Another problem in our research has been the influence of seeding distance between rows on the level of branching in Alaska variety and Exagone hybrid, as presented in Table 4. Table 4. The influence of seeding distance between rows of plants branching rape.

In other words, the larger distance between rows (25.0 cm, 37.5 cm, and 50 cm), the higher number of ramification, the number of pods will be higher, and the production will be bigger. Influence of seeding distance between rows on the number of pods/plant, their length and number of grains in pods. An important objective of the research was the influence of seeding distance between rows on the number of pods / plant and their length. The results are presented in Tables 5, 6 and 7. The analysis of the results on the number of pods / plant highlights that the sowing distance has a great influence on the number of pods / plant, both in Alaska variety and especially in 322
