“…Particularly, seed soaking in Azospirillum @1:50 and PPFM @1:100 dilutions of seed respectively. Similar findings of co-inoculation of bacterial cultures on improvement in seed germination and seedling vigour were studied by many workers [8,19,28,29]. Qureshi et al [8] found that the co-inoculation of phosphate solubilizing bacteria and rhizobia increased the root length, root mass, number of nodule and mass in mash bean.…”

Aim: Seed treatment with Plant Growth Promoting Bacteria (PGPB) is considered to be safe for seed and environment and ecologically sound. To ensure the benefits of the PGPB, studies were conducted in pearlmillet by treating with liquid microbial cultures for enhancing seed germination and seedling vigour. Methods: The pearlmillet seeds were infused with different concentrations of liquid microbial cultures and their consortia. Also, the bioinoculant infused seeds were treated with chemicals to assess their effect on the microbial population. Results: The pearlmillet seeds soaked in equal volume of Azospirillum or phosphobacteria @ 1:50 dilution or Pink Pigmented Facultative Methylotroph (PPFM) @ 1:100 dilution for 18 h have recorded higher germination and seedling vigour. Pink Pigmented Facultative Methylotroph treated seeds have showed higher germination and seedling vigour amid the microbial cultures. In addition, the bioinoculant treated seed viability and vigour were not affected during three months storage. However, the microbial populations in the seed get declined during storage. The microbial consortia comprising of Azospirillum, phosphobacteria and PPFM did not affect the germination rather seedling vigour. Besides, seeds infused with Azospirillum @ 1:50 dilution and PPFM @1:100 dilution (1:1) for 18 h have recorded higher seedling vigour. In addition, seeds soaked in PPFM @1:100 dilution for 18 h followed by polymer coating @ 5 ml kg-1 and carbendazim seed treatment @ 2 g kg-1 of seed had higher germination and seedling vigour. But, the microbial population in the seed was reduced considerably due to the chemical treatment. Conclusion: The liquid bioinoculants viz., Azospirillum, phosphobacteria and PPFM can be used to pre-inoculate the pearlmillet seeds with required population to be carried over to the field.

“…This research finding of compatibility of biofriendly polymer with P. fluorescens was in conformity with the previous finding who have reported that the compatibility of P. fluorescens with biofriendly polymer [13,14] and also in conformity with Chin et al, [17] who stated that all the biopolymers were compatible with P. fluorescens. The pre-inoculated seed treatment with polymer coating has not affected the microbial population in the seed [19]. Cts-PEG film containing with Trichoderma increased their population when applied in the soil, by the degradation of hydrolytic enzymes of chitosan film served as the nutrient source for Trichoderma [20].…”

An efficient biological seed coating begins with the choice of a suitable polymer. Experiments were conducted at the Department of Seed Science and Technology, Professor Jayashankar Telangana State Agricultural University, Hyderabad, to determine the compatibility of commercial polymers and biocontrol agents. Five polymers commercially used by the seed industry were procured from seed companies. Three bioformulations were purchased from the commercial biofertilizer units and the pure cultures of Trichoderma viride, Pseudomonas fluorescens, and Bacillus subtilis were isolated from the bioformulations through serial dilutions, culturing and subculturing on microbial media. The compatibility of commercially used polymers has been tested with biocontrol agents using poisoned food technique (for fungal bioagents) and the inhibition zone technique (for bacterial bioagents). Observations on the reduction in radial growth of the fungal bioagent and zone of inhibition of bacterial bioagents was recorded in mm. The results revealed that all the 5 polymers commercially used by the seed industry were tested to show 96–100% compatibility with Trichoderma viride, 100% compatibility with Pseudomonas fluorescens, and 95–100% compatibility with Bacillus subtilis. These findings indicate that there is a greater compatibility of all the commercial polymers used in the seed industry with the bioagents which can also be used for effective seed coating with bioagents economically without incurring any additional inventory from the part of the industry.
