Micro biota and organic amendments improve Sesame indicum Quality and quantity in sandy soil

The study focuses on effect of the complementation between the plant growth promoting rhizobacteria (PGPR) such as Streptomyces erythrogriseus 2, Bacillus cereus 54-1, and Spirulina platinsis on the growth and the quantity of oil sesame under different rates of familiar manure 0, 2, 4 ton/fed. Results indicated inoculation mixture of Bacillus cereus54-1, Streptonyces erythrogreiseus sp 2 and Spirulina platinsis had the greatest effect on dehydrogenase activity (254.0 μg TPF/g dry soil), while root colonization Bacillus cereus54-1, the uppermost values with 60 % colonization. The photosynthetic test was carried out where implementation of all microbes resulted in the highest chlorophyll a content with 2.03 mg/ g dry weight. Growth parameters was estimated, the treatment of bacteria Bacillus cereus54-1, Streptonyces erythrogreiseus sp 2 gave the highest values of Root length, Shoot height, number of branches and shoot dry weight were 22.1,22.2 cm/plant root length 153,156.2 cm/plant shoot height,4.5,4.5 number of branches and 50.3,49.4 gm./plant shoot dry weight. Bacillus cereus54-1, Streptonyces erythrogreiseus sp 2 gave the highest values of shoot height, number of pods weight of 1000 seed and seeds Kg/fed number being, 169.7,159.0 cm/plant, pods number /plant and 5.4,5.97 weight of 1000 seed/plant, and 5.8,5.67seed Kg/Fadden respectively. However, the highest values of N, P and K were, 17.29, 7.9 and 62.20 (mg.kg-1 soil) obtained under the treatment of bacterial Bacillus cereus54-1, respectively. The highest seed oil percent was observed in treatments Bacillus cereus 54-1 and Streptomyces erythrogreiseus sp 2 where the heights seed oil percent was 51,48 Kg/fed compared to the control.
