Abstract

The aim of this research was to determine the response of oil palm seedlings in pre nursery to Urea and Goat Manure treatment. This research used a factorial Randomized Block Design consisting of the first factor, Urea treatment with 3 levels, namely: U0 = 0 g/polybag, U1 = 3 g/polybag and U2 = 6 g/polybag. The second factor is the dose of Goat Manure (K) with 3 treatment levels, namely: K1 = 0 g/polybag, K2 = 200 g/polybag and K3 = 400 g/polybag. The results showed that fertilization with urea 6 g/polybag significantly increased plant height, stem diameter, number of leaves, leaf length, leaf width and leaf area. Treatment with a dose of Goat Manure at a dose of 400 g/polybag significantly increased the growth of plant height, stem diameter, number of leaves, leaf length, leaf width and leaf area. The combination between Urea and the dose of Goat Manure has a significant effect on plant height, stem diameter, number of leaves, leaf length, leaf width and leaf area.

Abstract

Background and Objective: The utilization of cow manure and Phonska fertilizer can yield various impacts on the growth of oil palm seedlings in the pre-nursery, encompassing aspects such as nutrition, soil conditions, root development, plant response, and seedling productivity. This study aims to assess the influence of cow manure and Phonska fertilizer, both individually and in combination, on the growth of oil palm seedlings. Materials and Methods: The research site was located 25 meters above sea level. The study was conducted from April to June 2022. A factorial Randomized Block Design (RBD) with 2 treatment factors was employed. The first factor was the application of cow manure with 3 levels: S1 = 30 g/polybag, S2 = 60 g/polybag, and S3 = 90 g/polybag. The second factor was the application of Phonska Fertilizer (P), with the following levels: P1 = 7 g/polybag, P2 = 14 g/polybag, and P3 = 21 g/polybag. Results: The findings indicated that the application of either cow manure or Phonska significantly impacted plant height, stem diameter, leaf length, leaf width, number of leaves, and leaf area, although the combined treatment did not yield a significant effect. Conclusion: Higher application rates of cow manure or Phonska resulted in increased growth of oil palm seedlings in the pre-nursery, following a linear regression pattern.

The Effect of ZA and Growtone on increasing Growth of Mas Kirana Banana Superior Variety (Musa Acuminata L.) from Tissue Culture Results at Screen House. The aim of study was to determine the effect of Growtone and ZA on increasing the growth of mas Kirana banana seedlings (Musa acummunata L.) at the acclimatization stage. This study used a Completely Randomized Design (CRD) factorial with 2 treatments. The first factor of Growtone (A) consists of 3 levels, namely A0 = Control, A1 = 50 mg/100 ml water/plant, A2 = 100 mg/100 ml water/plant. The second factor is ZA (Z) consisting of 3 levels namely: Z0 = control, Z1 = 0.5 g/plant, Z2 = 1 g/plant. The results showed that the Growtone treatment had a significant effect on the increase in plant height, the increase in the number of leaves, the increase in leaf width, root volume, but not significant on wet weight and shoot dry weight. The ZA treatment also had significant effect on the increase in plant height, the increase in the number of leaves, the increase in leaf width, root volume but no significant effect on wet weight and shoot dry weight. The effect of the combination of Growtone and ZA treatments was not significant on all observed variables.

Abstract

Oil palm is a mayor commodity crop in Indonesia. This study aims to analyze the effects of NPK fertilizer and Biotrent Sawit liquid organic fertilizer on the growth of oil palm seedlings in a pre-nursery. The research was conducted on Jalan Biola No. 17 Medan, from April to July 2024. A factorial Completely Randomized Design (CRD) was used, with two factors: the first being NPK fertilizer (Phonska) at three levels-P0 = control, P1 = 1.5 g/seedling, and P2 = 3.0 g/seedling; the second factor was the liquid organic fertilizer Biotrent Sawit, applied at three levels-B1 = 1 cc/seedling, B2 = 2 cc/seedling, and B3 = 3 cc/seedling. The variables observed included seedling height, number of leaves, leaf length, leaf width, leaf area, and root volume. The results showed that the NPK (Phonska) fertilizer and Biotrent Sawit liquid organic fertilizer treatments had significant effects on Seedling Height, Leaf Length, Leaf Width, Leaf Area, and Root Volume. However, Treatment had no significant effect on the Number of Leaves in oil palm seedlings. Until the end of the observation period, there was no significant interaction between NPK (Phonska) and Biotrent Sawit liquid organic fertilizer. Generally, higher doses of NPK (Phonska) and Biotrent Sawit liquid organic fertilizer enhanced the growth of oil palm seedlings.
