Abstract:
The study entitled “Comparative Efficacy of Pre and Post Emergence Herbicides on Weed Control and Productivity of Pigeonpea [Cajanus cajan (L.) Millps.]” was conducted in “field no. 26 at the Research Farm of R.A.K. college of Agriculture, Sehore (Madhya Pradesh), during Kharif 2015. Experiment was laid out in randomized block design with four replications. Among the monocot weeds Echinochloa crusgalli Link., Degiteria sanguinalis, Dinebra arabica, Cyperus rotundus Linn. and Commelina benghalensis while the dicot weeds Acalypha indica Linn., Digera arvensis, Euphorbia geniculata and Phyllanthus niruri were observed in the field. Application of imazethapyr 35%+imazemox35% 70 WG 70g a.i/ha gave lowest weed dry weight and higher weed control efficiency (88.31%). Application of imazethapyr35%+imazamox35% 70 WG 70g a.i./ha recorded highest grain yield(1288 kg/ha) of Pigeonpea and effectively reduced weed population.
