چکیده
Direct drum seeding has emerged as a viable and alternate substitute to the current transplanted rice address constraints of labor water scarcity well rising cultivation costs. However, heavy weed infestation is main biological factor leading immense yield loss, which requires immediate attention. Therefore, adoption efficient management practice critical for success widespread direct seeded rice. In this regard, an experiment was laid out at Faculty Agriculture, Wadura, SKUAST Kashmir, India, in Kharif seasons 2018 2019 assess efficiency (DSR) under two sowing dates (D1: 10th May D2: 3rd June) six strategies (W1: weedy check (untreated check), W2: four mechanized conoweedings 15, 30, 45, 60 DAS (days after sowing), equivalent free (four conoweedings, free), W3: bensulfuron-methyl + pretilachlor @ 600 g a.i. ha–1 pre-emergence (BSM pretilachlor, PE), W4: oxyfluorfen 750 (oxyfluorfen, W5: followed by 2,4-D 0.75 kg post-emergence (30–35 DAS) PE fb PoE), W6: (oxyfluorfen PoE) on growth characteristics, productivity, infestation, nutrient dynamics. The pooled results showed that recorded significantly higher values characteristics viz. plant height, dry matter production, tiller count, including panicle weight, length, filled grains per panicle, test compared delayed (3rd June). Earlier (10th May) produced grain (7.33 t ha–1) straw (8.99 when 6.08 7.93 ha–1. Among strategies, conoweeding resulted enhanced growth, but statistically similar (BSM) (PoE). Delayed June; D2) density dry-weed biomass earlier May; D1). herbicides tested, sequential application BSM PoE proved with reduced population weight weeds. it concluded or promising improving productivity control temperate Kashmir conditions.

Field experiments were conducted during the 2 year period from 2008 and 2009 to determine the effects of three seeding dates and seven weed control methods in DSR. The results suggested that seeding in the first week of July reduced weed density and biomass, increased kernel weight, leaf area index, and kernel yield compared to seeding rice in the first week of July. Amongst weed control method...
