Analysis the parameters of quality sunflower hybrid seed after processing on precleaning machine

Abstract

In the conditions of market economy and fierce market competition, a priority for oilcrops seed producers and processors is meeting the high requirements of seed quality. Production of sunflower seed, of the required quality, has to be completed in a short period of time, in order to leave sufficient time for a country-wide advertizing campaign and shipment of the entire seed production to end customers. In addition to these time constraints, seed processing has been simultaneously required to keep improving the quality of processed seed. The paper discusses the tests of several seed quality parameters (test weight, thousand seeds weight, pure seeds, germination energy and germination), for four sunflower hybrids (Duško, NS Gricko, NS-H-111, Rimi PR). The policy of the plant is to process hybrid sunflower seed in lots (a maximum weight of 20,000 kg), each lot originating from a single location. The studied period involved one production year. Quality parameters were observed per hybrids for one machine (precleaning maschine). The results of testing showed that the seed of better quality after passage through the precleaning machine, that are better seed quality parameters at the exit of the machine.

U tržišnim uslovima privređivanja i ambijentu oštre konkurencije, prioritetan zadatak proizvođača semena uljanih kultura je proizvodnja semenskog materijala koja zadovoljava visoke zahteve kvaliteta proizvoda. Proizvodnju kvalitetnog semena hibridnog suncokreta je potrebno realizovati u veoma kratkom vremenskom periodu, kako bi se na vreme marketinški pokrilo tržište i kompletna proizvodnja semena plasirala do krajnjeg kupca. Pored vremenskog ograničenja dorade, postavljeni su paralelno i zahtevi poboljšanja kvaliteta dorađenog semena. Radom su obuhvaćena ispitivanja više parametara kvaliteta (hektolitarska masa, masa 1000 semena, čistoća, energija klijanja i klijavost semena), za četiri hibrida semena suncokreta (Duško, NS Gricko, NS-H-111 i Rimi PR). Seme hibridnog suncokreta je dorađivano po partijama (max. 20.000 kg) i lokalitetima (mestima proizvodnje). Istraživanje se odnosilo na period u godini proizvodnje, za izabrane hibride. Parametri kvaliteta su posmatrani po hibridima za jednu mašinu (grubi čistač). Rezultati ispitivanja su pokazali da je seme boljeg kvaliteta posle prolaza preko grubog čistača, odnosno da su parametri kvaliteta semena bolji na izlazu iz mašine.
