A field experiment entitled “Efficacy of pre and post-emergence herbicides on growth and yield of chickpea (Cicer arietinum L.)” was conducted at Agricultural Research Station, Mandor, Jodhpur during rabi season of 2016-17. Field experiment was laid out in randomized block design (RBD) with sixteen treatments and replicated thrice. Sixteen treatments were tested among that two doses of each herbicides i.e. pendimethalin (0.40 and 0.60 kg a.i./ha), oxyfluorfen (100 and 200 g a.i./ha), imazethapyr (40 and 60 g a.i./ha) with their combinations as pre and post-emergence including weedy check and weed free taken for computing WCE and WI, respectively. According to treatments, different doses of pendimethalin and oxyfluorfen were applied as pre-mergence (within 3 DAS), while imazethapyr was applied as post-emergence (20 DAS). Among treatments, sequential application of pre and post-emergence herbicides i.e. pendimethalin @ 0.60 kg a.i. ha-1 (PE) + imazethapyr @ 60 g a.i. ha-1 at 20 DAS (W12) significantly reduced weed density of Chenopodium murale L., Chenopodium album L. and Rumex dentatus L. at 30, 60, 90 DAS and at harvest, that improved the seed yield of chickpea, but it was equally effective with treatment had received pendimethalin @ 0.60 kg a.i. ha-1 (PE) + imazethapyr @ 40 g a.i. ha-1 at 20 DAS (W11) as pre and post-emergence combination. Although, weed free recorded higher seed yield and showed significant superiority over rest of the weed management treatments, but it was statistically at par with W12 and W11.
