Abstract
Rice is an important cereal crop, both due to its high domestic consumption and its significant role in global food security. The challenges of crop rotation and the difficulty of fallow-free cultivation in rice production have led to the emergence of competitive weed species that have a rapid reproductive capacity and are adapted to aquatic environments. The adverse effects of these weeds on rice yield and farm profits have created a demand for cost-effective weed management strategies. Prolonged use of herbicides with the same mode of action has rapidly increased the number and population of herbicideresistant weed species. So integrated weed control is the only method and an important solution in managing the rice weeds that should be developed according to the countries’ production systems. Echinochloa crusgalli (barnyardgrass) is one of the earliest resistant weeds adapted to rice production areas. In this study, the aim was to determine the interaction between cultivation methods, water management, and rice varieties (Osmancık, Gönen, Koral) for effective weed management. The experiments were conducted in Turkey’s Marmara and Black Sea Regions with four replications. The water level, especially high water levels, not only had a highly suppressive effect on weeds but also contributed to the growth and yield of rice. Deep and moderate water levels increased the tillering number and dry weight of rice. The data obtained indicated that maintaining the water level in rice cultivation areas can lead to better rice growth and higher yields. The development of competitive and local rice varieties is considered a viable approach in an integrated herbicide-resistant weed control program.
