Limiting factors in sunflower seed production in 1999

Abstract

The production of seed sunflower, like any other seed production, has its own peculiarities and additional requirements that often do not appear in commercial production. First of all, one must be much more rigorous when-choosing the plot and the crop rotation must be adhered to without exception. Also, the herbicides and their doses must be decided upon carefully and the plots must be kept free of weeds all the way through until harvesting. Certain additional requirements may present themselves when carrying out the other crop tending measures as well. Of course, there is also the problem of spatial isolation to prevent contamination by unwanted pollen. Still, the largest differences between the two types of production are related to sunflower pollination. .

Proizvodnja semenskog suncokreta kao i svaka semenska proizvodnja odlikuje se odgovarajućim specifičnostima i dodatnim zahtevima koji se često ne javljaju u merkantilnoj proizvodnji. Kao prvo mora se biti rigorozniji pri izboru parcele i striktno poštovati plodored. Mora se voditi računa pri izboru herbicida kao i njihovih doza a parcele se moraju održavati čistim od korova sve do žetve. Određeni dodatni zahtevi mogu se javiti i prilikom izvođenja drugih mera nege. Naravno, tu je i problem prostorne izolacije radi sprečavanja kontaminacije nepoželjnim polenom. Ipak najveće razlike vezane su za oplodnju suncokreta.
