Abstract
Seed growing has recently become significantly
important in agriculture. Preparing the seeds to coat for plantation and using
the coated seeds for plantation has brought about new perspectives in farming.
Shape, size and one thousand seeds mass are among the most effective criteria
for the success of seed coating. In this study; cherry belle, carrot and
nigella seeds which have different sizes and shapes together with one thousand
seeds mass and seedling emergence were studied. For this purpose, a seed
coating equipment was designed, produced and analyzed through a horizontally
shaped boiler. In the designed equipment, the seeds were coated in the form of
approximately 2 mm diameter in order to pellet accordance with the ISTA norms.
As the results of the performed tests show that; cherry belle was coated %99,
nigella seed %99 and carrot seed %97. As for the seedling emergence; cherry
belle germinated %95, nigella seed %17 and carrot %75. The results of the
analysis indicate that the types of the seeds used in the test can be achieved
by pneumatic plantation machine. But the nigella seeds did not show enough
seedling emergence. It should be noted that carrots and nigella seeds aren’t
spherical. If carrots and nigella seeds are pelleted, the sphericity will
increase up to 40-60%. By pelleting seeds their physico-mechanical properties
will be more homogeneous.
