A field experiment was conducted under the temperate conditions of Khudwani, Anantnag, Jammu and Kashmir in the rainy (kharif) season of 2015 and 2016, to study the influence of nutrient-management practices on performance of scented rice (Oryza sativa L.) under. The experiment comprised 2 scented rice varieties, i.e. ‘Pusa Sugandh 3’ and ‘Mushkbudji’ evaluated under 8 nutrient-management practices. In general, ‘Pusa Sugandh 3’ showed significantly higher values of yield and yield attributes, quality parameters, nutrient concentration and their uptake compared to ‘Mushkbudji’. However, ‘Mushkbudji’ recorded higher 1,000-grain weight and head-rice recovery than ‘Pusa Sugandh 3’. Application of recommended fertilizer dose (RFD) 60, 40, 20 kg N, P, K/ha + farm yard manure (FYM) @ 5 t/ha + vermicompost (VC) 2.5 t/ha resulted in significantly higher number of panicles, with an overall increase of 12.45% and 23.35% over the RFD and control respectively. Same treatment also resulted in significantly higher grain yield than the other treatments. Among the nutrient-management practices, combined application of VC and FYM along with 75% RFD recorded significantly higher values of amylose content, protein, L: B ratio after cooking over the treatments, RFD and the control. However, head-rice recovery was significantly higher with 75% RFD + 2.5 t/ha VC over the control and RFD + FYM 5 t/ha + VC 2.5 t/ha. Of the nutrient-management practices, the application of RFD + FYM 5t/ha + VC 2.5 t/ha resulted in significantly higher nutrient content compared to sole application of RFD and the control. Significantly higher uptake of these nutrients in both grain and straw were recorded in the treatment receiving RFD along with FYM 5 t/ha and VC 2.5 t/ha followed by 75% RFD along with FYM 5 t/ha and VC5 t/ha. The highest benefit: cost (B: C) ratio of 4.10 and 3.87 was recorded in ‘Pusa Sugandh 3’ under recommended fertility levels.
