Three pre emergence herbicides viz.,, atrazine at 500 g ha-1, atrazine at 750 g ha-1 and pendimethalin at 1000 g ha-1, one pre-emergence herbicides mixture viz., atrazine + pendimethalin at (0.4+0.75 kg/ha), four post-emergence herbicides viz.,, atrazine at 0.5 kg/ha application at 10-14 DAS, atrazine at 0.75 kg/ha at 10-14 DAS, tembotrione (Laudis) at 80g/ha at 2-4 leaf/10-15 DAS and tembotrione (Laudis) at 100g/ha (POST) at 2-4 leaf/10-15 DAS, two preemergence herbicides with one hand weeding viz.,, atrazine at 0.4 kg/ha + one HW at 21 DAS and pendimethalin at 0.75 kg/ha + one HW at 21 DAS, one pre-emergence herbicides mixture with one hand weeding viz., atrazine + pendimethalin at (0.4+0.75 kg/ha) + one HW, three post-emergence herbicides with one hand weeding viz. atrazine at 0.4 kg/ha (POST) at 10-14 DAS + one HW at 30 DAS, tembotrione (Laudis) at 80g/ha (POST) at 2-4 leaf/10-15 DAS +one HW at 30 DAS and tembotrione (Laudis) at 100g/ha (POST) at 2-4 leaf/10-15 DAS +one HW at 30 DAS and two hand weedings at 15 and 30 DAS were compared, with weed free and weedy check. Seventeen treatments were tested using a randomised block design with three replications. Observations on growth studies, yield attributes and yield, weed studies, seed parameters and economics of pearl millet were recorded. The results obtained on climatic data revealed that rainfall received during the experimental period was 201.6 mm. It was well-distributed upto first week of September which resulted in good crop stand and growth and two irrigations were also applied to the crop. Important weed species observed in the experimental plots were Cyperus rotundus, Echinochloa colona, Trianthema portulacastrum and Digera arvensis. Application of Tembotrione (Laudis) 80g/ha (PoE) at 2-4 leaf/10-15 DAS and one HW at 30 DAS (T15) and Tembotrione (Laudis) 100g/ha (PoE) at 2-4 leaf/10-15 DAS and one HW at 30 DAS (T16) recorded significantly lower weed population, dry weight of weeds and higher weed control efficiency at all growth stages with good crop growth. In weed control method, effective control of weeds, higher grain and stover yield, net income and B: C were obtained with application of Tembotrione (Laudis) 80g/ha (PoE) at 2-4 leaf/10-15 DAS and one HW at 30 DAS (T15).ennullThesis
