SOWING SCOTS PINE SEED WITH A MODIFIED SINGLE-SEED SEEDER UNDER CONTROLLED CONDITIONS

Józef Walczyk, Paweł Tylek

 

ABSTRACT



A tool carrier was designed for work in closed spaces. A sowing section of the seeder was modified, which permitted sowing of Scots pine seed in rows, 0.05 m wide. Modification of the sowing assembly also permitted to sow two rows during a single passage of the section, and this increased efficiency of sowing. Results of this study showed that the designed unit can be used for sowing under controlled conditions. Apart from better distribution of seedlings in comparison with hand sowing, a 35 % seed saving was obtained.

Key words: single-seed sowing, seed sorting..
