This study evaluated the influence of plant spacing and varietal selection on the growth, yield, and productivity of rice (Oryza sativa L.) under contrasting agro-ecological conditions of Jalingo and Karim Lamido, Taraba State, Nigeria. The experiment was conducted during the 2025 cropping season using a Randomized Complete Block Design (RCBD) in a 3 × 4 factorial arrangement with three replications. Treatments comprised three plant spacings (20 × 20, 25 × 25, and 30 × 30 cm) and four rice varieties (ITA 150, FARO 44, ABARE, and JAMILA). Data were collected on growth, yield, and yield-related traits and analysed using ANOVA, with means separated using Duncan’s Multiple Range Test at 5% probability. Variety, spacing, location, and their interactions significantly (P ≤ 0.05) affected most traits. ITA 150 consistently produced the tallest plants, largest leaf area, highest tiller number, longest panicles, heaviest 1000-seed weight (36.70 g), and highest grain yield (3,970 kg ha⁻¹). The 30 × 30 cm spacing produced the highest mean grain yield (3,895 kg ha⁻¹). Karim Lamido recorded higher mean grain yield (3,645 kg ha⁻¹) than Jalingo (3,115 kg ha⁻¹). The ITA 150 × 30 × 30 cm combination performed best across locations. ITA 150 at 30 × 30 cm is recommended for improved rice productivity in similar environments.
