The tomato, worldwide consumed food for its health effects and taste possess a major demand due to the increasing population and diminishing of cultivable lands. In addition, The increasing demand of agricultural products not only urges to find out the way to increase the yield in huge quantities but also strictly affirms the nature of the product yielded should be devoid of chemical fertilizers as it imparts hazardous effect to its agricultural field to which it was directly applied and as well as the consumers as minute proportions of these still remains inside the edible portion and causes a health defect over a period of consumption. Hence an effort was made to find out the feasibility of yielding high quantity of tomato by applying the non-hazardous microalgal based biofertilizer to augment the chemical usages. The tomato plant was treated with three different kinds of microalgal treatments to find out the most suitable method of application. All the three different techniques employed yielded a maximum growth when compared with the control plants, Among which the treatment three, the combined treatment of microalgae C. vulgaris and cow dung gave constructive results followed by the, soil drench method and foliar spray method. Thus the microalgae were evidenced for its biofertilizing potential and the same can be better utilized to explore the promising fertilizing agent as an eco-friendly and non-hazardous agent.
