Weed Dynamics of Hybrid Rice under the Influence of Fertilizer Levels and Weed Management Practices

摘要

A field experiment entitled "Weed Dynamics of Hybrid Rice under the Influence of fertilizer Levels and Weed Management Practices" was conducted during the Kharif season of 2017 at the Research Farm, TCA, Dholi, Dr. Rajendra Prasad Central Agricultural University, Pusa, Samastipur (BIHAR). The experiment was laid out in a split-plot design with twelve treatments. Among different levels of fertilizer, application of 100 RDF recorded a minimum number of weeds/m~2 (58.36/m~2), weed dry weight production (73.12 g/m~2), and weed growth rate (0.024 g/m~2/day). In the case of weed management practices, Hand weeding (twice) was found to be the most efficient weed control (71.32), a minimum number of weeds/m~2 (25.11/ m~2), weed dry weight production (21.12 g/m~2) and weed growth rate (0.011 g/m~2/day) but the minimum weed index (45.87) was observed in weedy check.
