Volume dosing of seeds by sowing apparatuses of seed drills satisfies the criteria of preciseness of the total norm and of steadiness of seed flow in the function of moving speed of sowing combination. Central sowing apparatuses with pneumatic transport and division to depositors achieves a high variation coefficient in the transvesal distribution. It is specially expressed at sowing of larger seeds of bigger mass of the individual grain. The coefficient of variation increases by increasing of number of distributing heads in the line of seed transportation. Longitudinal distribution is according to exponential curve in all types of sowing apparatuses with volume dosing. The improvements of sowing apparatuses are directed towards elimination of the shortcomings mentioned.
