As you can see in our pictures, seeds are smaller this year, so we had to change the dishes. New dishes have 10 holes of 12x6mm (old dishes have 10 holes too but of 14x7mm). Sowing is the same with these dishes: we have same speed, same distance between rows (it is 72cm) and same distance between seeds(it is 26cm); if we change bigger sprockets we can get a distance between seeds of 30cm. We avoid sowing two seeds together with these dishes.
We use a JJ Broch mechanical sower with four rows. In my area, it is the most common mechanism and it really works very fine. We used 3kg of seeds per hectare.
About seeds, they are a hybrid of Arlesa company. It is called Almanzor and we have always got good crops with this type of seeds.
