A Jubilee In 1977 at the Faculty of Agriculture in Sarajevo he founded the first postgraduate study in weed science with teachers from Yugoslavia, Switzerland, Italy, etc. He presented numerous papers with results of his research at Symposia and Congresses held in Uppsala, Moscow, Warshaw, Leipzig, Brno, Bratislava, Keszhtely (Hungary), Poznan, Brighton, Gent, Sydney, etc. He was chairperson at the EWRS Symposia in Uppsala, Paris and Lisbon. As a guest of the Indian Government he delivered the invited introductory lecture on the methods of promotion of field crop production on the 63 rd Indian Science Congress, Section for Agriculture, in Vishakhapatnam in 1976. After that, he lectured at graduate studies at Agricultural Universities in New Delhi, Hyderabad and Bangalore. He was a foreign peer-reviewer of several Ph.D. thesis at foreign universities and in electing full professors at them. For his rich scientific opus and prolific profesional publications Prof. Saric was conferred the State Award „Veselin Maslesa“. He was twice nominated a laureate of the World Food Prize (known informally as the Nobel Prize for Food and Agriculture). He is a member of the Academy of Sciences and Arts of Bosnia and Herzegovina. Contribution to weed science In the course of 50 years, Professor Saric greatly contributed to weed science through his research, his numerous publications (papers and books) and through educating many generations of undergraduate, postgraduate and doctoral students. His research was particularly devoted to spreading of new, invasive weed species, various ways of weed control, herbicide testing and application, and cropweed allelopathy. In studying the weed flora of Bosnia and Herzegovina he continued the research started by Komsa and Vaskovic in the first decades of the 20th century. He pioneered the introduction of herbicides in Bosnia. He was one of the pioneers of weed science in Yugoslavia. He took part in founding and work of the EWRS. He was among the organizers of the most of national and international Weed Symposia and Congresses held in Yugoslavia. His great knowledge and very rich experience Prof. Saric has all the time readily transfered to us, his students and coworkers, to other agronomists, and to farmers. He will for long time remain an unparalleled coryphaeus of our weed science, as well as the science of soil management and agroecology. Prof. S. Muminovic 2

RESULTS OF WEED CONTROL IN FIELD POTATOES Vlad Dragoslav Mircov 1 , Ivica ðalović 2 , Zoran Brocić 3 1 University of Agricultural Sciences and Veterinary Medicine of Banat – Timisoara, Romania 2 Faculty of Agronomy – Cacak, Serbia and Montenegro 3 Faculty of Agriculturae, Belgrade – Zemun, Serbia and Montenegro Abstract Weed competition can reduce yield and potato quality, affecting tuber size, weight, and quantity. In this research paper it was compared the efficacy of 10 herbicide treatments for controlling prostrate pigweed, kochia, and Russian thistle in a low organic coarse–textured soil and to determine their effect on marketable potato yields. Study results emphasize the need for good weed control for optimum potato yields. Metribuzin applied alone or in combination with metolachlor, pendimethalin, or trifluralin plus EPTC gave excellent broadleaf weed control and the highest marketable potato yields. Key words: weeds, weed control, field potatoes. Introduction Weed competition can reduce yield (VanGessel and Renner, 1990) and potato quality (VanGessel and Renner, 1990), affecting tuber size, weight, and quantity (Nelson and Thoreson, 1981; Wall and Friesen, 1990a, Rosales– Robles et. al., 1999). Weeds interfere with harvest, causing more potatoes to be left in the field and increasing mechanical injury (VanGessel and Renner, 1990). If a mixed population of annual weeds is allowed to compete with potatoes all season, each 10% increase in dry weed biomass causes a 12% decrease in tuber yield. One redroot pigweed (Amaranthus retroflexus L.) or barnyardgrass [Echinochloa crus–galli (L.) Beauv.] per meter of row reduced marketable tuber yield 19 to 33% (VanGessel and Renner, 1990; Baziramakenga and Leroux, 1998). The critical period for weed removal in potatoes is about 4 to 6 weeks after planting. Weeds emerging 4 weeks after planting are suppressed by crop growth (Thakral et. al., 1989). These weeds may not reduce tuber yield through competition, but can interfere with harvest operations. Mechanical cultivation does not remove weeds within the row and may damage potato plants and reduce yields (Nelson and Giles, 1989). Herbicides can reduce the number of cultivations required and enhance weed control particularly during the early season before hilling. Many herbicides are
