Abstract: The present investigation entitled “Influence of different levels of nitrogen and Azospirillum inoculation on direct seeded rice in a Vertisol” was carried out in the experimental filed (Vertisol) of the Department of Soil Science & Agrilcultural Chmeitry, JNKVV, Jabalpur during Kharif 2015. The experiment was laid out with total 8 treatment combinations replicated thrice under randomized block design in different 24 plots each of 3 m x 4 m. The treatments were constituted with different combinations of 3 levels of fertilizer nitrogen (50, 75 and 100% of recommended dose of N) and inoculation of carrier based Azospirillum (as inoculated and uninoculated) including one control of unfertilized and uninoculated. The response from the treatment of RDN75%+Azospirillum was recorded statistically superior in enhancing growth of the crop viz., length of root and shoot, chlorophyll content, number of tiller/hill and other plant growth parameters. The same treatment combination of RDN75%+Azospirillum was found statistically and economically best to increase yields of grain and straw of paddy by 110.58 and 39.44%, respectively. While the treatment of RDN100%+Azospirillum exhibited numerically higher values for the above parameters but these were at par to that of RDN75%+Azospirillum.
