Effect of Rhizobacteria on Wilt Suppression, Growth Promotion and Yield of Coriander and Fennel

Abstract

A study was carried out to demonstrate the use of rhizobacteria and its effect on disease suppression, growth promotion and yield of coriander and fennel at Raigarh, Chhattisgarh, India. The use of rhizobacteria strains FK-14 (Pseudomonas putida) and FL-18 (Macrobacterium paraxidum) as seed and soil application resulted in minimum wilt incidence (13.83 and 13.63%, respectively), maximum mean plant height (84.03 cm and 84.39 cm, respectively), weight of 1000 seeds (18.30 g and 18.53 g, respectively), and seed yield (8.75 q ha^−1 and 9.95 q ha^−1, respectively) in coriander crop. In fennel crop also, seed and soil application of both the strains of rhizobacteria resulted in higher mean plant height (106.1 cm and 105.3 cm, respectively), weight of 1000 seeds (11.30 g and 11.50 g, respectively) and seed yield (9.5 q ha^−1 and 9.6 q ha^−1, respectively), compared to other treatments. The application of these two rhizobacteria as seed and soil application was found to be significantly superior to their exclusive application and that of other agents like Trichoderma
