Weed and nitrogen management in zero-till wheat (Triticum aestivum) grown after rice (Oryza sativa)

An experiment was conducted during 2020–21 at the Rani Lakshmi Bai Central Agricultural University, Jhansi, Uttar Pradesh to study effect of tillage, rice (Oryza sativa L.) residue, weed control and N fertilizer levels on weeds, growth yield wheat (Triticum aestivum L.). Weed infestation in zero-tillage (ZT) significantly lower (16.7–27.6%), more so when rice-residue retained soil surface compared with conventional tillage (CT). Post-emergence application sulfosulfuron + 2,4-D (ester) 30 days after sowing (DAS) provided near weed-free conditions, integration hand-weeding 45 DAS increased grain marginally (3.7–4.2%). The by 0.91–1.27 t/ha under ZT CT (2.27 t/ ha), greater response obtained additional (150 kg N/ha). Higher net returns (` 44,400 per ha) energy output (141,300 MJ/ha) 150 N/ha showed potential this technology Bundelkhand region.
