This experiment was carried out in 2012 and 2013 cropping seasons at the experimental field, Kabba College of Agriculture, Horticultural Section (Latitude 70 53 N, Longitude 60 8 E) in the Southern Guinea Savannah ecology to investigate the effects of age at transplanting on growth and tillering pattern of swampy rice [NERICA 1]. The treatments consist of six different ages at transplanting (6, 10, 14, 18, 22, and 26 days). The treatments were arranged in a Randomised Complete Block Design and replicated three times. Data were taken on agronomic traits such as plant height, leaf area, stem girth and number of tillers per plant. Yield parameters taken were number of grains per panicle, weight of grains per plant and panicle length. Data collected were subjected to analysis of variance (ANOVA) and means were separated using Duncan Multiple Range Test at 5% level of probability. The result obtained from study indicated that delayed seedlings at the nursery (22 and 26 days) were better in terms of growth parameters except in the number of tiller produced per plant. Early transplanting of seedlings at 6 and10 days was superior in grain yield. However, in all the ages considered seedlings transplanted at 10 days recorded the highest number of tillers and grain yield. It is therefore recommended that rice seedlings [NERICA 1] should be transplanted at 10 days in the study area.
