Abstract:
This study aims to look at the growth and yield of lettuce (Lactuca sativa. L) with the administration of multiple doses of composts empty fruit bunches of oil palm. The research was done experimentally by usingcompletely randomized design, which consists of 5 treatments. Each treatment was repeated 4 times to obtain 20 units of the experiment, one experimental plot contained 25 plants, as well as samples taken 4 plants. The results showed that administration of compost TKKS significant effect on all parameters except leaf width. TKKS composting showed significantly different results or the effect of the parameters of plant height, leaf number, root volume, and plant fresh weight. TKKS composting at treatment doses of 1.5 kg / plot gives the best results for all of the parameters that increase plant height, leaf number, leaf width, root volume and fresh weight of lettuce plants. Observations on leaf width parameters showed different results is not real, it is influenced by the spacing is less efficient, so berdanpak the amount of solar radiation absorbed by plants, plant spacing also affects the initial growth phase, determining leaf width sufficient to absorb maximum sunlight .
