Abstract A field experiment was conducted during summer at High Altitude Rice Research Sub-station, SKUAST-K, Larnoo, Anantnag to study the impact of integrated nutrient management on yield and yield attributes of rice. The sixteen treatment combinations comprising of four levels of organic manure FYM (M0=0, M1=10, M2=20, M3=30 tha−1 FYM) and four levels of NPK fertilizers (F0=0: 0: 0; F1=40: 30: 20; F2=80: 60: 40; F3=120: 90: 60kg NPK ha−1) were tried on high altitude rice variety K-429 following RBD with three replications. Application of both organic manure FYM and NPK fertilizers significantly increased grain yield and otherattributes. Among different FYM levels application of M3 (FYM 30tha−1) recorded higher grain yield and straw yield, increased plant height and number of effective tillers followed by M2 (FYM 20t ha−1). Among different fertilizers doses, the NPK combination 80: 60: 40 kgha−1 (F2) recorded significantly higher grain yield and yield components as compared to lower doses (F0 and F1) but was at par with highest dose F3. Grain yield and its component were also affected significantly by the interaction between manure and fertilizer levels. Among different manorial and fertilizer dose 80: 60: 40 kg NPK ha1(M2F2) was found to be economically the best and recorded higher grain yield and other yield attributing characters and was thus recommended for high altitude rice growing areas of Kashmir.
