Abstract

A planting medium that rich in nutrients is needed for oil palm, especially in the nursery phase. This study aimed to determine the effect of various doses of EM4 and to get the best dose of EM4 on the growth of oil palm seedlings in the pre-nursery. The research method used was a non-factorial completely randomized design with 4 treatments, namely 0 ml EM4 (A1), 4 ml EM4 (A2), 8 ml EM4 (A3), and 12 ml EM4 (A4). Each treatment was repeated 6 times so that there were 24 experimental units. The data obtained were analyzed for variance at the 5% level, if the effect was real, it was followed by the least significant difference (LSD) test. Based on the results of the study, it could be concluded that application of various EM4 doses had a significant effect on plant height (4-12 MST), the number of leaves (4-8 MST), trunk girth (4-12 MST), and shoot wet weight but did not significantly affect the number of leaves (12 MST), the volume of roots, length of roots, root wet weight and shoot dry weight, dry weight root, the best dose was shown at a dose of 12 ml EM4.

Abstract

Pakcoy is a vegetable commodity that has high economic value. This study aims to determine the effect of humic acid and Trichoderma sp. by utilizing empty fruit bunch (EFB) waste as a growing medium for Pakcoy growth. The research method used was a two-factor randomized block design. The first factor is humic acid (AH) with three levels: AH1 = 1 g, AH2 = 2 g, AH3 = 3 g. The second factor is Trichoderma sp. (T) with three levels; T1 = 50 ml, T2 = 100 ml, T3 = 150 ml. In this study it was concluded, the best treatment was found in the application of humic acid with a dose of 1 g on the parameters of observation of leaf length, leaf width, plant height, wet weight, and plant dry weight. The use of Trichoderma sp. in this study, does not affect all parameters observation. The results of the analysis of the planting medium showed that the pH was slightly acidic conditions 5.67 - 6.33. The organic matter content contained in the growing media ranged from 1.20 to 2.62%, and the total N-total contained in the growing medium ranged from 0.10 to 0.18. In-plant tissue analysis shows that the N-total found in plant tissue ranges from 4.62 - 5.23.
