Pakcoy (Brassica rapa L.) is a type of vegetable plant is used by people in various dishes because it contains minerals, protein, Vitamin A, Vitamin B, Vitamin B2, Vitamin B6, Vitamin C, potassium, phosphorus, copper, magnesium, iron, carbohydrates and fiber.This research aims to see the effect of giving POC and chicken manure on the growth and production of pakcoy plants. This research was carried out using a factorial Randomized Block Design (RAK) which consisted of two factors, namely the concentration of chicken manure which consisted of 3 levels, namely A0 = 0 kg / plot, A1 = 1 kg / plot, A2 = 2 kg / plot, and A3 = 3 kg / plot. The second factor is the POC dose which consists of 4 levels, namely. E1=10 ml/liter water/m2, E2= 20 ml/liter water/m2 and E3=30 ml/liter water/m2. The results showed that the application of chicken manure had no significant effect on the number of leaves, wet harvest weight per plot, wet harvest weight per hectare, wet sale weight per hectare. The interaction between giving chicken manure and POC had a significant effect on the number of leaves, wet weight of harvest per plot, wet weight of harvest per hectare, wet weight of sale per hectare.

This research was conducted in Barus Jahe Village, Barus Jahe District, Karo Regency, North Sumatra, with an altitude of 1,367 meters above sea level. This study aims to determine the effect of the composition of the planting medium and several varieties on the production and growth of strawberry plants. The design used in this research is a Factorial Split Plot Design (RPT), which consists of two factors. The first factor is the main plot, Variety (V), with 3 levels: V1 = California, V2 = Local Bandung, and V3 = Local Brastagi. The second factor is the subplot, namely Planting Media Composition (M), which consists of Soil: Charcoal Husk: Chicken Manure, namely: M1= 1:1:1, M2= 2:1:1, M3= 1:2:1, and M4= 2:1:2.The variables observed were plant height, plant wet weight and plant dry weight, fruit weight and sugar content (Brix). Analysis of variance was used to test the effect of treatment and mean differences between treatments; honest significant difference tests, regression, and correlation were carried out at a test level of 5%. The research results showed that the composition of the planting media had no significant effect on the observed parameters. However, in some varieties, V1 (California) has a substantial impact on fruit weight and sugar content (Brix), and V2 (Local Bandung) has a significant effect on plant height, wet weight, and dry weight.

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.

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.

Dormancy is a state of stopping growth experienced by plants. This research aimed to determine the concentration of KNO3 solution in breaking dormancy in several papaya varieties. The research method used in this research was a completely randomized design (RAL) Factorial with 2 treatment factors. The first factor is variety (V), consisting of V1 = Callina, V2 = California, and V3 = Local. The second factor is the concentration of the KNO3 (K) solution consisting of: K0 = Control, K1 = 10%, K2 = 20% and K3 = 30%. The variables observed were growth synchrony and germination speed index. Data analysis uses analysis of variance. The variables observed were growth synchrony and germination speed index. An analysis of variance was used to test the effect of treatment. To test mean differences between treatments, honest significant difference tests, regression, and correlation were carried out at a test level of 5%. The research results showed that seed variety had a significant effect on growth synchrony and germination speed index. The concentration of KNO3 solution has a significant effect on growth synchrony and germination speed index. The interaction between the variety and concentration of KNO3 solution had no significant effect on all observed parameters.

The purpose of this study was to determine the effect of urea fertilizer and organic manure derived from goat manure on the growth of oil palm seedlings in the pre-nursery stage. The research was conducted using a factorial Randomized Complete Block Design (RCBD) consisting of two factors. The first factor was urea fertilizer treatment with three levels: U0 = control, U1 = 3 g/polybag, and U2 = 6 g/polybag. The second factor was the dose of goat manure (K) with three levels: K1 = control, K2 = 200 g/polybag, and K3 = 400 g/polybag. The interaction between urea and goat manure doses had a significant effect on plant height, stem diameter, number of leaves, leaf length, leaf width, and leaf area.
