(Herbološko društvo Srbije, 2008)
Relations (interactions) between plants can be favourable, adverse or neutral. Competition is the most widespread form of adverse interaction in agrophytocoenoses. One generally accepted definition of competition is: 'Mutual ...
Weed suppression in maize seed production: Effects of post-emergence herbicides / Suzbijanje korova u semenskoj proizvodnji kukuruza - efekti primene herbicida u toku vegetacije
(Herbološko društvo Srbije, 2008)
Widespread distribution of weeds in seed maize crops has resulted in frequent application of postemergence herbicides. Herbicides used in hybrid crops are also used in maize seed production, including sulphonylurea herbicides ...

(Društvo genetičara Srbije, Beograd, 2008)
Rhizobium leguminosarum bv. trifolii is microsymbiont Trifolium pratense and Trifolium repens, which are very important legumes in Serbia. The natural nodulating population of those bacteria was collected and estimated ...
Phenotypic characterization and relatedness of maize inbred lines / Fenotipska karakterizacija i srodnost linija kukuruza
(Društvo genetičara Srbije, Beograd, 2008)
Clear description of maze is useful in planning crosses for hybrids, in classifying inbreds to heterotic groups, and in the plant variety protection. The objection to visual assessment of morphological traits is its ...
The effect of plant arrangement pattern and hybrids on weediness of a maize and soybean intercropping system / Uticaj prostornog rasporeda i hibrida na zakorovljenost združenog useva kukuruza i soje
(Herbološko društvo Srbije, 2008)
Decrease in the number and biomass of weeds, especially of perennial ones, is one of the advantages of intercropping. The results obtained in the first two years of investigation (2003 and 2004) show that the number of ...
Effects of maize seed treatments with imidacloprid and thiametoxam on the plant spacing and grain yield / Efekat tretiranja semena kukuruza imidaklopridom i tiametoksamom na sklop biljaka i prinos zrna
(Institut PKB Agroekonomik, Padinska skela, 2008)
The abundance of pests and the rate of plant damages are controlled by the maize seed treatments with insecticides, as a preventive measure and a measure leading towards the lower population. It is expected that insecticides ...
