Abstract:
The objective of the conducting this study was to evaluate co-inoculation effects of Acetobacter diazotrophicus and phosphate solubilizing fungus on growth, nutrient uptake and yield of sorghum, which showed that dual inoculation of Acetobacter diazotrophicus @ 25 g kg-1 seed and phosphate solubilizing fungus @ 10 g kg-1 seed along with application of 75% of recommended dose of nitrogen, phosphorus and 100% recommended dose of potash had profound effect on growth, nutrient uptake and yield of sorghum. However, this treatment did not differ significantly from the treatments consisting of seed treatment of sorghum with Acetobacter diazotrophicus + phosphate solubilizing fungus along with application of 100% of recommended dose of nitrogen, phosphorus and potash; the treatment consisting of Acetobacter diazotrophicus + phosphate solubilizing fungus along with application of 50% recommended dose of nitrogen, phosphorus and 100% of recommended dose of potash; the treatment of phosphate solubilizing fungus with 100% recommended dose of nitrogen, phosphorus and potash and, the treatment consisting of phosphate solubilizing fungus with 100% recommended dose of nitrogen, potash and 75% recommended dose of phosphorus Thus, all these treatments were found to be equally effective in germination percentage, enhancing growth, height of plants etc. and significantly superior over rest of the treatments.
