N2  - Performance of lowland rice grown on anaerobic wetland soil is greatly affected by iron toxicity disorder in Nigeria. Better nutrient management and cultivation of resistant varieties have been recommended as strategy to manage this nutrient disorder. Information on intraspecific lowland NERICA cultivars grown on iron toxic soil augmented with compost is scanty. Therefore, the effect of different rates of compost on growth, dry matter and grain yield of lowland NERICA cultivars grown on iron toxic soil was investigated. A greenhouse experiment comprising of three (two NERICAs and ITA  212)  lowland  rice  cultivars  and  four  varying  rates  of  compost  arranged  in  completely randomized  design  with  six  replicates  was  conducted  in  greenhouse  of  Botany  Department, University of Ibadan. Data collected on growth and yield parameters were analysed using ANOVA and LSD at P≤ 0.05. Correlation and simple linear regression were used to establish relationship between growth and iron toxicity scores. Results showed that iron toxicity significantly (p≤0.05) reduced  growth  and  yield  of  lowland  rice.  Growth  and  grain  yield  of  NERICA  cultivars  were significantly  better  (P  ≤0.05)  on  soil  augmented  with  compost  than  control.  Grain  yield  was significantly related to the number of leaves affected by iron toxicity. Cultivating lowland NERICA-L-1 on iron toxic soil augmented with 8t ha -1 of compost will enhance better growth, dry matter characteristics and increase lowland NERICA grain yield.
