Effect of biofertilizers and nitrogen leveles on the productivity and quality of Chinese garlic under sandy soil conditions [electronic resource].

Includes references.

This study was conducted on garlic (Allium sativum L.) cv. "Sids- 40 plants during two successive seasons (1999-2001). The study aimed to evaluate the effect of soil dressing with chemical nitrogen levels ( 0, 40.80. 120 and 160 kg N/fed), either single and I or in combinations with N- biofertilizer " Rhizobacterin" at 2 or 4 kg! fed, on the plant growth, yield and chemical constituents of bulbs and their storability during six months. The obtained results showed that applied N significantly increased vegetative growth and yield parameters. The increments were corresponding to the increase of N levels up to 120 kg/fed which was approximately similar to 160 kg! fed Biofertilizer treatment at the rate of 4 kg/fed was more effective than at the rate of 2 kg /feddan.
