Abstract:
A field experiment was conducted at Agronomy research farm of CCS Haryana Agricultural University, Hisar, Haryana during Kharif 2017. 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 at 2-4 leaf stage/ 10-15 DAS viz., atrazine at 0.5 kg/ha application, atrazine at 0.75 kg/ha, tembotrione (Laudis) at 80g/ha and tembotrione (Laudis) at 100g/ha, two pre-emergence herbicides with one hand weeding at 21 DAS viz., atrazine at 0.4 kg/ha and pendimethalin at 0.75 kg/ha, one pre-emergence herbicides mixture with one hand weeding at 21 DAS viz., atrazine + pendimethalin at (0.4+0.75 kg/ha), three post-emergence herbicides with one hand weeding at 30 DAS viz., atrazine at 0.4 kg/ha (POST) at 10-14 DAS, tembotrione (Laudis) at 80g/ha (POST) at 2-4 leaf/10-15 DAS and tembotrione (Laudis) at 100g/ha (POST) at 2-4 leaf/10-15 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, yield, weed studies, seed parameters and economics of pearl millet were recorded. Predominant 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 + one HW at 30 DAS (T15) and Tembotrione (Laudis) @100g/ha (PoE) at 2-4 leaf/10-15 DAS + 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 + one HW at 30 DAS.
