Evaluating Potential of Spirulina as Innoculant for Pulses

Many non-heterocystous cyanobacteria are also capable of nitrogen fixation and improve plant growth. Spirulina platensis and S. maxima at concentration of 500 mg and 1000 mg/kg soil were tested on two plants Phaseolus aureus and P. mungo. Growth was measured in terms of plant shoot lengths. The leaf chlorophyll content and protein content of the grains of both the plants were analyzed. Shoot length of both the plants were increased after 30 days. The leaf chlorophyll content and the protein content in the grains of the plants were not improved significantly. Conclusion was drawn that inoculation of Spirulina shows no beneficial effects in the crop plants.
