Abstract:

A study was conducted to evaluate the potential of fluorescent Pseudomonas isolates against important endemic diseases of barnyard millet. A total of ten pseudomonad isolates, collected from rhizospheric soil samples of barnyard millet, were studied, out of which three fluorescent Pseudomonas isolates (UUHF Psf- 1, UUHF Psf-2 and UUHF Psf-4) were selected for testing under heterogeneous field conditions on the basis of their in vitro performance against the conducted biocontrol traits viz., Phosphate solubilzation test Siderophore production test and HCN production test. A field experiment was thus carried out in a completely randomized block design with three replications and seven treatments including untreated control. Maximum grain smut disease control (91.92%) and brown spot disease control (75.99) was recorded in the treatment T4 (Soil application of value added vermi-compost impregnated by fluorescent Pseudomonas isolate UUHF Psf- 4 + Seed treatment with fluorescent Pseudomonas isolate UUHF Psf- 4 + One foliar spray with fluorescent Pseudomonas isolate UUHF Psf- 4 at the time of 50% flowering). Maximum grain yield (23.13 q/ha), highest per cent increase in grain yield (64.86%) and highest per cent avoidable loss (39.34%) was also recorded in the same treatment T4. Treatment T6 (Soil application of value added vermicompost impregnated by fluorescent Pseudomonas isolate UUHF Psf -1+ Seed treatment with fluorescent Pseudomonas isolate UUHF Psf- 1 + One foliar spray with fluorescent Pseudomonas isolate UUHF Psf- 1 at the time of 50% flowering) was next best treatment and recorded 70.96 % grain smut disease control and 63.98 % brown spot disease control, 32.77 % avoidable los and 48.75 % increase in grain yield over untreated control (T8). All the tested treatments were found economical and significantly superior in comparison to untreated control in suppressing the grain smut and brown spot diseases and enhancing the grain yield in Barnyard millet though the findings were better in treatment T4 in most of the parameters studied under present experimental conditions. This research merits attention and could additionally open the avenue for the use of above mentioned fluorescent Pseudomonas isolates in suppressing the most destructive diseases of Barnyard Millet at the mid hill regions of Uttarakhand.
