Effect of Organic and Bio N-fertilization on Growth, Productivity of Fig Tree (Ficus Carica, L.).

The present investigation was carried out during 2007 and 2008 seasons to study the effect of organic and bio N-fertilization on growth, productivity of fig trees grown in Ras - Elhekma, Matrouh Governorate. The aim of the present study was to investigate the combined effects of organic manure and bio N-fertilization on growth, productivity of fig tree. Applying poultry manure + azotobacter and poultry manure + azospirillum gave the highest number of new shoot, shoot length, leaf area, total chlorophyll, number of fruit per shoot, yield, fruit volume and fruit length in the two seasons. Also, the same treatments gave the highest TSS, acidity, total and reducing sugars content and leaf minerals content (N, P, K, Ca and Mg %) in the two seasons. The results clarified that poultry manure + azotobacter and poultry manure + azospirillum treatments gained best vegetative growth, productivity and fruit quality under this condition.
