Effect of integrated weed management on weed dynamics in pearlmillet (Pennisetum glaucum L.)

Abstract

A field experiment was conducted at Research farm, Vivekananda Global University, Jaipur during kharif, 2023 on loamy sand soil. The experiment comprises 10 treatments of weed management practices (Weedy check, weed free, One hand weeding at 20 DAS, Two hand weeding at 20 and 40 DAS, Alachlor @ 1.0 kg ha-1 (PE), Alachlor @ 1.0 g ha-1 (PE)+ One hand weeding at 20 DAS, Atrazine @ 500 g ha-1 (PE), Atrazine @ 500 g ha-1 (PE) + One hand weeding at 20 DAS, Oxyfluorfen @ 150 g ha-1 (PE), Oxyfluorfen @ 150 g ha-1 (PE)+ One Hand Weeding at 20 DAS) thereby experiment was laid out in randomized block design and replicated thrice. Results showed that application of after weed free plot, two hand weedings at 20 and 40 DAS treatments resulted significant reduction in weed density, weed dry matter in comparison to most of the treatments while highest weed control efficiency and lowest weed index was recorded with the same treatment.
