Abstract
A field experiment entitled “Herbicidal weed management in chickpea
(Cicer arietinum L.)” was conducted at Instructional Farm, Mandor, Jodhpur during
Rabi season of 2021-22. Field experiment was laid out in randomized block
design (RBD) with Ten treatments and replicated thrice. The treatments taken
in the investigation were T1- Imazethapyr @ 50 g/ha at 20 DAS,
T2- Propaquizafop+imazethapyr @ 50 g/ha at 20 DAS, T3- Sodium
Acifluorfen+clodinafop propargyl @ 200 g/ha at 20 DAS, T4- Fomesafen+fluazifop-p-butyl @ 200 g/ha at 20 DAS, T5- Bentazon @ 750 g/ha at 30 DAS,
T6- Pendimethalin+imazethapyr @ 750 g/ha as PE, T7 – Pendimethalin @ 750 g/ha as
PE, T8- Sulfentrazone @ 75 g/ha as PE, T9- Weed Free and T10- Weedy Check.
Among treatments, application of pendimethalin+imazethapyr @ 750 g/ha as PE
significantly reduced weed density of Chenopodium murale L., Chenopodium album
L. and Rumex dentatus L. as well as total density and dry weight of weeds at 30, 60,
90 DAS and at harvest. Similarly, higher weed control efficiency and Weed index was
also obtained under these treatments. Weed free recorded significantly higher growth
and yield attributing characters and yields over rest of the treatments. Among
herbicidal treatments, plant height, no. of branches/plant, dry matter accumulation
(g/m2) as well as yield attributing characters viz., no. of pods/plant, no. of seeds/pod,
100-seed weight and seed yield/plant of chickpea were produced significantly higher
under application of pendimethalin+imazethapyr @ 750 g/ha as PE resulted in higher
seed and stover yield. Despite higher yield and net returns, returns per rupee of
investment (B:C ratio) were low with weed free treatment due to higher labour wages.
Increase in seed and stalk yield, which subsequently improved gross returns, net
returns and B: C ratio also and recorded highest under pendimethalin+imazethapyr @
750 g/ha as PE.
