APPLICATION OF CHICKEN MANURE AND SHADING ON CARROT (Daucus carota L.) GROWTH AND YIELD.
Carrot is a highland plant that is mostly grown in monoculture and intercropping systems. There are even some were grown under / between perennial trees. However, this system causes the decline of light intensity,Â nutrient and water. In line with this phenomenon, a research was conducted to determine the influence of chicken manure and shading on carrotâ€™s growth and yield. Â The research was conducted in the Junggo Village, Batu city, using Split Plot Design. There were two treatments i.e: (1) as main plot, namely the percentage of shading consisting of four levels:Â 0 %, 20 %, 40 % and 60 %. The shading material used was black plastic net; (2) as sub plot, namely chicken manure dosage consisting of three levels: 10 tons/ha, 20 tons/ha and 30 tons/ha. The twelve treatment combinations obtained were replicated three times. The result showed that the treatment of 20 tons/ha chicken manure onto carrot grown with no shading increased the growth and yield. This treatment, however, did not show a significant difference in the growth and yield when applied to carrot grown with shading. The treatment of 20% shading, yielded a good plant growth although accompanied by the decrease in the fresh tuber weight by 14 % and the increase in beta carotene content. The application of 10 tons/ha did not show difference in the growth and yield of carrot treated with 20 tons/ha and 30 tons/ha of chicken manure.
