Abstract: Field experiments were conducted at Tamil Nadu Rice Research Institute, Aduthurai during 2016-2018. Field experiments were laid out in randomized block design with four replications. The six treatments under system basis were T1 - NPTR (Kharif) - NT (Rabi) - NT (Summer), T2 - NPTR (Kharif) - PTR (Rabi) - NT (Summer), T3- DSR (Kharif) - NT (Rabi) - NT (Summer), T4 – DSR (Kharif) - PTR (Rabi) - NT (Summer), T5 – PTR (Kharif) - NT (Rabi) - NT (Summer) and T6- PTR (Kharif) - PTR (Rabi) - NT (Summer). The results revealed that among different crop establishment methods, dry seeded rice(DSR) produced significantly higher growth attributes, weed and water parameters which ultimately resulted in higher yield attributes, grain and straw yields during both the years of kharif season. During rabi seasons, among different crop establishment methods, puddled transplanted rice (PTR) preceded by dry seeded rice (DSR) produced significantly higher growth parameters, weed and water parameters which eventually resulted in higher yield attributes, grain and straw yields.
