Abstract
Se estudió el efecto de compostas y una mezcla comercial usados como sustratos en el cultivo de girasol y marigol en tiesto. Se llevaron a cabo dos ensayos evaluando la conductividad eléctrica del sustrato con 4 niveles (1.3, 3.4, 4.7 y 6.7 mS/cm), mezclas con 3 niveles (café, gallinaza y Promix) y dos especies ornamentales, en un arreglo factorial dentro de un DBCA. Datos tomados incluyeron la altura y circunferencia de tallo, diámetro de flor y peso húmedo y seco a los 15, 30 y 45 dÃas después del trasplante de bandeja a tiesto. En términos generales, el comportamiento de girasol y marigol en los tratamientos 1, 2 y 3 (mezclas de composta de café) fueron superior a los tratamientos 7, 8, 9, 10, 11 y 12 (composta de gallinaza y Promix). También se llevó a cabo una encuesta sobre las preferencias de mercado: los consumidores optan por precios bajos, tamaño grande del producto por vistosidad y poder siempre comprar las flores en un solo lugar como el supermercado ahorrando tiempo y dinero.
The effect of different composts and a commercial mix as substrates was studied in sunflower and marigold in pots. Two studies were conducted to evaluate four levels of electrical conductivity (1.3, 3.4, 4.7 y 6.7 mS/cm), in coffee compost, chicken manure compost and Promix in a RCBD with factorial treatment arrangement. Observations included stem height and circumference, flower diameter and plant fresh and dry weight at 15, 30 y 45 days after transplanting from cell trays to pots. In general terms, plant performance of sunflower and marigold in treatments 1, 2 and 3 (coffee compost mixes) was superior to treatments 7, 8, 9, 10, 11 and 12 (chicken manure compost and Promix). A survey of market preferences was also conducted: consumers preferred low prices, large plant size and an easy place to buy plants as well as other items (supermarket).
