The study was conducted Mirab Badawacho of Centeral Ethiopia. This study evaluated the effects of different plant spacing treatments (25 cm, 30 cm, and 35 cm) on the marketable yield (MY), unmarketable yield (UMY), and total yield (TY) of a given tomato Roma VF variety crop. To achieve the objective three treatments were arranged in randomized complete block design with five replications under furrow irrigation method. The highest marketable yield (21.55 t/ha) and total yield (28.47 t/ha) were recorded at the 25 cm spacing (T₁), while the highest unmarketable yield (8.2 t/ha) was observed at the 30 cm spacing (T₂). Statistical analysis showed no significant differences (ns) at the 5% level for all yield parameters. These findings suggest that closer spacing may lead to slightly higher yields, although differences are not statistically significant. The population number under 25cm spacing was higher than 30cm and 35cm spacing. The size of the fruit under 35cm spacing is better than 25cm and 30cm spacing. Therefore, in area where land resource is sufficient 35 cm spacing is recommended to obtain equivalent yield with large fruit size, but in land scarce area 25cm spacing is recommended to obtain optimum yield.
