Effects of biofertilization with the Bacteria Bacillus subtilis and Pseudomonas flurescens on the growth and physiological features of Matricaria chamomile

Abstract

This study was conducted at the medical plants farm , and the animal house of the Collage of Pharmacy / Kerbala University . The aim was to investigate effects of biofertilization with Bacillus subtilis , Pseudomonas fluorescens and Bacillus subtilis + Pseudomonas fluorescens on the physiological features growth of Matricaria chamomile . The effects of biofertilization showed that there was a highly significant increase in the volatile oil percentage in (Bacillus subtilis + Pseudomonas fluorescens) treatment reached to 25.28% compared to control treatment , B. subtilis treatment, Ps. fluorescens treatment reached to 8.76% , 11.68% and 12.19% respectively. The results also showed increasing in the availability of essential elements which included (N , P, K, Ca , and Mg) and micro elements (Fe , Mn , Cu , Zn and) to dry leaves of Matricaria chamomile compared to control treatment . On the other hand , the results also showed increasing in the ratio of chlorophyll (A) and chlorophyll (B) and dry weight of flowers to M. chamomile in (B. + Ps.) treatment reached (1.553) gm compared to C, B. , Ps. Reached to (0.031) gm , (0.087) gm , (0.060) gm respectively .
