A field experiment was conducted at Tamil Nadu Rice Research Institute, Aduthurai during Kuruvai, 2013 to study the effect of conservation tillage practices and cultivars on growth, yield and economics of rice. The experiments were laid out in strip plot design with three replications. The main plot treatments comprised of three levels of conservation tillage practices (conventional tillage, zero tillage and minimum tillage) and two rice cultivars (Hybrid (CORH - 3) and high yielding variety (ADT - 43)) were assigned to sub plots. The results revealed that the among different conservation tillage practices, higher growth, yield parameters, yield, net return and BC ratio were registered under conventional tillage practices. This was followed by minimum and zero tillage practices. Between rice cultivars tested, CORH-3 recorded higher growth, yield parameters, yield, net return and BC ratio than ADT - 43. Hence, it was concluded that rice cultivar CORH-3 cultivated under conventional tillage recorded higher growth, yield, net return and BC ratio.
