Abstract
A field experiment was conducted at the Indian Institute of Sugarcane Research, Luchnow, under subtropical Indian conditions during the season 2012-2013 to study the evaluation of phytotoxicity of sulfantrazone 48% f to sugarcane variety CoSe 92423. The experimental design was Randomized Complete Block Design (RCBD) with four replications. The treatments used in the experiment are sulfentrazone PPI 720 g a.i.ha-1, sulfentrazone PPI 1440 g a.i.ha-1, sulfentrazone Pre-em: 3 DAP 720 g a.i.ha-1, sulfentrazone Pre-em: 3 DAP 1440 g a.i.ha-1 and untreated control(weedy). The results showed that sulfentrazone PPI 1440 g ai.ha-1 registered the highest increase of germination (56.9 %) that didn’t differ significantly from other treatments. The dry matter accumulation in weeds was the lowest (7.2, 10.6 and 22.8 g.m-²) in sulfentrazone PPI 1440 a.i.ha-1 treatment achieved highest inhibition proportion of dry matter (90.2, 88.9 and 83.5 % ) at the 60, 90 and 120 DAP respectively. Phytotoxicity was not significantly affected by use of sulfentrazone herbicide. a significant increase in average number of canes by using sulfentrazone PPI 1440 g a.i.ha-1 led to even the highest increase in this attribute at the 90,120,150, 210 and 300 DAP. The use of sulfentrazone PPI 1440 g a.i.ha-1 registered the highest cane yield (84.1 t.ha-1) that was significantly higher to the tune of 44.94 % over control. Addition of sulfentrazone treatments significantly affected sugar yield. Sulfentrazone PPI 1440 g a.i.ha-1 and sulfentrazone Pre-eme 1440 g a.i.ha-1caused highest increase in this character which reached to 13.850 and 13.500 t.ha-1respectively.
