Higher sowing densities (57,100, 71,400 and 85,500 plants/ha) of the female component did not significantly affect the yield increase in the hybrid ZP 196 (4.56, 4.61 and 4.70 t/ha) under natural conditions of cultivation, but they significantly affected the increase of the number of germinated seeds (21,272,000, 23,893,000 and 24,226,000/ha). In the seed production under irrigation conditions of the hybrid ZP 677, greater densities (71,400, 85,500 and 99,900 plants/ha) did not significantly affect the increase of neither the yield (3.39, 3.44 and 3.60 t/ha) nor the number of germinated seeds (11,238,000, 11,651,000 and 12,427,000/ha). On the other hand, higher sowing densities (71,000, 85,500 and 99,900 plants/ha) of the female component significantly increased both, the yield (4.01, 4.38 and 4.40 t/ha) and the number of germinated seeds (13,122,000, 15,022,000 and 15,560,000/ha) in the hybrid ZP 680 under irrigation conditions.
