Afficher plus [+] Moins [-]Field experiments were conducted under rainfed conditions during the 1987 and 1988 kharif season on pearl millet (Pennisetum glaucum (L) R. Br) to test the comparative efficacy of pre-emergence herbicides atrazine and terbutryne applied separately, in mixture and in combination, with hand-hoeing. Weed density and dry weight significantly reduced by herbicide application and hand-hoeing. Atrazine or terbutryne alone at 1.0 kg a.i./ha or in combination at 0.5 kg a.i./ha each, resulted in mortality of pearl millet plants. Pre-emergence application of atrazine at 0.5 kg a.i./ha followed by hand-hoeing at 30 days after sowing gave effective weed control, and resulted in more grain yield compared to the unweeded-control
