Abstract:
To study the effect of different pre-emergence herbicides on physiological growth parameters of groundnut (Arachis hypogaea L.) a field trial was conducted at Central farm, OUA & T, Bhubaneswar during Rabi 2014-15. This experiment was operated with five treatments such as weedy check (control), butachlor, alachlor, oxyfluorfen and weed free check (hand weeding) with three replications under Randomize Block Design (RBD). Our studied revealed that among all pre-emergence herbicides application of butachlor (50% EC) @ 1000ml ha-1 effectively controls weed population and recorded the highest values of growth. In contrast to this, application of alachlor adversely affected and noted the lowest value of growth. The physiological growth parameters such as LAI, SLA, SLW, LAR, RGR, NAR and CGR significantly responded to herbicides application over the weedy check (control). All the above mentioned physiological parameters are highly correlated with pod yield of groundnut.
