Utilization of Monosodium Glutamate (ami-ami) Factory by-Product and Fly Ash on Yield and Yield Components of Maize

Abstract

This study was to investigate the utilization of monosodium glutamate (ami-ami) factory by-product
and fly ash on yield and yield components of maize var. Pacific 999. The experiment was done 2 crops in
a Randomized Complete Block Design (RCBD). The 1st crop, it revealed that the application of organic
mixture material (OMM) of 1,000 kg/rai in combination with chemical fertilizers containing all major elements
equivalent to 1,000 kg/rai of the OMM affected on the highest of ear weight, ear without husk weight, grain
weight and 1,000 grain weight which were not different from the applications of chemical fertilizers containing
all major elements equivalent to 2,000 kg/rai of the OMM and the application of chemical fertilizer based
on soil chemical analysis. The 2nd crop, it revealed that the application of OMM of 1,000 kg/rai in combination
with chemical fertilizers containing all major elements equivalent to 1,000 kg/rai of the OMM affected on
the highest of ear weight, ear without husk weight, grain weight and 1,000 grain weight, followed by that
the applications of chemical fertilizers containing all major elements equivalent to 2,000 kg/rai of the OMM
which were not different from the application of chemical fertilizer based on soil chemical analysis. However,
comparing yield and yield component of maize grown in the 1st and 2nd crop. It was found that the application
of OMM of 1,000 kg/rai in combination with chemical fertilizers containing all major elements equivalent to
1,000 kg/rai of the OMM increased the ear weight and ear without husk weight. While, grain weight increased
after using chemical fertilizers containing all major elements equivalent to 2,000 kg/rai of the OMM and the
application of OMM of 1,000 kg/rai in combination with chemical fertilizers containing all major elements
equivalent to 1,000 kg/rai of the OMM. After experiment, it was found that the application of chemical
fertilizers containing all major elements equivalent to 2,000 kg/rai of the OMM affected on the lowest of soil
pH which were not different from the application of chemical fertilizers containing all major elements
equivalent to 1,000 kg/rai of the OMM, the application of chemical fertilizer based on soil chemical analysis
and the application of OMM of 1,000 kg/rai in combination with chemical fertilizers containing all major
elements equivalent to 1,000 kg/rai of the OMM. Further, the application of OMM of 2,000 kg/rai affected
on the highest of ECe
, organic matter and exchangeable Na of soil which were not different from the
application of OMM of 1,000 kg/rai.
