Criado por: Júlio César Santos Pereira DEFINIÇÃO DO APLICATIVO: Este aplicativo foi desenvolvido para ajudar o produtor a avaliar a importância de mensurar cada linha do seu plantio e garantir uma melhor plantabilidade. A Distribuição Longitudinal, pode ser mensurada através de alguns parâmetros, sendo os principais o Coeficiente de Variação (CV%) e a regularidade de distribuição (aceitável, duplas e falhas) COEFICIENTE DE VARIAÇÃO: O coeficiente de variação é definido pela medida de dispersão dos espaçamentos entre sementes e/ou plantas em relação a média. Quanto maior for o valor de CV% maior é a variação em relação a média, ou seja, aumenta a irregularidade de distância entre as plantas. REGULARIDADE DE DISTRIBUIÇÃO: Outro parâmetro de qualidade da Plantabilidade é a regularidade de distribuição de plantas pode ser classificada em espaçamentos aceitáveis, duplas e falhas. Aceitável: Quando a distância entre as plantas for maior que 0,5 e menor que 1,5 vezes a distância ideal Dupla: Quando a distância entre as plantas for menor que 0,5 vezes a distância ideal Falha: Quando a distância entre as plantas for maior que 1,5 vezes a distância ideal CAUSAS DE ERRO: As causas de falta de uniformidade no plantio vão desde a velocidade do plantio, problemas com o disco dosador de sementes, regulagem geral da semeadora, profundidade uniforme de deposição de sementes, fechamento do sulco do plantio, manutenção da semeadora, etc. Instagram: @grupodeplantiodireto
