The effect of spacing on growth, yield and yield components of bambara groundnut cv. Songkhla 1 was conducted at the Agronomy Practice Station, Faculty of Agricultural Technology, Songkhla Rajabhat University, Khao Roob Chang subdistrict, Muang district, Songkhla province, during November 2017 to February 2018. Randomized complete block design (RCBD) with 4 replications was used as an experimental design. Treatments consisted of 4 planting spaces: 60×30, 60 × 40, 60 × 50 and 60 × 60 cm. The results showed that planting spaces had no significant effect on field emergence, time to 50 % of emergence, time to 50 % of flowering, plant height, canopy diameter and number of seeds per pod. Plant spacing at 60 × 40, 60 × 50 and 60 × 60 cm gave high petiole numbers (54.40-65.28 petioles/plant). The bambara groundnut planted with 60 × 30 and 60 × 40 cm spacing produced the highest fresh pod yield (383.00-415.50 kg/rai). The planted with 60 × 40 cm spacing gave higher yield components than those with 60 × 30 cm spacing; 14.38 mm width seed, 21.32 mm length seed, and weight of 107.50 g/100 seeds. Thus, 60 × 40 cm spacing is recommended for the cultivating of Bambara groundnut cv. Songkhla 1 that gave high yield and yield components.
