Abstract
Two Field experiments were carried out in sandy soil at the Experimental Research
Farm, Faculty of Agriculture, Suez Canal University, Ismailia Govemorate.
This study was conducted on Chinese garlic (Sids - 40) plants during the winter
growing seasons (199912000 and 2000 /2001). It aimed to evaluate the effects of soil
dressing with chemical nitrogen levels (0, 40, 80, 120 and 160 kg/fed), either single
and I or in combinations with N - biofertilizers (Rhizobacterin) at 2 - 4 kg/fed, on the
plant growth, yield and its components, as well as some chemical constituents in bulbs
and their storability under normal conditions .
The obtained results could be summarized as follows:
• Increasing the applied N-fertilizer levels from °to 160 kg/fed led to significant
increases in all tested characteristics of plant growth. Besides, application of Nfertilizer
levels from 40 up to 120 kg/Fed significantly increased total yield and its
components and improved chemical constituents in bulbs and their storability.
. Applications of biofertilizer (2- 4 kg/fed) exerted significant increases in plant
growth, total yield and its components. Moreover chemical content and storability
of bulbs improved compared with the control treatments. Further more, treatment of
biofertilizer at 4 kg/fed was more effective than 2 kg/fed .
The positive interactions between N-fertilizer levels and biofertilizer
(Rhizobacterin) treatments were often observed ,
Conclusion:
The best results were obtained by using 80kgN/fed with biofertilizer at
4 kg / fed under sandy soil condition in Ismailia Region .
