摘要：

Phosphate solubilizing microorganisms play an important role in balancing plant nutrition through enhanced availability of phosphorus (P) to roots. These microbial strains convert the insoluble phosphates into soluble forms. Phosphate solubilizing bacteria (PSB) were isolated from the saline soil of fennel (Foeniculum vulgare Mill.) cultivation fields under semi-arid climate of Rajasthan, India. Nine native PSB isolates were applied to study their influence on fennel seed yield and essential oil content. Significant effect of different PSB isolates on seed yield of fennel crop was recorded. The highest seed yield (2148.66 kg ha(-1)) was recorded with Bacillus subtilis NRCSS-II (PSB-36) and the lowest seed yield (1744.35 kg ha(-1)) was observed with Bacillus sp. PS-1 (PSB-20) which was at par with control. The highest essential oil content was recorded with Bacillus sp.Fen-17 (PSB-26) (2.80%) as compared to control (2.09%). Though application of all the PSB isolates resulted into increased essential oil yield as compared to control but Bacillus subtilis NRCSS-II (PSB-36) resulted into enhanced seed yield and essential oil both. Biochemical assay of the post harvest soil samples revealed that applied PSB isolates caused significant effect on various soil parameters as compared to control. The organic carbon, N, P, K, and EC increased to 0.59%, 78.25 kg ha(-1), 28.54 kg ha(-1), 178.3 kg ha(-1) and 0.99 dS m(-1) as compared to control. On the other hand soil reaction (pH) declined to 7.25 as compared to control. (C) 2016 Elsevier B.V. All rights reserved.
