A field experiment was conducted during pre-kharif season of 2016 and 2017 at Research Farm, College of Agriculture, Central Agricultural University, Imphal, Manipur, to study the effect of crop establishment methods and nitrogen management on growth and yield of rice (Oryza sativa L.). Rice cultivar CAU-R3 was grown with twelve treatment and laid out in split plot design, keeping crop establishment methods viz. C1-system of rice intensification (SRI), C2-integrated crop management (ICM) and C3-conventional as main plot with four nitrogen management viz. N1-100% recommended dose of nitrogen (RDN) through urea, N2-100% RDN through farm yard manure (FYM), N3-75% RDN through urea + 25% RDN through FYM and N4-50% RDN through urea + 50% RDN through FYM in sub-plot, replicated thrice. Studies from pooled data found out that C1 contributed the highest value of growth parameter and yield attribute as compared to C2 and C3. Among the nitrogen management N3 produces the highest growth parameter at all the stages of crop except at 30 days after transplanting than other three nitrogen management as well as highest value of yield attribute and yield. However, rice grown under ICM produces significantly higher yield than conventional method but at par with SRI.
