Abstract

The present work was carried out during the two successive seasons 2008and 2009 in the experimental station of soil salinity and alkalinity laboratory, Alex., to study the effect of inoculation with the biofertilizers [Nitrobine+Phosphorein(NP) 1:1 w/w] at rates 0.0,2.5,5and 10g/plant and salinized water ( EC,2, 4 and 8 dSm-1 ) and their combinations on the growth, yield and chemical content of leaves and sepales of Hibiscus sabdariffa, L. plants. In addition soil EC, pH , SAR and NPK availability were determined. The results indicated that increasing rates of the biofertilizers Nitrobine+Phosphorein (NP) resulted in considerable significant increases in all growth parameters [plant height (cm), number of branches / plant, number of leaves, dry weight of leaves / plant (g)] and yield [number of fruits / plant, fresh and dry weights of fruits / plant(g)]. Anthocyanine pigments and vitamin C and total chlorophyll content and mineral content (N,P and K %) were increased. The highest increase in these characters were obtained from adding the biofertilizers at rate 10g/plant combined with EC,2dSm-1 saline water irrigation. Also, the increment applications of biofertilizers(NP) at any levels of irrigation water salinity imposed considerable reduction in soil pH, EC and SAR. In the contrary, soil available N,P and Kwere progressively increased with increasing application rates of biofertilizers(NP) at 5 and/or 10g/plant across salinity treatment. The highest value were performed with 10g/plant biofertilizers(NP) with saline water level of EC,2dSm-1
