Abstract

Pineapple (Ananas comosus [L.] Merr) is one of the potential horticultural commodities and is a mainstay of exports in Indonesia.  Pineapple fruit productivity can be increased through the fertilization process. One of the fertilization processes in pineapple plants is fertilization after forcing.  The nutrients needed by pineapple plants after forcing are nitrogen and potassium which can support plant growth and increase pineapple fruit production. The purpose of this study was to determine the effect of the frequency of fertilization after forcing and to find out which treatment had the highest productivity. The research was conducted from October 2022 to April 2023 at the Central Lampung Pineapple Plantation, Lampung Province. This study used a single factor randomized block design (RBD), namely the frequency of fertilization on the day after forcing (HSF). The treatment consisted of four levels, namely twice fertilization given at 20 and 55 HSF (P1), two times fertilization given at 15 and 30 HSF (P2), three times fertilization given at 15, 30, 45 HSF (P3) and four times of fertilization given at 15, 30, 45, 60 HSF (P4). Each fertilization application uses Urea 50 kg/ha and K2SO4 75 kg/ha. Each treatment was repeated four times to obtain 16 experimental units. The results showed that the frequency of fertilization after forcing had an effect on the weight of 12 eyed fruit, the length of 11 and 12 eyed fruit, the diameter of 12 eyed fruit, and the weight of 12 eyed crowns in pineapple plants. The fertilization that was able to produce the best pineapple fruit productivity was fertilization with twice the frequency at 15 HSF and 30 HSF which produced the highest production potential compared to the control treatment with a difference of 2.51%.Keywords : pineapple, fertilization, HSF (Days After Forcing)

Abstract

The oil palm plant which has the Latin name Elaeis guineensis Jacq. is one of the main plantation commodities in Indonesia. The growth of weeds on oil palm cultivation land causes competition for growth facilities and affects the growth of oil palm plants (TBM). One of the active ingredients of herbicides used to control weeds in TBM oil palm plantations is metsulfuron methyl herbicide. This study aims to determine the effective dose of 20% metsulfuron methyl herbicide in suppressing weed growth in TBM oil palm plants, to determine changes in the composition of weed species that grow after the application of metsulfuron methyl herbicide, to determine the effect of phytotoxicity on TBM oil palm plants due to herbicide application. This research was conducted in an oil palm plantation in Braja Lebah Village, Braja Selebah District, East Lampung Regency and the Laboratory of Weed Science, Faculty of Agriculture, University of Lampung from August to December 2022. This study used a Randomized Block Design (RAK) with 6 treatments 6 and 4 replications with metsulfuron methyl dose as follows 15; 20; 25; 30g/ha; mechanical weeding and control. The homogeneity of the variance of the data was tested by Barlett's test and the additivity of the data was tested by using the Tukey test and the difference in the mean treatment was tested by the Least Significant Difference (LSD) test at the 5% level. The research results show that; (1) The herbicide methyl metsulfuron 20% at a dose of 15 – 30 g/ha is effective in controlling the growth of total weeds, the dominant weeds Asystasia gangetica and Praxelis climatidea, Boreria alata, Melastoma malabathricum and Richardia brasiliensis up to 12 MSA; (2) Metsulfuron Methyl Herbicide 20% at a dose of 15 – 30 g/ha caused a change in weed composition at 4, 8, and 12 MSA; (3) The application of 20% metsulfuron methyl herbicide at a dose of 15–30 g/ha does not cause poisoning in TBM oil palm plants. Keywords : efficacy, herbicide, oil palm, metsulfuron methyl

Abstract

Coffee is a leading commodity in Indonesia because it can increase people's income and foreign exchange. Coffee production can be affected by flowering. Flowering can be done by giving flower inducer, a flower inducer solution containing nutrients and Sitokinin. This study aims to investigate the influence of concentration and timing of flower inducer solution application on the flowering of robusta coffee plants. The research was conducted in Petaling Banjar Village, Bangka Regency, from January to May 2023, using a split-plot experimental design with a randomized block design, repeated four times. The main plots were the weekly and bi-weekly time intervals, and the subplots were the concentrations of Flower Inducer, namely 0 ml/liter, 10 ml/liter, 20 ml/liter, and 30 ml/liter. The results showed that the concentration of flower inducing solution significantly increased the number of silver primordia, the number of perfasciculus primordia, and the period of primordia emergence. A concentration of 20 ml/liter is the best concentration that induces coffee primordia and flowers. Keywords : Coffee, flowering, concentration, sitokinin

Abstract

Increasing the production of pineapple fruit can be done by manipulating the plant using Gibberellic Acid Growth Regulatory Substance (ZPT).  The purpose of this study was to determine the effect of GA3 concentration and application method, as well as its interaction in increasing the vegetative growth of pineapple plants.  Data collection was carried out in November 2022- February 2023 at a pineapple plantation company in Central Lampung. Treatments were arranged factorial (3x2) using a randomized block design with 3 replications. The first factor was Gibberellin (A) which consisted of three levels, (A1) 0 ppm GA3, (A2) 200 ppm GA3, and (A3) 400 ppm GA3.  The second factor is the application method (B) which consists of 2 levels, namely (B1) Application on the top of the leaf (B2) Application on the bottom of the leaf. The observed variables included plant height, stem diameter, number of leaves, D-leaf length, D-leaf width, number of roots, root length, fresh weight of roots, fresh weight of plants. Homogeneity of variance between treatments was tested by Barlett's test and additivity using Tukey's test and then analysis of variance was carried out.  Separation of the mean was carried out using the least significant difference test (LSD) at the 5% level. The results showed that 400 ppm GA3 was better than the control in affecting plant fresh weight with a difference of 630,7 g, the treatment of the application method on the leaves was better than the bottom leaf in affecting plant fresh weight with a difference 201,4 g. Treatment with a concentration of 40 ppm using the leaf application method was better than the control treatment. It is suggested to do further research related to the effect of giving GA3 on the generative phase of pineapple plants.Keywords : Gibberellic Acid, application method, pinneaple

Abstract

One of the efforts to control weeds in preparing land for lowland rice cultivation with the No-Tillage system one of which uses isopropylamineglyphosate herbicide. The purpose of this study was to determine the dose of glyphosate herbicide that effectively controls weeds for preparation of lowland rice planting with the no tillage system, to determine changes in weed composition in lowland rice after the application of glyphosate herbicide, and to determine the effect of the no tillage system after the application of glyphosate herbicide on growth and paddy yields. Data collection was carried out from June to September 2022 in the rice fields of Trimurjo District, Central Lampung Regency and the Weed Science Laboratory, Faculty of Agriculture, University of Lampung. The treatment was arranged using a randomized block design with 4 replications and 6 treatments consisting of the glyphosate herbicide doses (1,080; 1,440; 1,800; 2,160 g/ha) + no tillage, manual weeding, and intensive tillage system. Homogeneity of variance was tested by Barlett's test and then analyzed for variance. Separation of the mean was carried out using the least significant difference test (LSD) at the 5% level. The results showed that the herbicide isopropylamine glyphosate doses of 1,800 and 2,160 g/ha of the no tillage system could be used to replace the intensive tillage system because it was effective in controlling total weeds, sedges, grasses, and broad leaf groups, dominant weed Fimbristylis miliacea, Echinochloa colonum, Ludwigia octovalvis and Monochoria vaginalis up to 6 WAP, causing a change in the composition of weed species from Echinochloa colonum become monochoria vaginalis at 3 WAP, and from Echinochloa colonum become Ludwigia octovalvis at 6 WAP. The growth  is not stunted and yield of lowland rice plants is equivalent to the intensive tillage system with grain yields per hectare of 5.14 - 5.49 t/ha. Key words : weeds, isopropylamine glyphosate, paddy field, no tillage

Abstract

Pakcoy (Brassica rapa L.) is one of the important and popular vegetable crops in Indonesia. City development and massive urbanization have resulted in the shrinking of agricultural land in urban areas. Home gardens have great potential if managed optimally and planned. Therefore, the concept of urban farming with the vertical farming method can be a solution. This study aimed to determine the optimal composition of planting media and liquid organic fertilizer (LOF) concentration for the growth and production of pakcoy plants. This study used a completely randomized design (CRD) with two factors. The first factor was the composition of the planting medium, which consisted of three levels: soil, compost, and goat manure with a ratio of 1:1:1, 1:1:2, and 1:2:1. The second factor was the concentration of LOF and urea, which consisted of four levels: 1 gram urea, 2 ml/liter water, 4 ml/liter water, and 6 ml/liter water. The results of the study showed that the combination of planting medium composition and LOF concentration had an effect on all observation parameters. The combination of planting medium composition 1:1:2 and LOF concentration of 4 ml/liter water produced the best results for all observation parameters, namely plant height, number of leaves, total fresh weight, fresh head weight, fresh root weight, and plant dry weight. Key words : Pakcoy mustard, verticulture, media composition, concentration, LOF
