Abstract
The field experiment was conducted in the Experimental Farm, Department of Agronomy, Faculty of Agriculture, Annamalai University, Annamalai Nagar, Tamil Nadu during June-September 2023 to study the effect of weed management on yield attributes and yield inpearl millet. There are eleven weed management treatments viz., T1 - Atrazine 0.5 kg ha-1 (Pre), T2 -Pendimethalin 0.75 kg ha-1 (Pre), T3 - Pretilachlor 0.45 kg ha-1 (Pre), T4 - Atrazine 0.5 kg ha-1 (Pre) + 2, 4-D0.5 kg ha-1 (PoE), T5 -Pendimethalin 0.75 kg ha-1 (Pre) + 2, 4-D0.5 kg ha-1 (PoE), T6 - Pretilachlor 0.45 kg ha-1 (Pre) + 2, 4-D0.5 kg ha-1 (PoE), T7 - Atrazine 0.5 kg ha-1 (Pre) + Tembotrione 0.08 kg ha-1 (PoE), T8 - Pendimethalin 0.75 kg ha-1 (Pre) + Tembotrione 0.08 kgha -1 (PoE), T9 - Pretilachlor 0.45 kg ha-1 (Pre) + Tembotrione 0.08 kg ha-1 (PoE), T10 - Two hand weeding at 15 and 30 DAS and T11 - Unweeded Control were laid out in randomized block design with three replications. Among the herbicide treatments, Pendimethalin 0.75 kg ha-1 (Pre) + Tembotrione 0.08 kg ha-1 (PoE) (T8)recorded the higher yield attributes and yield of pearl millet viz., number of tillers plant-1 (5.09), ear head length (29.95 cm), ear head girth (11.49 cm), number of grains earhead-1 (2294), thousand grain weight (10.47g), grain yield (3347 kg ha-1) and stover yield (5155 kg ha-1). The least values of yield attributes, grain and stover yield of pearl millet was recorded under the unweeded control (T11).
