Abstract

Field investigations were conducted during the summer seasons of 1999/2000 and 2000/2001 to study the responses of strawberry plants cv. Camarosa to different levels of nitrogen (0, 200,300 and 400kg N fed. -1 ), organic manure (0, 15, 20 and 25 m 3 fed. -1 ) and biofertilizer treatments (inoculation with or without Halex-2) as well as their interactions on yield potentials and fruit quality of strawberry. The two experiments were carried out on sandy soils under a drip irrigation system, at the Experimental Station Farm, South Tahrir, Hoticultural Research Station, situated at Behiera Governorate. The obtained results, generally, indicated that increasing of nitrogen or chicken manure applied rates was accompanied with significant increases for yield potentials; i.e, yield plant -1 , early yield and total yield fed. -1 ,and marketable yield fed. -1 as well as average fruit weight. On the contrary, the incremental additions of either nitrogen or organic manure tended to decrease total soluble solids, total titratable acidity and Vitamin C contents of strawberry fruits. Total sugars responded significantly and negatively to mineral nitrogen applications but it responded positively with increasing the chicken manure rates. The inoculation of strawberry transplants with Halex-2 biofertilizer improved strawberry fruit yield and its components, as well as, enhanced average fruit weight and total
