| Summary: | Livestock waste is one of the sources of organic pollutants in surface
and ground water. This entire time, the cattle owners in Dago Atas dispose the
cattle manure directly into Cikapundung River without any treatment. Then it
needs to be implementing a treatment technology to overcome the negative impact
of the wastes disposal and to gain an added-value by recycling the livestock waste
into organic fertilizer products. The solid fertilizers were made by mixing the
manure with 5% Effective Microorganism 4 (EM4) of the total weight of the
mixture, while the liquid fertilizers weremade by adding urine with 10% EM4 of
the total weight of the mixture. To ensure that this technology is appropriate to be
applied, further research is needed in order to investigate the effect of the
fertilization on the plant growth. The fertilizer in this research was implemented
on the mustard greens and the lettuce crops. This research was arranged in a
completely randomized factorial design with two factors: the first is a
combination of the solid fertilizers dose and the second is a combination of the
liquid fertilizer dose. The growth variables measured for each crop are the plant
height per week, amount of leaves, total fresh weight, consume fresh weight,
harvest index, and stem diameter. Based on the ANOVA test was concluded that
the solid fertilizer effect on plant height, number of leaves, stem diameter, total
weight and consume weight of mustard green. While on the lettuce, solid fertilizer
effect on plant height, stem diameter, total weight, and consume weight. The use
of liquid fertilizer had no effect on growth of mustard and lettuce. It was found
from the Duncan test that the best solid fertilizer dose in mustard green and
lettuce is 4 kg/m2. |
