Pengaruh Tinggi Muka Air Tanah Dan Aplikasi Mulsa Organik Terhadap Laju Dekomposisi Mulsa Dan Hasil Jagung Manis Di Media Gambut

Peat soil as agricultural land has various obstacles, one of the problems is the
decrease in the groundwater level. Therefore, water management is an absolute
necessity for agricultural activities on peatlands. Another effort to provide a good
growing environment for corn plants can be supported by the application of organic
mulch. The purpose of this study was to study the interaction between the groundwater
level of peat and organic mulch, and to analyze the effect of the groundwater level of
peat and the application of organic mulch on the decomposition rate of mulch and yield
of corn. This research was conducted at Air Terbit Village, Kampar Regency, Riau
Province and the Soil Laboratory, Faculty of Agriculture, University of Riau, from
February to July 2021. This research used a factorial complete randomized design
(CRD) method consisting of 2 factors. The first factor was the various of the
groundwater level which consisted of 3 levels (30 cm, 40 cm and 50 cm), while the
second factor was the various types of organic mulch (without mulch, empty oil palm
bunches, rice straw and corn stover). Parameters observed were decomposition rate,
total cellulolytic microbial population, soil chemical properties and corn yield. The
results showed that the combination of groundwater level (GWL) treatment with organic
mulch did not show any interaction on the decomposition rate of mulch and corn yields.
However, there was an interaction between the GWL treatment and organic mulch for
the elements N, P, K, CEC, Ca and Na. Based on the correlation test, increases in Corganic
and CEC were negatively correlated with corn yields. Therefore, the
groundwater level should be maintained at 40 cm GWL and rice straw mulch
application. The best groundwater level for the rate of decomposition is at 40 cm GWL,
while the mulch that decomposes the fastest is rice straw mulch. The 40 cm GWL
treatment and rice straw mulch respectively also increased the weight, length and
diameter of corn cobs higher than the other treatments. The application of organic mulch
generally increased the number of rows of seeds, fresh weight and dry weight of stover,
cellulolytic fungi population and pH compared to no mulch.
