Abstract

To determine the impact of pre-emergence herbicides on the weed population, growth, and yield of garden pea cv. Kashi Nandini, a field experiment was carried out during the Rabi season of 2019–20 at the Horticulture Complex, Maharajpur, Department of Horticulture, J.N.K.V.V. Jabalpur (M.P.). The ten treatments, viz. T1 (Diquat @ 2500 ml/ha), T2 (Diquat @ 3500 ml/ha), T3 (Diquat @ 6000 ml/ha), T4 (Diquat @ 12000 ml/ha), T5 (Paraquat dichloride @ 2000 ml/ha), T6 (Pendimethalin @ 750 ml/ha), T7 (Oxyfluorfen @ 100 ml/ha), T8 (Pendimethalin 30% EC + Imazethapyr 2% EC @ 750+50 ml/ha), T9 (two hand weeding at 20 and 40 DAS) and T10 (Control). The herbicide T7 (oxyfluorfen at 100 ml/ha) was found to be superior to all other herbicides. The weed count of species is a major challenge of this study. The weed count of species contributes a major role in the weed population and yield estimate of garden peas.

Conclusion

Based on the results of the study, it is concluded that minimum weed density/m2 were obtained in weed free T9 (two hand weeding at 20 and 40 DAS) followed by Oxyfluorfen @ 100 ml/ha. Among the all pre-emergence application of herbicides, application of T7 (Oxyfluorfen @ 100 ml/ha) was most effective for control of weeds in vegetable pea but some weed species like Parthenium hysterophorus were suppressed at 20 DAS by Diquat @ 6000 ml/ha and Diquat @ 12000ml/ha. Performance of control treatment was recorded non effective in growth and yield of pea at any stage of crop duration. T7 (Oxyfluorfen @ 100ml/ha) was found superior in rest of all other herbicides.
