ABSTRACT

For highest yielding of the crop, the agriculture management is majorly dependent on the fertilizer, which contain inorganic matter and chemicals, which are hazardous to human health and the environment. Biofertilizer provides macronutrients as well as micronutrients during biological processes and provide favourable conditions for germination and initial growth. There are different Biofertilizers, which are available commercially. One of them is algal Biofertilizer which is the best alternative of the synthetic fertilizers, as they have the natural ability to fix the nitrogen into the soil. They are used as a biofertilizer in the cultivation of onion, rice and other cereals and pulses like (Vignaradiata, Cicer Arietinum, etc.). Some best microalgae biofertilizers are Spirulina Platensis and Chlorella Vulgaris. The growth parameters like plant height, leaf number, dry weight, biochemical composition, leaf area, neck thickness, bulb length, diameter and weight with the yield and growth found to higher when they are treated with these two algal biofertilizers. So this review article focuses on checking the effect of spirulina on the cultivation of onion.
