Abstract

Field experiments were conducted at Sugarcane Research Station, Cuddalore, Tamil Nadu during 1995-96 and 1996-97, to integrate tillage and herbicides to control weeds with special reference to Cyperus rotundus in sugarcane. The results revealed that the preplant application of glyphosate @ 2 kg ha'' (with 2% ammonium sulphate)plus three disc harrowings followed by pre-emergence application of atrazine 1 kg or alachlor 1.5 kg ha+hand weeding at 60 DAP recorded 92% weed control efficiency and increased the cane population (50%), cane yield (91%) and sugar yield (86.6%) over farmers method of three disc harrowings and hand weeding twice at 30 and 60 DAP.

8 of 13 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.

Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
