Abstract: The objective was to evaluate the effect of detoxified castor bean replacing soybean meal in the concentrate diet or as nitrogen organic fertilizer replacing urea on intake and nutrient digestibility, blood parameters and productive performance of sheep finished on irrigated Tamani grass pasture under continuous stocking and variable stocking rate. The treatments were two concentrate diets: standard (ground corn and soybean meal) and alternative diet (ground corn and detoxified castor bean cake), and two nitrogen fertilizers: chemical (urea) and organic (fresh castor bean cake). The randomized complete block design was used in a 2 × 2 factorial arrangement with four replications (500 m² paddocks). Four sheep (2 castrated males and 2 females) were distributed in each experimental unit, totaling 64 animals with an average initial weight of 19.42 ± 3.6 kg. No effects (P > 0.05) were observed on the variables inherent to the evaluation of the pasture. The average stocking rate (SR) among treatments was 85.50 sheep/ha, equivalent to 9.87 Animal Units (AU)/ha. The alternative diet presented lower dry matter digestibility (62.71%), with no negative effects on nutrient intake and kidney parameters. Animals fed the standard and alternative diet showed average daily gain of 103.75 and 86.76 g/day, respectively. A finishing period of up to 100 days is recommended for sheep selected for production systems in semi-arid regions managed intensively on pasture. Detoxified castor bean cake did not alter nutrient intake, liver and kidney parameters of the sheep and can be used in pasture-based sheep farming.

ABSTRACT - The objective of this work was to evaluate the relationship between grain yield and production costs of flood-irrigated rice (Oryza sativa) in the state of Rio Grande do Sul, Brazil, in order to determine the yield range that maximizes the profit of farmers. There are estimations pointing out that the yield range that maximizes the profit for farmers is about 75 and 85% of the yield potential; however, this still needs to be validated for irrigated rice in Brazil. To validate these values, a technical and economic monitoring was carried out for eight farmers of irrigated rice, whose production costs were measured and compared with the mean yield and the percentage of potential yield achieved. To determine the potential yield of each crop, SimulArroz, a process-based model developed for the simulation of rice growth and yield in the South of Brazil, was used. The grain yield achieved by the farmers ranged from 6.3 to 11.0 Mg ha-¹ (48 to 83% of the potential yield), costs ranged from R$4,197.00 ha-¹ t o R $6,227.00 ha-¹, and profit ranged from R$-52.00 ha-¹ to R$3,599.00 ha-¹. Farmers who reach between 69 and 83% of yield potential achieve the highest profitability. The investment planning based on the yield potential calculated by the SimulArroz model can be efficiently adopted for irrigated rice crops. RESUMO - O objetivo deste trabalho foi avaliar a relação entre a produtividade de grãos e os custos de produção de lavouras de arroz (Oryza sativa) irrigado por inundação, no estado do Rio Grande do Sul, Brasil, para determinar a faixa de produtividade que maximiza o lucro do produtor. Existem estimativas de que a faixa de produtividade que maximiza o lucro para os agricultores é de cerca de 75 a 85% do potencial de produtividade; porém, isso ainda precisa ser validado para a cultura do arroz irrigado no Brasil. Para validar esses valores, foi realizado um acompanhamento técnico-econômico para oito produtores de arroz irrigado, cujos custos de produção foram determinados e comparados com a produtividade média e a percentagem da produtividade potencial atingida. Para determinar o potencial produtivo de cada lavoura, utilizou-se o SimulArroz, um modelo, baseado em processos, desenvolvido para a simulação do crescimento e da produtividade de arroz no Sul do Brasil. As produtividades atingidas pelos produtores variaram de 6,3 a 11,0 Mg ha-¹ (48 a 83% do potencial de produtividade), os custos variaram de R$ 4.197,00 ha-¹ a R$ 6.227,00 ha-¹, e o lucro variou de R$ -52,00 ha-¹ a R$ 3.599,00 ha-¹. Produtores que atingem entre 69 e 83% do potencial produtivo alcançam maior lucratividade. O planejamento de investimento com base no potencial produtivo, calculado pelo modelo SimulArroz, pode ser adotado eficazmente nas lavouras de arroz irrigado.
