RESPON PERTUMBUHAN VEGETATIF TANAMAN JAGUNG MANIS (Zea mays L) TERHADAP BERBAGAI JENIS MULSA UNTUK PENGEMBANGAN BAHAN AJAR PADA KONSEP PERTUMBUHAN
ABSTRACT: Research has
been carried out in the
Laboratory of Biology
Teacher Training and Education Faculty of University of
Riau from April to August 2013. The goal of
this research is to
determine the best
type of mulch
to trigger the
vegetative growth of sweet
corn (Zea mays
L. var. saccharata)
and produce module
on the concept
of development and growth
concept for high
school students. This
research used experimental
methods with randomized block design
(CRD) with 5 treatments and 3 replications
so that there are 15 experimental units. Treatment are A0= without mulch, A1=
mulch reeds, A2= mulch palm empty fruit bunches, A3 = mulch black plastic, A4= white plastic bag. Biological parameters measured
were plant height, stem diameter, fresh
weight and dry
weight. Physic-chemical parameters
are soil temperature,
soil moisture, and soil
pH. The data
were analyzed by
ANOVA and tested
further by DMRT at 5% level.
The results showed
that the use
of mulch influence
on stem diameter and dry weight
of sweet corn plants, but not in the
height and wet weight of the plant.
The use of
oil palm empty
fruit bunches mulch
gave best result
on the parameter plant height
(86,54 cm), stem diameter (1,80 cm),
fresh weight (191,7 g) and sweet corn
plant dry weight
(43,33 g ).
The results of
this research can be
developed into module on the concept of
plant growth for high school students
with the title of
“Pengaruh Beberapa Jenis
Mulsa Terhadap Pertumbuhan
Vegetatif Tanaman Jagung”.
Keywords: Corn, Dry weight,
