Effect of Fish Amino Acid Application on Growth and N-uptake in Plants Rice Using The System of Rice Intensification Method

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.
