Abstract

The need for curly red chili plants for nutrients can be met with appropriate fertilization according to the needs of the plant itself, fertilization aims to improve plant fertility to plant growth. The purpose of this study was to determine the effect of npk16-16-16 fertilizer and application time on red chili plant growth. The research was conducted in Afdeling 2 plantation area, West Bila Subdistrict, Labuhanbatu Regency. This research was carried out from October 2021 to February 2022. The design used in this study was a randomized block design (RAK) and used a 3x3 factorial consisting of 2 factors. The first factor was the application of NPK 16 16 16 fertilizer with 3 levels, P1: a dose of 3 g/plant, P2: a dose of 6 g/plant, P3: a dose of 9 g/plant. The second factor is the application time of NPK 16-16-16 fertilizer with 3 levels, K1: once a week, K2: once every 2 weeks, K3: once every 3 weeks. Observational data were analyzed with a 5% level of variance to determine whether there was a significant difference between treatments. Followed by Duncan's New Multiple Range Test (DMRT) level 5% if there is a significant difference in each treatment. The results showed that the treatment at a dose of 9 g/plant gave a good trend in plant height growth. while the dose of 6 g/plant gave a tendency of good yields in all yields and several observations of the growth of flowering age and leaf area.

Abstract

The internship activity at PT Supra Matra Abadi Kebun Aek Nabara (KAN) in Bilah Hulu District, LabuhanBatu Regency, North Sumatra Province, this activity was carried out for four months, March-July and the method used was a completely randomized design (CRD) with 2 different treatments, namely by concentration of 6% and 7%. Results: Afdilling III PT Supra Matra Abadi controlled banyan weeds using two treatments, namely manually and chemically. The banyan weed is a nuisance plant, because its life clings to or suffocates the oil palm plant. The negative impacts on oil palm plants are pest attacks, competition occurs, humidity increases, making it difficult for the pruning and harvesting processes. The banyan weed population in PT Supra Matra Abadi is in block C87C and block C87G. The purpose of this study was to determine the effective and efficient concentration in the use of the supremo herbicide with the active ingredient glyphosate. Based on the results of research that has been carried out from the two concentrations of the herbicide supremo 480 SL which is effective and efficient for controlling banyan weeds in oil palm plants, namely a concentration of 7%. Because at a concentration of 6% it takes 30 days to see the banyan weed die

Abstract

The mainstay commodity that can be expected to increase the income and dignity of plantation farmers and Indonesian transmigrants is Palm Oil (Elaeis Guinensis Jacq). Oil palm Soil microbes have an important role in the soil ecosystem which is responsible for the nutrient cycle to maintain soil fertility and structure, especially the biological properties of the soil. This research was carried out through 2 stages of activities, namely field activities and analysis activities. Stages of field activities were carried out at the Kebun Sinar Pandawa Palm Oil Plantation PT. Sinar Pandawa, Labuhanabtu, North Sumatra Province with a height of 28 meters. The method used in this research is a free grid measurement method at a semi-detailed survey level (observation frequency of 1 sample per 500 meters). Carrying out soil sampling at up to 5 sampling points with a distance of 100 meters in the field using a random method, spread over a predetermined area based on the base map. Research Results Land use with different vegetation produces different biological and chemical soil properties. Soil organic C was positively correlated with total microbial population, total fungal population, and respiration. The highest correlation between biological and chemical soil properties was obtained from the total microbial population with a total P of 0.714. The highest correlation was obtained from the correlation between organic C and total N levels, namely 0.947.

Abstract

The purpose of this research is to survey and mapping nutrient status of total phosphate, available phosphate, soil pH and organic carbon at paddy fields Meijan Village Balige District Toba Regency and its influence on rice production. Soil samples was analyzed at the Analytical Laboratory of PT Socfindo Indonesia North Sumatera Province. Which began in October to December 2023 The method used is Free Grid Survey semidetailed level survey and analysis of nutrient data total phospate by Acid destruction method (HClO4), available phosphate by Bray II method, soil pH by H2O extraction and organic carbon by walkley & black method and then interpret to the map nutrient status. The result of research showing that status total phosphate classified by 3 status such as, medium (81,59 ha), high (81,15 ha) and very high (27,26 ha). Available phosphate classified in 3 nutrient status such as very low (39,11 ha), low (137,40 ha) and medium (13,49 ha). Soil pH classified in 2 status such as moderately acidic (30,16 ha) and strongly acidic (159,84 ha). Organic carbon classified by 3 nutrient status such as very low (3,06 ha), low (135,84 ha) and medium (51,10 ha). Available phosphate and organik carbon affect rice production in Meijan Village Balige District Toba Regency.
