Abstract

In order to study the effect of water level and soil depth on the GERMINATION rates of barnyard grass and RICE BARNYARD GRASS, an investigation was conducted at Rice Research Institute of Iran (Rasht) in 2008. Treatments included weed species (Echinochloa Crus-galli and Echinochloa oryziodes), water level (0, 3, 6 and 9 cm) and soil depth (0.5, 1.5, 2.5 and 3.5 cm). The experimental design was a Randomized Complete Block Design (RCBD) with three replications in factorial arrangement. Experiment were laid out in covered outdoor conditions. Results showed that water level and soil depth affected GERMINATION rate, seedling mortality, seedling GERMINATION, height, dry matter accumulation and radicle length, significantly. Both water level and soil depth affected barnyard grass more than RICE BARNYARD GRASS. Average GERMINATION of seeds in 9 cm of water was 80% and 30% for RICE BARNYARD GRASS and barnyard grass 20 day after sowing, respectively. Also increasing soil depth decreased seed GERMINATION significantly. Regression analysis showed that by increasing water level and soil depth, the GERMINATION rate of barnyard grass decreased more than RICE BARNYARD GRASS. This study showed that RICE BARNYARD GRASS is more tolerant than barnyard grass to water level or soil depth. These results indicate that RICE BARNYARD GRASS has more chance to survive in paddy field of Iran.
