Study on the effect of plant materials on growth of lettuce varieties, Red Cos. Proceed to plan an experiment a Randomized Complete Block Design (RCBD)
Consists of 4 blocks (block 1 is 10.) The treatment are 1) Control 2) Expanded clay granules 3) coconut chop and 4) coconut fiber. Found that the growth of the trees in the field. The number of leaves, plant height, width and length, leaf size, canopy fresh weight of roots in control are likely to be most valuable. Differ significantly compared with expanded clay granules to values close to most control. Comparing with Expanded clay granules to the most similar to the control. But in parts of the coconut chop and coconut fiber are likely to make up the minimum. For fresh weight, leaves, root length, root number and size of the roots the treatment to the most In terms of the quality of lettuce varieties, Red Cos. The treatment that control Result, the most valuable areas equal to 72.32 cm
Which is not unlike the treatment used Expanded clay granules. In the color of the leaves the treatment that control and the treatment in coconut fibers that result the brightness value (L) at most equal to 43.78-43.83 and the color intensity (C) is equal to 4.01-4.03 In this section, the value of the color gamut (hue) Coconut fibers provide high-value process to 90.35 unlike other methods of statistics In terms of a value. Expanded clay granules and coconut chop make up most. For values b
control make up as much as possible, but do not differ with coconut chop and coconut fiber
