Abundance of Cyanobacteria from Maize Fieldsofsangola Tahasil in Solapur

Fertility of soil depends upon its composition of nutrients and biotic factors such as algae, fungi and microorganisms which helps in recycling of nutrients. Composition of Blue-green algae also makes a major contribution to the fertility of the soil. It has been suggested that blue-green algae (BGA) assist higher plant growth by supplying growth substances. There are numerous works about roles of blue-green algae on growth of maize fields. Increase in use of synthetic fertilizers in the field badly affected the fertility of the soil. These synthetic fertilizers are effecting on flora and fauna of the field responsible for productivity of the crop plants. Efforts were made to evaluate dosage of fertilizers and occurrence of blue green algae. During the investigations, 23 species belonging to three families of heterocystous and non-heterocystous of blue green algae were encountered from Sangola Tahasil of Solapur.
