species not observed previously in Syria but
are found in Lebanon were recorded,in addition another 3 species not listed at
all neither in Syria nor in Lebanon were mentioned. The geobotanical
attributes and the economical importance of the gathered species were
determined.as so as systematic keys of the most important families were
suggested...The root nodules of 10 species belong to 10 genera of wild legumes
were studied. Rhizobium strains were isolated and cultured in vitro. The
morphologic characters were studied microscopy. The pure strains were
reserved by refrigerator.
