DISEÑO EN PARCELAS DIVIDIDAS(factorial completo en parcelas divididas) Requiere -Minimo dos factores -Parecido a hacer dos veces el experimento (dos aleatorizaciones) -Riego, fertilizacion(goteo), densidad de siembra, labranza -Podria necesitar bloques, no es necesario

parcela principal:riego subparcela: variedad es mejor dejar el riego en una sola franja y no aleatorizarlo subdividiendo las parcelas Siempre debo explicar el porque de la parcela principal y la subparcela Doble aleaorizacion: una para el primer factor y otra para el segundo Tiene dos errores
