Abstract

Ornamental plants have now developed as souvenirs given at a wedding. Requirements for souvenirs, the plants should be tiny, lush, and have much of flowers. So its growth needs to be modified using a growth regulator paclobutrazol. This study aimed to determine the response of angelonia plants to the application of paclobutrazol at several levels of concentration and determine the concentration of paclobutrazol which has the best appearance of angelonia plants. This research method used a randomized block design (RBD) with treatment of 6 levels of paclobutrazol concentration, namely 0 ppm, 30 ppm, 60 ppm, 90 ppm, 120 ppm and 150 ppm with 3 replications. The F test and further tests were carried out an Orthogonal Polynomials. All tests were carried out at the 5% level. The results showed that the application of paclobutrazol at a concentration level of 30-150 ppm, was effective in suppressing the growth rate of angelonia plants in the vegetative phase. This value was proved by the results of the questionnaire that, the highest visual value was obtained at a concentration of 150 ppm. But with the increasing concentration of paclobutrazol, the freshness of  flowers became shorter. Keywords: Angelonia, Concentration, Paclobutrazol

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

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

Spatifilum is classified as a shade plant that can survive in environments with minimal sunlight or shading Spatifilum plants are known to absorb toxins or clean indoor air from pollutants such as benzene and formaldehyde. Efforts to stimulate flowering and the emergence of spatifilum seedlings include using a growth regulator in the form of benzyladenine (BA). The aim of this research was to determine the difference in the effect of residual BA with and without BA on the flowering of spatifilum plants in the second period. Data collection was carried out in August – November 2022 at the Horticulture Greenhouse, Faculty of Agriculture, University of Lampung. This research used a Complete Randomized Block Design (RAKL) with a single treatment. The treatment consisted of 5 BA concentration treatments, namely 0 ppm, 20 ppm two applications, 20 ppm four applications, 40 ppm two applications, and 40 ppm four applications with four repetitions. The data from this research were analyzed using the barlet test and the additivity test was carried out using the Tukey test. Then the data was analyzed using variance (Anara) and orthogonal contrast tests. The results of the research showed that there were significant differences in the variables of increasing the number of seedlings and increasing the number of flowers. BA concentration of 20 ppm was significantly able to increase the number of offspring compared to a concentration of 40 ppm, meanwhile, a concentration of 40 ppm with a frequency of giving 2x significantly increased the number of flowers compared to a frequency of giving 4x

Abstract

Pineapple (Ananas comosus [L.] Merr.) is one type of fruit that has an important role in Indonesia because it is a major export commodity, both in fresh and processed forms such as canned fruit and juice. Therefore, the development of pineapple production is a strategic matter. One of the steps taken to increase pineapple production is through proper and balanced fertilization. The objective of this study was to determine the best fertilizer package that supports the growth of pineapple plants. The research was conducted from November 2022 to March 2023 using a single-factor Randomized Group Design (RAK), consisting of treatments and repeated 4 times.  The treatment packages tested included the dose and interval of fertilization, namely: P0= 200 kg DAP + 200 kg Kiesirite + 300 kg K2SO4 + 50 kg ZA per ha (0, 30 HST), P1= 300 kg DAP + 300 kg Kiesirite + 300 kg K2SO4 + 50 kg ZA per ha (0, 30, 60 HST), P2= 300 kg DAP + 300 kg Kiesirite + 300 kg K2SO4+ 50 kg ZA per ha (0, 15, 45 HST), P3= 350 kg DAP + 350 kg Kiesirite + 350 kg K2SO4 + 50 kg ZA per ha (0, 30, 60 HST), and P4= 350 kg DAP + 350 kg Kiesirite + 350 kg K2SO4 + 100 kg ZA per ha (0, 15, 45 HST). In each experimental unit, 5 sample plants were selected, so that the total plants observed were 100 sample plants. The data were analyzed using analysis of variance, and the F test showed significant differences which were then further tested with the Least Significant Difference (BNT) test at the 5% level.  The results showed that in general, fertilizer doses and intervals had no significant effect on most of the observed variables, except on d-leaf width and d-leaf length.  The fertilizer package in the P0 treatment (200 kg DAP + 200 kg Kiesirite + 300 kg K2SO4 + 50 kg ZA) per ha proved to be the best to support pineapple plant growth. Keywords: dosage, fertilization frequency, pineapple, inorganic fertilizer

Abstract

Pekon Giham Sukamaju termasuk dalam wilayah dataran tinggi di Kecamatan Sekincau Lampung Barat yang cocok untuk usaha pertanian, khususnya tanaman hortikultura. Beberapa petani di Pekon Giham, Sukamaju mulai tertarik  menanam  jeruk  sebagai  komoditas  unggulan baru, tetapi pemahaman dalam budidaya jeruk masih minim dan belum sesuai dengan kaidah GAP (good agricultural practices) untuk dapat menghasilkan panenan yang sehat, bermutu tinggi, dan berdaya saing sehingga mampu meningkatkan  pendapatan  petani.  Pengamatan di lapang menunjukkan  bahwa petani menanam jeruk seadanya terutama dalam pemeliharaan tanaman jeruk meliputi pemupukan dan pemangkasan. Tujuan kegiatan ini adalah (1) memberikan pengetahuan teoritis tentang teknik budidaya jeruk di dataran tinggi menurut kaidah GAP, (2) agar petani mengetahui dan mampu menerapkan teknologi bujangseta pada pertanaman jeruk. Hasil kegiatan menunjukkan bahwa terjadi peningkatan pengetahuan pemeliharaan jeruk dengan penerapan teknologi bujangseta sebesar 43,3%, terutama dalam hal pemangkasan dan pemupukan. Pemahaman dalam praktik penerapan teknologi bujangseta hanya terlihat pada lima orang peserta dari 13 anggota petani jeruk. Ketrampilan teknis budidaya jeruk yang dikuasai terutama pemupukan dan sebagian pemangkasan. Manajemen pengendalian OPT kurang dipaham petani.
