Beauv) is important minor millet belonging to the family Poaceae. In India, the cultivation of foxtail millet is confined to Andhra Pradesh, Karnataka, and Tamil Nadu. It's grain used for human consumption and a feed for poultry and cage birds. It is used in several food preparations like chapati, fermented bread, biscuits, malts, etc. the stalks are used as fodder and for thatching. It is rich in micronutrients and good for diabetic patients. It protects against cancer and related heart diseases (Anon., 1993). Foxtail millet comes under drought tolerant crop and it can be grown as a short-term catch crop. It is adapted to a wide range of elevation, soils, and temperatures. It is usually grown in the marginal lands having low level of nutrients and organic matter. However, it responses to the amount of fertilizers used and they significantly contribute in yield and yield attributing characters. Fertilizer management is one of the important cost-effective factors known to augment the crop production. The supplementation of fertilizers along with the organic manure plays the key role in overall International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 8 Number 08 (2019) Journal homepage: http://www.ijcmas.com A field experiment was conducted during the kharif season of 2018 on Foxtail millet of varieties SIA 3156 and SIA 326 (PRASAD) at Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, SHUATS, Prayagraj (U.P). the experiment was laid out in Randomized Block Design with 6 treatments combinations, consisting of two varieties of Foxtail millet (SIA 3156, SIA 326) and nitrogen management viz., Farmer’s practice (NPK= 40:20:0), 100% RDF (NPK= 50:30:20)), 75% RD N + 25% N through PM, 75% RD N + 25% N through PM + Azospirillum SI, 50% RD N + 50% N through PM and 50% RD N + 50% N through PM + Azospirillum SI. The Experiment revealed that in variety SIA 3156, integration of inorganic fertilizer of 75% RD N through Urea + 25% N through PM + Azospirillum Seed Inoculation resulted in maximum grain yield (2.31 t /ha), higher Net return (₹ 32,229.35 /ha) and maximum B:C ratio (2.59). In variety SIA 326, the experiment reveals that 75% RD N through Urea+ 25% N through Poultry Manure found out to be the best treatment which result in highest grain yield (2.31 t /ha), highest Net return (₹ 25,946.09 /ha) and B:C ratio (2.28).
