Title A name given to the resource Avaliação do desempenho de semeadoras manuais Evaluation of manual planters Creator An entity primarily responsible for making the resource José P. Molin, Leonardo A. A. Menegatti, Leandro M. Gimenez Description An account of the resource Um grande número de pequenas propriedades rurais no Brasil utiliza semeadoras manuais para a operação de semeadura. O fator limitante para a utilização de tratores e equipamentos de maior rendimento nessas condições são terrenos pedregosos ou declivosos e disponibilidade de capital. As semeadoras manuais existentes no mercado mantêm o mesmo princípio desde o início de sua utilização e não sofreram grandes melhorias. Neste trabalho avaliaram-se semeadoras existentes no mercado, classificando-as quanto à regularidade de vazão dos seus mecanismos dosadores. Para a avaliação estabeleceu-se, como meta, a vazão de duas sementes por ciclo. Algumas semeadoras resultaram em baixo desvio-padrão e média próximo de duas sementes por ciclo, enquanto outras apresentaram desempenho deficiente. Não houve algum tipo de mecanismo dosador que se destacasse, sendo seus efeitos encobertos pela qualidade construtiva das máquinas.In Brazil, a great number of small farms still use manual planters, especially in hilly and stony areas. These machines have not received significant design improvements since the start of their usage. Some of these planters available in the market have been tested for their seeding performance for corn. Each machine was set up to deliver two seeds each time. Only a few planters resulted in a low standard deviation and number of seeds close to the target. The performance of the seed meter was affected by the manufacturing quality of the machines.
