Impact of speed sowing mashine "PSK-4" on the distribution of seed per surface and depth

U radu su objašnjeni principi i metode uzgoja kukuruza. Opisuju se svi radni zahvati, prije i nakon sjetve kukuruza. U radu je najviše objašnjen princip rada ispitivane sijačice OLT PSK-4. Kroz cijeli rad istražuju se važniji pokazatelji OLT PSK-4 sijačice. Opisani su svi radni dijelovi sijačice OLT PSK-4 te njihov princip rada. Kako bi se što bolje shvatio i istražio rad sijačice OLT PSK-4 obavljeno je kronometriranje u sjetvi kukuruza. U radu su također detaljno opisane metode sjetve te svih pokusa koji su obavljeni u istraživanju.This paper presents and explains the principles and methods for growing corn. All work is described, before and after sowing of corn. Particular attention is focused on sowing and sowing machine – corn sage. Troughout the paper there is a talk about sowing machine OLT PSK-4. All working parts of sowing machine OLT PSK-4 are described including their working principle. In order to understand and investigate the work of the sowing machne OLT PSK-4 we performed a chronometry. The paper also describes the methods of sage and which are done in research
