Abstract: This research was undertaken to determine the Influence of fodder pearlmillet (Pennisetum glaucum L.) varieties and nitrogen levels on post-harvest soil fertility. The experiment was conducted at the dry land farm of S.V. Agricultural College, Tirupati, Acharya N.G. Ranga Agricultural University during kharif, 2015 on sandy clay loam soils. Four Fodder pearlmillet varieties viz. Gaint bajra, BAIF bajra, Raj bajra chari-2 and APFB-09-1, Four Nitrogen levels viz. 75, 100, 125 and 150 kg N ha^-1 were laid out in factorial randomized block design with three replications. Results revealed that soil nutrient status after harvest i.e., available nitrogen, phosphorus and potassium were significantly affected by the varieties and nitrogen treatments. The highest post-harvest status of soil available nitrogen and phosphorus were recorded with the variety Raj bajra chari-2 followed by Gaint bajra, however for nitrogen, it was on par with that of APFB-09-1, while it was found to be the lowest with BAIF bajra. The post-harvest soil available potassium was the highest with Raj bajra chari-2 which was at par with Gaint bajra, while the lowest soil available potassium was observed with BAIF bajra. Application of 150 kg N ha^-1 recorded the highest post-harvest soil available nitrogen, phosphorus and potassium status, while the lowest values were registered with application of 75 kg N ha^-1.
