Abstract:
The global food demands due to increasing population has increased the use of chemical fertilizers, however, this usage has proven extremely hazardous for human health as well for environmental conditions. To minimize the deleterious effects of chemical fertilizers, PGPR are used as biofertilizers, due to their eco-friendly nature. But there has always been an issue of their viability and required shelf life for successful application and for greater yields. In a developing country like Pakistan, we need to apply these biofertilizers in economic and effective way due to extreme variations in temporal conditions and non-availability of advance techniques at user end. In the current research work, actually tried to fill in the gap by selecting suitable carrier materials that are wheat bran and rice husk in combination with the consortia of rhizobacteria which is an advance strategy for improved shelf life and viability of biofertilizers. For this purpose, bioformulations were prepared by using an ample product of flour and rice milling industry i.e., wheat bran and rice husk as organic carrier materials for the consortia of spore forming and gram-positive rhizobacteria [Bacillus tropicus(LS5)] with non-spore forming and gram-negative rhizobacteria [Achromobacter denitrificans (HS4), Enterobacter sp., (AB7), Pseudomonas sp., (AH2)]. The phytostimulatory effects of metabolic diversity of inoculated PGPRs and their viability after 30 days of storage were illustrated by the increments in shoot length, number of leaves, fresh weight, total chlorophyll content and protein content and root architecture modifications of treated plants. The current research suggested Bacillus tropicus(LS5) and Achromobacter denitrificans (HS4) as best consortia and wheat bran is more effective carrier material as compared to rice husk, which encompasses the commercialization of bioproduct in developed and developing countries by keeping the cost effectiveness, consumer health friendly and environmental compatibility in balance.
