%X To obtain high quality seeds, required efficient and accurate control of all stages of production are required, from selecting seeds in the plant itself and processing. The objective of this study was to evaluate the influence of the order of racemes in fruit harvest and processing in three systems of quality of castor beans. The castor bean seeds were from the production field BRS 149 Nordestina, installed at the Experimental Station of Embrapa Algod o from Barbalha-CE. A completely randomized delineation was used, with a 3 x 3 factorial with four replications, where the factors were: harvest in three orders of racemes (primary, secondary, and tertiary harvested racemes) and three systems of processing (manual, manual machine, and mechanical machine peeling). The seeds from each treatment were subjected to germination tests, vigor, purity analysis, water content, and oil content. The secondary and tertiary racemes produce seeds with high physiological quality in relation to primary. The seeds peeled by a mechanical peeler machine provided greater seedling length, while the seeds processed manually had higher oil content. = Para a obten  o de sementes de alta qualidade, 谷 necess芍rio o controle eficiente e rigoroso de todas as etapas de produ  o, desde a escolha das sementes na pr車pria planta e beneficiamento. Objetivou-se com este trabalho avaliar a influ那ncia da ordem dos racemos na colheita dos frutos e de tr那s sistemas de beneficiamento na qualidade das sementes de mamona. As sementes de mamoneira foram provenientes do campo de produ  o da cultivar BRS 149 Nordestina, instalado na Esta  o Experimental da Embrapa Algod o de Barbalha-CE. Foi adotado o delineamento inteiramente casualizado, usando-se o esquema fatorial de 3 x 3, com quatro repeti  es, onde os fatores foram: colheita em tr那s ordens de racemos (frutos colhidos dos racemos prim芍rios, secund芍rios e terci芍rios) e tr那s sistemas de beneficiamento (manual, m芍quina descascadora manual e m芍quina descascadora mecanica). As sementes de cada tratamento foram submetidas aos testes de germina  o, vigor, an芍lise de pureza, teor de 芍gua e teor de 車leo. Os racemos secund芍rios e terci芍rios produzem sementes com melhor qualidade fisiol車gica em rela  o aos prim芍rios. As sementes descascadas em m芍quina descascadora mecanica proporcionaram maior comprimento das plantulas, enquanto as sementes beneficiadas manualmente apresentaram maior teor de 車leo.
