Esse sistema produtivo possui uma carência de máquinas agrícolas. Para atender a demanda e facilitar o processo de semeadura desses agricultores o trabalho tem objetivo de desenvolver uma semeadora de tração animal e avaliar um novo conceito do sistema de semeadura em fita, comparando com uma semeadora de tração animal já existente no mercado e com seu sistema de semeadura. O trabalho foi desenvolvido na safra 2013/2014 e 2014/2015 com a cultura do milho, no câmpus do Centro Universitário Moura Lacerda na cidade de Ribeirão Preto- SP. As variáveis avaliadas foram a profundidade da semente no sulco de plantio, distância longitudinal entre as plantas, comprimento da inserção da espiga, diâmetro do colmo e massa de grãos. Para avaliar a qualidade da operação foi realizado o controle estatístico por meio de carta de controle, utilizando o minitab. Após essa avaliação e analise dos dados o processo de semeadura da semeadora de fita de tração animal apresentou resultados mais estáveis do que a o processo de semeadura da semeadora de tração animal tradicional. / The family agriculture is responsible for 50% of the maize production in Brazil. This production system has a shortage of agricultural machinery. To meet the demand and facilitate the process of sowing of these farmers work's goal of developing a sower of animal traction and evaluate a new concept of seeding system to tape, comparing with a sower of existing animal traction in the market and with its seeding system. The work was developed on crop 2013/2014 and 2014/2015 with the culture of corn, on the campus of the Centro Universitário Moura Lacerda in the city of RibeirãoSP. The variables evaluated were seed in the furrow depth of planting, longitudinal distance between plants, insert Tenon length, culm diameter and mass of grain. To assess the quality of the operation was carried out by means of statistical control chart control, using the minitab. After this evaluation and analysis of data the process of seeding the sower of animal traction tape showed results more stable than the process of seeding the sower of animal traction.
