Abstract:
A field experiment entitled "Efficacy of pre and post-emergence herbicides on growth and yield of chickpea (Cicer arietinum L.)" was carried out at the Agricultural Research Station, Mandor, Jodhpur during the rabi season 2016-17. The investigation was laid out in the randomized block design (RBD) with sixteen treatments and replicated three times. Sixteen treatments were tested, with two doses of each herbicide, namely pendimethalin (0.40 and 0.60 kg a.i./ha), Oxyfluorfen (100 and 200 g a.i./ha), and imazethapyr (40 and 60 g a.i./ha), with their combinations as pre and post-emergence, including weedy check and weed free. Among the weed management 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 significantly reduced weed intensity at harvest that improved the productivity and profitability of chickpea over weedy check, but it was equally effective with the treatment combination pendimethalin @ 0.60 kg a.i. ha-1 (PE) + imazethapyr @ 40 g a.i. ha-1 at 20 DAS. Above treatments were also recorded higher weed persistence index, crop resistance index, herbicide efficiency index, weed management index and agronomic management index as compared to weedy check.
