Abstract

The Saga plant (Adhenanthera pavonina L) is a plant that can be used in all parts of the plant, from seeds, wood, bark, stems and leaves. To support the growth of saga seedlings, planting media is needed that contains sufficient nutrients. Providing organic fertilizer can improve the physical, chemical and biological properties of the soil, and can increase the availability of nutrients in the soil. This research was carried out for three months, namely March to June 2023, at the Arboretum Nursery of the Faculty of Forestry, Tadulako University. This research used a Completely Randomized Design (RAL) method with 3 treatments and 7 replications so there were 21 research units. The treatments given were P0= Control, P1=Lamtoro Fertilizer 100 gr/polybag, P2=Lamtoro Fertilizer 150 gr/polybag. Observation parameters were seedling height, stem diameter, and number of leaves. Data were analyzed using analysis of variance (F test). If based on the analysis of variance (F test) there is a significant effect, then the Least Significant Difference (BNT) test is continued at the 5% level. The results of the research showed that treatment with various doses of lamtoro leaf organic fertilizer on ex-mining planting media had a significant effect on the increase in height, diameter and number of leaves on saga seedlings (Adhenanthera pavonina L.). Based on the results of the 5% significant difference test (BNJ), it shows that the average increase in height and diameter of saga seedlings in treatment P2 is significantly different from treatments P1 and P0, but the average leaf growth in treatment P2 is not significantly different. significantly different. significantly different from P1, but significantly different. against P0. The average height increase results are P2=7.4, P1=5.3, P0=2.9. Average increase in diameter P2=2.24mm, P1=0.9mm, P0=0.6mm. The average increase in number of leaves was P2=22.42, P1=20.17 and P0=8.71.

Abstract

This research was carried out for two months, from July to September 2023 located at the Arboretum of the Faculty of Forestry, Tadulako University, Palu, Central Sulawesi. This study used the Complete Randomized Design (RAL) method, consisting of Five Treatments M0 = Soil Without POC (control), M1 = Concentration 45% (450ml POC + 550ml water), M2 = Concentration 50% (500ml POC + 500ml water), M3 = Concentration 55% (550ml POC + 450ml water), M4 = Concentration 60% (600ml POC + 400ml water) Of the five treatments repeated 6 times each, so that a total of thirty (30) treatment samples were used. The parameters observed in this study were the increase in seedling height, the increase in the number of leaves, and the increase in stem diameter. The research data was analyzed using fingerprint analysis. Further tests were carried out using the Real Difference Test (BNJ) at the level of 5%. The results of fingerprint analysis show that the application of various concentrations of liquid organic fertilizer made from oil palm tangkos has a significant effect on the increase in seedling height, number of leaves, and stem diameter in the field. The 55% concentration treatment (M3) gave the best effect with an average height increase of 8.25cm, an increase in the number of leaves by 2.5 strands and an increase in stem diameter by 1.81mm.
