Abstract:
A field experiment was conducted during kharif season of 2020-21 at Mega Seed, Pulses and Castor Research Unit, Navsari Agricultural University, Navsari to study the effect of herbicidal treatments on yield and weed attributes of pigeon pea based cropping system under large plot technique design. Application of pendimethalin 2000 g/ha gave significantly lowest weed population of monocot, dicot, sedge and total weeds at 60 and 90 DAS which was remain at par with the treatment of pendimethalin 1000 g/ha. The application of pendimethalin 1000 g/ha showed significantly lowest dry weight of weed at 90 DAS and at harvest which was remained at par with treatment of pendimethalin 2000 g/ha followed by imazethapyr 75g/ha, imazethapyr 150g/ha, oxyfluorfen 125 g/ha and oxyfluorfen 250 g/ha, respectively. Significantly higher seed yield and stalk yield was recorded under the application of pendimethalin 1000 g a.i./ha (T₂) at harvest and stood at par with the treatment of pendimethalin 2000 g a.i./ha followed by imazethapyr 75g/ha, imazethapyr 150g a.i./ha, oxyfluorfen 125 g a.i./ha and oxyfluorfen 250 g a.i./ha.
