Furrow irrigated raised bed system being proposed for aerobic rice to increase productivity and to save water. Objective of the study were influence of the irrigation regimes and crop geometry on production performance of rice varieties/culture under aerobic condition. Keeping this as view, A field experiment was conducted at Agriculture College and Research Institute, Madurai, TNAU during 2014 and 2015 two consecutive years. The experiment was laid out in split split plot design with three factors viz. furrow irrigated raised bed system with three different levels of irrigation and crop geometry which is tested with six different varieties/cultures. The growth attributes viz. LAI and DMP at flowering stage and yield attributes (number of panicles and number of filled grains panicle-1), grain and straw yield were calculated. In both the years, among the different treatment combinations, the variety MAS IWM Saltol (V6) irrigated once in four days with close spacing of 20 x 10 cm (I1G1V6) recorded significantly higher LAI compared to other combinations. The variety APO1 (V2) irrigated once in four days with close spacing of 20 x 10 cm recorded significantly higher DMP. Among the treatment combinations, I1G1V6 was recorded significantly higher number of panicles/m2 and number of filled grains panicle-1compared to other treatment combinations. The highest grain and straw yield were recorded, variety APO1 grown in spacing of 20 x 10 cm and irrigated once in four days (I1G1V2) which is on par with I1G1V6.
