Effectiveness of some herbicides in sugar beet crop in the production conditions of 2020 and 2021
Tokom 2020. i 2021. godine ispitivana je efikasnost herbicida za suzbijanje Å”irokolisnih korova u usevu Å”eÄerne repe na podruÄju Južnog Banata. Ispitivane su varijante sa kombinacijom sledeÄih aktivnih materija: metamitron, etofumesat, fenmedifan, trisulfuron-metil, klopiralid i lenacil. Herbicidi su primenjeni u tri split tretmana u razmaku od 10 do 20 dana, tretiranjem korova u osetljivoj fazi (kotiledoni i prvi par stalnih listova). U ogledu su bile zastupljene sledeÄe korovske vrste Chenopodium album, Sttachys annua, Solanum nigrum, Euphorbia cyparissias, Polygonum aviculare, Ambrosia artemisiifolia, Datura stramonium, Cirsium arvense, i Abutilon theophrasti. Rezultati ispitivanja su pokazali da je Ch. album u obe godine ispitivanja pokazao nisku osetljivost prema svim ispitivanim varijantama osim kombinacije metamitron, etofumesat, lenacil, trisulfuron metil koja je ispoljila maksimalnu efikasnost kako prema ovom korovu tako i prema ostalim korovskim vrstama. Dobijeni rezultati potvrÄuju efikasnost dostupnih herbicida na tržiÅ”tu, nakon povlaÄenja iz upotrebe do sada koriÅ”Äenih aktivnih materija.In 2020 and 2021 field trials were carried out to evaluate efficacy herbicides (three and four active substances) for controlling broadleaf weeds in sugar beet crop, in the South Banat region. Treatmans with a combination of the following active substances were tested: metamitron, ethofumesate, fenmedifam, triflusulfuron-methyl,clopyralid, lenacil. Herbicides were applied in three treatments with an interval of 10 to 20 days depending on depending on weather conditions and the appearance of weed plants that were treated in a sensitive phase (cotyledons and the first pair of permanent leaves). The following types of weeds were represented in the experiment Chenopodium album, Sttachys annua, Solanum nigrum, Euphorbia cyparissias, Polygonum aviculare, Ambrosia artemisiifolia, Datura stramonium, Cirsium arvense, Abutilon theophrasti. The results suggest that Ch. album in both years of testing showed low susceptibility to all tested variants, except for the combination of metamitron, etofumesate, lenacil, trisulfuron methyl, which showed maximum efficiency both against this weed and against other weed species. The obtained results confirm that even with the loss of the license for the registration of some active substances, there are effective combinations of herbicides that can successfully keep the sugar beet crop free from weeds

Evaluation of salinity stress tolerance in various wheat genotypes
U cilju procene tolerantnosti pŔenice na stres saliniteta, sproveden je
dvogodiŔnji ogled sa 27 genotipova pŔenice, gajenih na dva lokaliteta:
Kumane (solonjec, poveÄana zaslanjenost) i Rimski Å anÄevi (Äernozem,
kontrola). Stres zaslanjenosti je uticao na smanjenje prinosa zrna po klasu
za oko 30%, Å”to ovu osobinu Äini dobrim fenotipskim markerom uticaja
stresa zaslanjenosti na razvoj pŔenice. Selekcija zasnovana na
vrednostima indikatora SP, ITS i IP favorizuje odabir genotipova Bankut
1205, OraŔanka, KG-58, Jugoslavija, Renesansa i Harmonija. Iz grupe
genotipova sa visokim vrednostima SP, ITS i IP (klaster A), genotip
Harmonija ima nisku vrednost parametra IOS (0,52) i visoke vrednosti
ISP (0,84), IP (1,66) i prinosa zrna po klasu na solonjecu (1,50 g), Ŕto ga
Äini veoma tolerantnim genotipom na salinitet. Parametri IOS i ISP
identifikuju genotipove koji se, bez obzira na nizak prinos, odlikuju
malom osetljivoÅ”Äu na stres (Å umadija, Rujna i Premija), zbog Äega mogu
biti koristan genetiÄki resurs u oplemenjivaÄkim programima.In order to assess the tolerance of wheat to salinity stress, a two-year
trial was conducted with 27 wheat genotypes, grown on two soil types:
Solonetz (salinity stress) and Chernozem (control). Salinity stress reduced
grain yield per ear by about 30%, which makes this trait a good
phenotypic marker of salinity stress. Selection based on SP, ITS and IP
indicators favors the selection of genotypes Bankut 1205, OraŔanka, KG-
58, Jugoslavija, Renesansa, and Harmonija. From the group of genotypes
with high values of SP, ITS and IP, the genotype Harmonija has a low
value of the parameter IOS (0.52) and a high value of ISP (0.84), IP
(1.66), and grain yield per ear on the Solonetz (1.50 g), which makes it
salinity-tolerant genotype. The parameters IOS and ISP identify
genotypes that, regardless of low yield, are characterized by low
sensitivity to stress (Å umadija, Rujna, and Premija), because these
genotypes could be a useful genetic resource in breeding program
