Effect of integrated nutrient management and weed control measures on weed dynamics in pearlmillet (Pennisetum glaucum L.)

Abstract

A field experiment was conducted at Research farm, Vivekananda Global University, Jaipur during kharif, 2024 on loamy sand soil. The experiment comprises 6 treatments of nutrient management practices (Control, 100 % RDF (60 kg N + 30 kg P2O5), 100 % RDF + FYM 10 t ha-1, 75 % RDF + FYM 10 t ha-1, 75 % RDF + FYM 10 t ha-1 + Bio-fertilizer (Azospirillum and PSB), 50 % RDF + FYM 10 t ha-1 + Bio-fertilizer (Azospirillum and PSB) and three treatment of weed control measures (Weedy check, Weed free and Atrazine @ 500 g ha-1 (PE) thereby experiment was laid out in randomized block design and replicated thrice. Results showed that application of Atrazine@500 g ha-1 (PE) treatment 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 except weed free.
