Sowing small cereal grains in narrow rows increases productivity of grains by reducing the amount of seeds, fertilizers and herbicides, although yields do not increase. This agriculture system increases plants performance by increasing the amount of productive tillers per plant, the amount of seeds per spike, and seed weight. It is possible to use a seed density of 40-60 kg/ha, and a fertilizer doses of 120-80-40. Even water is used by plants efficiently. The experiment had four treatments: 60, 80, 100 and 120 kg of seeds per hectare. A fertilizer doses of 120-80-40 was apply to all treatments. 100 and 120 kg/ha seed doses were sown without rows, using a seeder for small grains. 60 and 80 kg/ha seed doses were sown into 25 cm narrow rows. Second fertilizer application was introduced into the soil using a till. Plants from the 60 kg/ha had the same yield that the others treatments.
