RESEARCHING MECHANICAL AND PNEUMATIC SOWING-DEVICE AS SOWING THE SEED OF SOYBEAN

Abstract

In this article the results are illustrated of researching in condition of field and laboratory for sowing the seed of soybean by sowing-machine SCHX-4 and its mechanical sowing device as well precision sowing-machine Sonmezler and its pneumatic sowing devices. During researches, the difference of sowing measures by SCHX-4 which has mechanical sowing apparatus from real sowing measures made-up 6,75 %, average sowing deepness and its average square declination made-up 3,8 and 0,31 cm respectively, the wideness between main and side rows constituted 89,5 and 92,5 cm correspondingly, the damaging level of seed was 5,2 % by seeder SCHX-4 which has mechanical sowing apparatus, it was defined that, it does not answer for agro technical requirement and then the restrictor was installed that made from rubber and formed as half moon form on the hole where the seed goes down of sowing apparatus, so that decreasing opportunity damaging of seed to 0,8 % was based. Also, during the researches, it was defined that for providing high sowing measures by pneumatic seeders (400–500 thousand pieces/ha) it is suggested to adapt sowing apparatus for dual-rows.
