| This study aimed to find out the odor and irrigation contamination by duck-rice farming systems and its weed control, rice growth and yield under the system with hairy vetch cultivation. Rice yield was reached at 4.1t/ha in the plot of duck-rice + hairy vetch cultivation while the plot of duck-rice achieved only 3.9t/ha. The nitrate nitrogen concentration in irrigated water ranged between 0.17 and 0.37ppm and did not show much difference among the treatments until the end of June, but the maximum difference detected was in the duck-rice plot in July, 0.11ppm, compared to the hairy plot and duck-rice + hairy vetch plot, 0.08ppm and 0.09ppm respectively. But the concentration of ammonium nitrogen at the end of July reached 4.07ppm in the plot of duck-rice,... |

| Organic agriculture can and should play an important role in solving future challenges in producing food. The low level of external inputs combined with knowledge on sustainablity minimizes environmental contamination and can help to produce more food for more people without negatively impacting our environment. Organic agriculture not only includes farming as a production practice but it also includes processing, trade and consumption. Nevertheless, Organic agriculture must always evolve to overcome emerging challenges. Science-based knowledge attained through dedicated research is required to strengthen organic food and farming as a means to solve future challenges. In 2010, a global discussion about Organic 3.0 was initiated to address current problems... |
