Abstract: In a field macro experiment which has been carried out in locality of “Bosevica” on alluvial soil type has been investigated weed vegetation with rice grown in precrop of some fodder plants (a mixed forage crop). The variants in the experiments were the following: I – precrop of forage pea (Pisum sativum ssp. arvense L.), II - for-age pea (Pisum sativum ssp. arvense L.) + wheat (Triticum aestivum L. cultivar “babuna”), III – chickling (Vicia vilosa L.) and IV-control (continuous cropping sistem). According to the obtained results it has been ascertained that the average number of weeds per m^2 of Echinchloa spp., Heteranthera limosa (Sw) Wild and Leersia orizoides in variants I, II and III significantly decreased compared to the control, where as that of Cyperus spp. and Scirpus maritimus is bigger. Weed density compared to control (100%) has reduced for 48,3% in variant II and 47,1 % in variant III (an exception is variant I which, has increased for 16,0%). In variants I and II dominant weed species is Scirpus maritimus (421,3 and 91,3 plants per m2, respectively), in variant III, Cyperus spp. (88,0 plants per m^2) and in control Echinchloa spp. (205,3 plants per m2). The highest average grain yield of paddy rice is achieved in variant II (8.380 kg/ha) and the lowest one in control (4.500 kg·ha-1).
