Castor bean is an important oil plant, which in Romania is cultivated on small areas for scientific, ornamental, industrial and medicinal purposes. Having into consideration the importance of the crop in the past, respectively up to 1989, when Romania was the sixth largest cultivator of castor bean in the world, and having in view the great importance of its oil, it can be said that in Romania the castor bean has a real potential to develop in the future.Optimizing row spacing and plant density has a significant influence on seed yield. Therefore, our research focused on determining the optimal combination of row spacing and plant density to obtain the best yield under the environmental conditions specific to the South Romania and taking into account the phenotypic expression of the cultivated variety. Researches were performed in field conditions at the Agricultural and Development Research Station Teleorman located in Teleorman County in South Romania, in the years 2019 and 2020 and on cambic chernozem soil conditions. The experiment was placed according to the method of subdivided plots into 3 replications, with the following factors: Factor A - row spacing, with 4 graduations (30, 50, 70 and 90 cm); Factor B - plant density, with 3 graduations (40,000, 60,000 and 80,000 plants/ha); Factor C - castor bean variety, with 2 graduations (Teleorman and Rivlas). The results of the performed research proved that decreasing the row spacing is associated with decreasing of yield, while increasing the plant density is associated with increasing of yield. The Rivlas variety turned out to be more productive than the Teleorman variety.
