Abstract: Information is given on the crop and the weed control treatments tested. Control effectiveness of the selected treatments, i.e. alachlor, atrazine, cyanazine, methazole, paraquat, handhoeing, inter-row rotavating and spiral plowing are discussed. Except for cyanazine and paraquat, the experimental results are summarized with regard to seedling emergence, flowering, number of ears per plant, grain yield and N-content of the grains. Alachlor pre-em. had a depressive effect on seedling emergence, whereas a lower N content of the grains was recorded after preem. use of atrazine. The remaining effects of the weed control treatments on the crop were not statistically significant at the 5% level. The damage symptoms encountered are described. Eventually the labour requirements are given for hand-hoeing, inter-row rotavating, spiral plowing and spraying.
