In Hungary the spring time sowing of maize and sunflower is very critical, as the optimal time window is short. The soil moisture decreases rapidly, and the unstable weather conditions create even more difficult conditions for the farmers, but the sowing quality and the plant density have strong effects on the yield. In our experiments we explored the possibility of speeding up the process of sowing, as a solution to this problem, and found that compared to the baseline, the increased speed caused perceptible quality problems, and density loss. These problems may lead to serious yield and economical loss, so the increased sowing speed is not an advisable option.
