A systematic study of distribution pattern and diversity of algae of vegetable crop fields has been carried out from December 2012 to May 2013 at Irongmara and Barjalenga in Cachar district, Assam. A total of 51 species representing 26 genera were recorded under Chlorophyceae, Bacillariophyceae and Cyanophyceae from the different sampling sites. of these, 22 species belonged to Cyanophyceae, 24 species belonged to Bacillariophyceae and 5 species belonged to Chlorophyceae. The soil pH was found to be mildly acidic in all the plots. It has been observed that Bacillariophyceae contributed major share to soil algal population. Among the species detected, the most dominant are A nabaena, Nostoc, Chroococcus, Oscillatoria, Scenedesmus, Haematococcus, Chlorella, Navicula, Cymbella, and Nitzschia.
