PENGARUH BERBAGAI KONSENTRASI POC DAUN LAMTORO DAN INTERVAL PEMBERIAN TERHADAP PERTUMBUHAN DAN HASIL TANAMAN SAWI HIJAU (Brassica juncea L.)

This study aims to determine the effect of lamtoro leaf POC on mustard plants carried out in Mawang Village, Somba Opu District, Gowa Regency from October 2022 to January 2023. This study used a two-factor factorial pattern of group randomised design (RAK), namely the concentration of lamtoro leaf liquid fertiliser and the time interval for applying lamtoro leaf organic fertiliser. The parameters observed were plant height, number of leaves, leaf area, mustard consumption weight, mustard dry weight, mustard root wet weight, and mustard root dry weight. The results of this study showed that the interaction between the concentration of lamtoro leaf POC and the time interval of application did not show a significant effect on the growth and yield of mustard greens. Application of lamtoro leaf liquid organic fertiliser with a concentration of 30% gave the best effect on the parameters of plant height which was 24.4 cm, number of leaves which was 8.83 strands, leaf area 74, wet weight of consumption which was 14.48 g, and dry weight of consumption which was 1.14 g. The time interval of application of lamtoro leaf liquid organic fertiliser with a concentration of 30% gave the best effect on the parameters of plant height which was 24.4 cm. The time interval of applying lamtoro leaf liquid organic fertiliser every 6 days gave the best effect with plant height of 26.59 cm, number of leaves of 9 strands, leaf area of 83.11, wet weight of consumption of 16.28, dry weight of consumption of 1.27g, wet weight of roots of 2.36 g, dry weight of plant roots of 0.51 grams.
