    A diversidade de climas determina perodos de plantio

    e colheita distintos para as diversas regies.

    Em So Paulo, de modo geral, planta-se de outubro amaro e colhe-se de maio a outubro; enquanto no

    nordeste o plantio se faz de julho a novembro e a

    colheita de dezembro a maio.

    A cana-de-acar exige calor e umidade. Sem essas

    condies no produzir bem. A melhor temperatura

    para a cana de 30 a 34C. Abaixo de 20C ocrescimento muito lento. Acima de 35C tambm

    lento, e alm de 38C nulo.

    Tendo a cana-de-acar um sistema radicular

    profundo, um ciclo vegetativo econmico de quatro

    anos e meio ou mais e uma intensa mecanizao quese processa durante esse longo tempo de

    permanncia da cultura no terreno, o preparo do solo

    deve ser profundo e esmerado.
