Effect of bio-fertilizer, nitrogen sources and with interaction on plant growth, yield and quality of lettuce [electronic resource].

Includes references.

Two field experiments were carried out during the two successive winter seasons of 2000-200 I and 200 1- 2002 at the Agriculture Experimental Station Faculty of Agriculture - Cairo university at Giza to study the effect of using bio fertilizer and nitrogen sources as well as their interaction on vegetative growth characteristics, yield and quality of Lettuce cv: Balady. Obtained results show that bio - fertilization increased the plant growth of Lettuce plants expressed as plant height, leaves number, chlorophyll reading and total nitrogen, phosphorus and potassium content in the leaves as well as average fresh head weight and total yield. However. it decreased the nitrate content of Lelluce leaves.
