Trace elements or micronutrients play a major role in the metabolism of both plants and humans.Zinc has a major specific role in metabolism when compared with other elements. The microbialbiofertilizers are applied in the form of seaweed liquid extracts, microbial inoculants, biostimulatorsand biofortification agents. All these categories of microbial biofertilizers are involved in theenhancement of plant nutrient uptake. In the present study, Spirulina platensis is used as a biofortificationagent to enhance zinc levels in cultivars of Amaranthus gangeticus, Phaseolus aureus andTomato. Different experimental methods were followed including soaking seeds in different concentrationsof Spirulina 5, 10, 15, 20, 25 and 30 g in 100 ml of water; soaking seeds in Spirulinahydrolysate at different time intervals 1, 2, 3, 4, 5 hrs and overnight; Spirulina in combinationwith biofertilizers, chemical fertilizer, organic fertilizer and vermicompost in various proportions25:75; 50:50; 75:25 and foliar spray with different concentrations of Spirulina 25, 50, 75, and100g in 5 litres of water respectively. The zinc content of the yield of the cultivars was estimatedand the study results indicated that there was a significant increase in zinc levels with p-value0.015, 0.003 and 0.035 for Amaranthus gangeticus, Phaseolus aureus and Tomato respectivelywhen compared with the control and between the set-ups, with biofortification of Spirulina platensis.The obtained results emphasize the application of Spirulina platensis to enhance the mineralnutrient in plants which are non-polluting, inexpensive, utilizable renewable resource tomaintain the soil fertility.
