The present investigation was conducted with the objective to know the effect of integrated nutrient management and plant geometry on growth and yield attributes of rice varieties during Kharif season of 2015 and 2016. The study comprised six treatments of integrated nutrient management (F0: Control, F1: RDF (120:60:60) F2: 50% RDF + 50% Vermicompost, F3: 75% RDF + 25% N through Vermicompost, F4: 50% RDF + 50% N through FYM F5: 75% RDF + 25% N through FYM) with two varieties namely NDR-359 and Sarju 52 and two plant geometry (a) S1: 20 cm × 20 cm. (b) S2: 30 cm × 30 cm. the present investigation showed that the growth attributes were significantly influence due to different combination of organic and inorganic nutrients, varieties and plant geometry during both the years and in pooled analysis. The growth attributes viz., plant height (cm), number of shoots (m-2), dry matter accumulation (g m-2) at 30, 60, 90 DAT and at harvest and leaf area index at 30, 60 and 90 DAT were recorded significantly higher with the application of integrated nutrient management treatment F2 (50% RDF + 50% N through vermicompost). The variety V1 (NDR-359) and plant geometry S1 (20 cm × 20 cm) were recorded significantly higher growth attributes viz., plant height (cm), number of shoots (m-2), dry matter accumulation and leaf area index under SRI technique during both the year and in pooled analysis. The quality attributes like hulling % and protein content in grain were recorded in INM treatment F2, variety V1 and plant geometry S1 during both the years and in pooled analysis.
