Abstract (croatian)

Sivi muhar (Setaria glauca L. P. Beauv.) uskolisna je korovna vrsta koja se redovito javlja u svim okopavinskim usjevima Hrvatske. Uspješnost ove vrste ogleda se u brzu plodonošenju, velikoj produkciji i dugovječnosti sjemena. Sivi muhar kozmopolit je u područjima umjerenog pojasa s arealom rasprostranjenosti između 55° sjeverne pa sve do 45° južne geografske širine. Sposoban je prilagoditi se različitim klimatskim uvjetima, pa u toplijim klimatima razvija veći, a u hladnijim klimatima manji biološki minimum (Tb). Za područje kontinentalne Hrvatske (Šašinovec) Tb iznosi 6,6 °C, a biološki vodni potencijal (Ψb) iznosi ‐0,71 MPa. Teže podnosi vodni stres, pa se javlja u godinama i područjima s većom količinom padalina. Sivi muhar niče iz plitkog sloja tla, odnosno iz dubine 1 – 5 cm. Odgovaraju mu različiti tipovi tala s pH vrijednošću od 6,1 do 8,0. Kao korovna vrsta na poljoprivrednim površinama Setaria glauca može uspostaviti veliku gustoću po jedinici površine i time uvelike utjecati na prinos poljoprivrednih kultura. Osim direktnih šteta, i indirektno šteti jer se povećavaju troškovi čišćenja uroda, a može biti i alternativni domaćin patogena, uzročnika bolesti usjeva.

Abstract (english)

Yellow foxtail (Setaria glauca L.) is a narrow‐leaved weed species that occurs regularly in all row crops in continental Croatia. The success of this species may be attributed to rapid fruiting, large production of seeds and their longevity. This species is cosmopolitan in temperate zones with an area of distribution ranging from 55 °N to 45 °S latitude. It is able to adapt to different climatic conditions, so in warmer climates it develops higher, while in colder climate lower biological minimum (Tb). For the area of continental Croatia (Šašinovec) estimated Tb is 6.6 ° C, while biological water potential (Ψb) is ‐0.71 MPa. Yellow foxtail hardly tolerates water stress which is why it occurs in years and areas with higher rainfall. This species grows from a shallow layer of soil, ie
from a depth of 1 ‐ 5 cm. It grows on different soil types with a pH of 6.1 to 8.0. As a weed species on agricultural land, Setaria glauca can establish a high density per unit area and thus greatly reduce the yield of cultivated crops. In addition to direct damage, this species is also responsible for increasing cleaning costs and may be an alternative host to crop diseases.
