Sowing quality means required vertical (depth) and horizontal (spatial) spacing of seeds in the soil with minimal damage to the seeds. The spatial distribution of seeds (horizontal spacing) is given by distance between the rows and spacing of the seeds in a row. The objective of the study was the evaluation and comparison of the sowing quality of sowing machine jd maxemerge xp with mechanical filling of ladle holes with holding fingers within usage of seeds with different dimensional and shape attributes in agricultural conditions. Sowing machine jd maxemerge xp reached good results for the quality especially when using the angular seeds. It reached the sowing quality expressed by the standard deviation of 46.95 – 50.76 % when seeds pr 37 n01 and for seeds pr 37 n01 it is 47.43 – 48.73 %. Another evaluative criterion is dual sowing of seeds or plants (drr), it was reached the average value 3.65 – 2.45 % for angular seeds and the average of 1.54 – 3.71 % for approximately spherical seeds.
