Abstract:

A field experiment was conducted at the Livestock Farm, JNKVV, Jabalpur during Rabi season 2017 and 2018 to check the bio-efficacy of pendimethalin (38.7% CS) as PPI against complex weed flora in chickpea. Species wise weed data were recorded in weedy check plots revealed that Medicago denticullate (62.08%) and Cichorium intybus (32.85%) were most dominant. However, other monocot weeds like Cyperus rotundus (3.12%), Cynodon dactylon (1.95%) were also present in less numbers in chickpea. Weedy check had the highest weed density and weed biomass, which reduced significantly when weeds were, controlled either chemically or mechanically. Among the herbicidal treatments, application of pendimethalin (38.7% CS) as PPI at 774 g/ha arrested the weed density and weed biomass production remarkably and proved superior to its lower doses (580 and 677 g/ha) as PPI and its pre emergence application from 580 to 774 g/ha. Superior growth parameters (plant height, number of branches per plant, effective nodules per plant and crop biomass); yield attributes (pods per plant, seeds per pod, seed index), higher seed and stover yields were recorded in plots receiving pendimethalin (38.7% CS) as PPI from 677 g/ha to 774 g/ha over other herbicide treatments including its application as pre emergence at the same rates (677 and 774 g/ha). However, none of the herbicidal treatments found superior to the hand weeding twice (15 and 30 DAS).
