Özet:

The study aimed to analyze the quality of the compost from various organic wastes and its effect on germination, growth and production of sweet corn. Four organic waste (e.g. bagasse, filter cake, market organic-waste, and water hyacinth) were chosen as raw materials of compost. The composting method uses an open windrow system. Differences in raw materials of compost resulted a different in compost quality. In addition, compost from filter cake, market organic-waste, and water hyacinth have good qualities, indicated by C/N ratio 8,06-11,00, pH 7,86-8,70, nutrient content (N+P2O5+K2O) > 2 %, and water content 10-15%. In addition, compost from market place tended to accelerate percentage of germination and speed of growth sweet corn as compared to the other compost and control (pure water). Application of market waste compost with a dose of 10 t/ha had the highest average for plant height (165 cm) and the number of leaves (11 strands). Meanwhile, the application of bagasse compost with a dose of 5 t/ha had the highest level of sweetness, which is 12%.The study found the benefit of organic waste to speed up germination, growth, and quality of sweet corn, with composting process.
