To study the performance of different crop establishment methods of rice-rice sequence on growth, weeds dynamics and yield, the field experiments were conducted during Kharif 2016 and Rabi 2016-17 seasons at Tamil Nadu Rice Research Institute, Aduthurai. Treatments consisted of T1– Non- puddled transplanted rice (NPTR) in kharif – No Till (NT) in rabi, T2 – NPTR in kharif – Puddled transplanted rice (PTR) in rabi, T3 – Dry Seeded Rice (DSR) in kharif – NT in rabi, T4 – DSR in kharif – PTR in rabi, T5 – PTR in kharif– NT in rabi and T6 – PTR in both kharif and rabi. The results revealed that the growth viz plant height, DMP and yield parameters viz panicles m-2 and grain yield were higher in DSR than PTR in kharif 2016 and same were higher in DSR followed by PTR during rabi 2016-17. The weed density and dry weight was higher in DSR and NPTR than PTR during kharif 2016 and in DSR followed by NT during rabi 2016-17.
