Abstract. Despite being relatively high (7.7 t ha-1), the average yield of irrigated rice in the State of Rio Grande Sul (RS) can be even higher, if the management practices are carried out at the most appropriate time, considering the date of occurrence of the main stages of plant development (PDS). The objective of this article was to demonstrate the fundamentals and applications of the software PlanejArroz to estimate the date of occurrence of six PDS, aiming the crop management, and the expected grain yield. Based on the degree-day method, the software estimates the date of each of the six PDS, using historical series (30 years) of climatic data, and updates these estimates using the current season´s meteorological data. This information can be generated for 131 rice producing municipalities and for 41 cultivars recommended for cultivation in RS. Likewise, grain yield, for the three most sown cultivars, can be estimated as an average of 30 years and for the current cropping season. The PlanejArroz is a tool that allows management practices to be carried out at the most appropriate time, estimating the date of the occurrence of six PDS associated with these practices. It is also possible to simulate the most appropriate sowing dates and to obtain the expected average grain yield for the current season. |

In aquaculture, biological treatments usually have an excellent benefit-cost ratio. This study evaluated the efficiency of different ecotechnologies on aquaculture wastewater treatment. Two experimental units were installed. In the first one, tanks were individually vegetated with free-floating aquatic macrophytes. In the second experimental unit, 10.72 m² of artificial substrate were added for periphyton colonization. The hydraulic retention time of the wastewater was of 30 days. Both physical and chemical characterizations of the effluent were carried out at the beginning and at the end of the experiment. The periphyton community attached to the substrate was catalogued. In the first unit, the pH, nitrite, and orthophosphate values were significantly different. The tanks vegetated with Azolla filiculoides were the only ones where the electrical conductivity values were reduced. Tanks vegetated with Azolla filiculoides and Pontederia crassipes presented decreased the nitrate concentration. On the other hand, the concentration of ammonia and total phosphorus decreased in all vegetated tanks. In the second unit, only the nitrate and ammonia values did not decrease in the last day of the experiment. 33 taxa belonging to the classes Cyanophyceae, Chlorophyceae, Bacillariophyceae, Trebouxiophyceae, Coleochaetophyceae, Coscinodiscophyceae and Zygnematophyceae were identified in the substrate. The experimental units were effective in mitigating the nutrients in aquaculture wastewater that cause eutrophication.
