Abstract:
Rice is the staple food of most Indonesians. Rice production in Indonesia cannot be separated
from inorganic fertilizers which have a bad impact on the environment, so it is necessary to
carry out a revolution, one of which is the System of Rice Intensification (SRI) method. The
addition of FAA organic matter originating from fish sorted by fishermen which have no
selling price was used as a substitute for inorganic fertilizers. This study aimseds to
determine the effect of FAA application on growth and N uptake in rice plants using the SRI
method and to determine the best dose. This research was conducted in December 2019 -
April 2020 at a greenhouse in Agroecotechnology Department, Faculty of Agriculture,
Lambung Mangkurat University, Banjarbaru. The design used was a one-factor Completely
Randomized Design (CRD), with treatment f0 (0 mL FAA L-1 / control), f1 (1 mL FAA L-1),
f2 (3 mL FAA L-1), f3 (5 mL FAA L-1), and f4 (7 mL FAA L-1). The treatment was repeated
five times, to obtain 25 experimental units. Observation parameters in the study were plant
height, number of tillers, and N uptake of rice leaves. The results showed that the application
of FAA with a dose of 1 mL FAA L-1 was able to increase the height of rice plants by 5.5%,
produced an average number of tillers by 14, and was able to increase N-uptake by 9.6% in
rice plant leaves.
Keywords: liquid organic fertilizer, wetland, sub-optimal, N uptake.
