This paper presents some experimental results to determine the incidence of mechanized sowing speed in the development and growth of rice in El Espinal-Tolima. Using a completely randomized design and a seed density of 104.5 ± 3.3 kg/ha, plots were sown in three replicates at 3.31 ± 0.05 km/h, 5.13 ± 0.18 Km/h, and 6.98 ± 0.24 km/h. Plant population, plant weight, dry matter, moisture content, and yield showed statistically significant differences with respect to sowing speed. This research found that the sowing speed has a proportional relationship with: a) the percentage of plants grouped in their roots, b) the number of non-productive tillers, c) the fuel consumed rate, d) uncovered seed, e) effective field capacity. The sowing speed of 5.13 ± 0.18 km/h was achieved by plants with a higher number of panicles per m2 and yield: this is optimal.
