Abstract
The castor oil plant has a strong fitness culture as summer or winter harvest in Central Brazil, but the tropical soils have high natural acidity and low nutrient supply, which limits the production potential. Liming is a technique devoted to the management of tropical soils, however, the excessive use of lime can compromise crop development. Aiming to evaluate the vegetative growth and nutrient content in the shoot of castor oil plant, depending on the application of excessive doses of lime, settled experiment in pots in a greenhouse. The substrate was composed of soil classified as typic dystrophic Argisoil (Rhodustults-PVd) corrected with different doses of lime (0, 1, 2, 4 and 8 t ha -1 ). We used the cultivar Savana, leaving two plants per pot. Were assessed, considering the shoot, the dry matter and calcium, magnesium, potassium, sulfur and boron. It was concluded that the excess of limestone is detrimental to plant growth and K absorption by castor oil plant.
