Analysis of Quality and Quantity of Perennial Grass Seeds in the Processing

Abstract

This paper presents an analysis of the impact of the initial purity of natural seeds of perennial grasses in the amount of processed seed in the processing process. It also determined the quality of processed seed. It is important that the difference between assessed amounts of pure seeds in laboratory is lower than the actual amount of obtained seeds in processing. In the natural seed, different amount of the variety of inert matter and seeds of weeds could be found. It is very difficult to separate it in the finishing process. The content of the pure seed, inert matter, weeds and other species in the revised seed are defined by the “Rules of the seed quality”. The six lots of perennial grasses seeds of different purity were processed. There were three lots of meadow fescue, two lots of tall fescue and one lot of cocksfoot. Quantity of processed seed, losses of seeds and processing output was determined at the end of the seed processing.

U radu je prikazana analiza uticaja početne čistoće naturalnog semena višegodišnjih trava na količinu dorađenog semena pri procesu dorade. Takođe je određen kvalitet dorađenog semena. Pri procesu dorade semena višegodišnjih trava važno je da razlika između količine čistog semena koja se laboratorijski proceni pri prijemu semena i stvarne količine dobijenog semena u pogonu za doradu bude što manja. U naturalnom semenu se nalaze korovi i inertne materije koji se veoma teško odvajaju pri doradi. Pravilnikom o kvalitetu semena definisan je sadržaj čistog semena, inertnih materija, korova i drugih vrsta u dorađenom semenu. Dorađivano je šest partija naturalnog semena višegodišnjih trava različitih čistoća. Tri partije livadskog vijuka, dve partije visokog vijuka i jedna partija ježevice. Na kraju procesa dorade određena je količina dorađenog semena, gubici semena i randman dorade.
