| dc.description.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. | |
