The six (6) treatments of nitrogen of organic sour viz. 100% N through 1/3 vermicompost+1/3 FYM+1/3 poultry manure at basal (T1), 100% N through vermicompost at basal (T2), 100% N through poultry manure at basal (T3), 100% N through 1/2 poultry manure as basal + 1/2 vermicompost at 30 DAT (T4), 100% N through 1/2 vermicompost as basal+ 1/2 vermicompost at 30 DAT (T5) and Control - No application of any nutrients (T6) were tested in randomized block design with four replications. The growth, yield attributing characters and yield of scented rice was significantly highest noted under treatment 100% N through 1/3 Vermicompost+1/3 FYM+1/3 Poultry manure at basal (T1), which was at par to treatment 100% N through 1/2 poultry manure as basal + 1/2 vermicompost at 30 DAT (T4). Keywords: Scented rice, organic nitrogen sources, growth and yield 1. Introduction Rice (Oryza sativa L.) occupies a pride place among the food crops cultivated and it has not only meets most of the needs on earth but also symbolizes revolution, industrialization, calorie and earth. It is the cause of revolution on earth in nutrition as well as on food security front (Pradhan and Moharana, 2015) [14] . In India, during the past three decades, intensive agriculture involving high yielding varieties of rice has lead to heavy withdrawal of nutrients from the soil. Further, imbalanced use of chemical fertilizers by farmers has also deteriorated soil health and declines soil organic carbon content, which is threat to sustainability. Nitrogen is commonly the most limiting nutrient for crop production in the major world’s agricultural areas and therefore, adoption of good N management strategies often results in large economic benefits to farmers. Use of organic manures in present agriculture is increasing day by day, because of its utility not only improving the physical, chemical and biological properties of soil but also maintaining the good soil health and supplying almost all essential plant-nutrients for growth and development of crop plants. So, it is time to look for measures to stimulate sustainability in production of rice on long- term basis. Organic manures like FYM, poultry manure and vermicompost deserves priority for sustained production and better utilization in organic rice production (Dahiphale et al., 2003) [4]. Organic farming is also preferred because of increasing consumer demand for safe, high quality, ethical organic foods and good monetary returns. There is a great demand for high quality products and organically grown foods in the international market and can capitalize on its potential to go for organic farming on a large scale. India had the least percentage of cultivated area under organic farming. There is thus considerable scope to increase the area under organic farming in India. The total volume of export during 2015-16 was 263687 MT. The organic food export realization was around 298 million USD (APEDA, 2015) [2] . The area under scented rice varieties is increasing day by day with the opening of the world market as well as increased domestic consumption due to their premium quality (Singh et al.,2008) [17] . Scented rice occupies a pivotal position in world because of their high quality and therefore earns premiumprices. In rice growing areas, organically produced scented rice has better scope to obtained better market price as well as good export opportunity. Keeping this in view, the present investigation was conducted to estimate growth and productivity of organically grown scented rice.
