Abstract:
Microorganisms play an important role in maintaining soil and plant health. They act as biofertilizers and increase the resistance to biotic and abiotic stress. Sugarcane, like wheat, rice, corn and other grains, is of Gramineae family characterized by segmented stems, blade-like leaves, and reproduction by seed. Analysis of 21 sugarcane samples from fields of chunni kalan village (FATEHGARH SAHIB, PB) was done to study the density of microorganisms by standard plate count (SPC) method.Total viable counts of rhizospheric sample on Potato Dextrose Agar media were calculated to be 45x10⁷ cellg and samples on the nutrient agar were calcutaed to be 181x10⁷ cellsg of soil. Of the various microflora identified from the surface of these samples some are bacterium such as, Pseudomonas, Azospillum, Bacillus, Proteous some are fugus such as Penicillum, fusarium Aspergillus were found to be the pre-dominant species in most of the samples. On the basis of saccrholytic activity pseudomonas showed non saccrholytic, bacillus, showing weak saccrholytic Azotobacter, showing strong saccrholytic bacteria. Soil microbial population is immersed in framework of interaction known to affect the plant roots. Fungal and bacterial population helps the plant to maintain the nutrient level through their various interactions. Soil bioata multiplies rapidly when organic material, roots and their food sources are available, and also when the soil is moist and warm.
