Abstract
Glyphosate and paraquat were evaluated as substitutes for hoe-tillage in the preparation of seedbeds for sorghum and pearl millet. The herbicides were applied at 0.5, 1 and 2 kg/ha, during the period between weed and crop emergence. All treatments except 0.5 kg/ha of paraquat gave acceptable yields. Glyphosate applied at 0.5 kg/ha and paraquat at 1 or 2 kg/ha, gave similar crop yields. Sorghum grain yield after treatment with 1 kg/ha of glyphosate was not significantly different from that obtained in hoe-tilled fields. The addition of atrazine at 0.5 kg/ha to some treatments did not improve crop yield or weed control.ADDITIONAL ABSTRACT:Tests were made in sorghum and millet fields with glyphosate and paraquat applied at rates of 0.5, 1.0 and 2.0 kg a.i./ha, in the period between weed and crop emergence. All treatments except 0.5 kg a.i./ha of paraquat gave acceptable yields. Glyphosate applied at a rate of 0.5 kg a.i./ha and paraquat at 1.0 or 2.0 kg a.i./ha gave similar yields. Sorghum grain yield after treatment with 1.0 kg a.i./ha of glyphosate was not significantly different from that obtained in hoe-tilled fields
