Abstract

Tuberose (Polyanthus tuberosa L.) is a popular ornamental plant in Indonesia as cut flowers and sowing flowers. It can be used as potted flowers by making the flower stalks shorter. One way to get tuberose that have criteria as potted flowers is by administering growth inhibitors using Paclobutrazol. This research was conducted at the Greenhouse of the Horticultural Building, Faculty of Agriculture, University of Lampung in November to August 2017, aimed to determine the effect of the concentration of paclobutrazol on the growth and appearance of tuberose and to determine the best concentration of paclobutrazol in the appearance of potted tuberose. This study used a randomized block design (RCBD) with a single treatment with 6 levels of paclobutrazol concentration, namely 0, 75, 150, 225, 300, and 375 ppm with 3 replications. Homogeneity of variance was tested by Bartlett test and additivity was tested by Tukey test. Then, it was continued with the F test and with the Least Significant Difference test (LSD) at the 5% level. The results showed that administration of paclobutrazol was significantly affected pseudo stem circumference and all variables of generative growth except the length of the florets. The concentration of paclobutrazol up to 375 ppm has not obtained optimum results. Keywords: Concentration, growth, paclobutrazol, tuberose

Abstract

Spatifilum (Spathiphyllum wallisii) is a popular ornamental plant that can be used as indoor decoration, so its appearance should be attractive.  Apart from flowering, an interesting criteria for the appearance of the spatula is to have many tillers so that it looks lush.  One of the efforts to obtain this appearance is the provision of a growth regulator capable of accelerating shoot growth, namely Benzyladenine (BA).  The purpose of this study was to determine the concentration of BA which produced the best effect on spatifylum growth.  This research was conducted in the greenhouse of the Horticulture Building, Faculty of Agriculture, University of Lampung from July 2019 to January 2020.  This research was arranged in a structured single factor treatment design consisting of six BA concentration treatments, namely 0 ppm, 10 ppm, 20 ppm, 30 ppm, 40 ppm, and 50 ppm with six repetitions.  Data analysis used standard deviation which is presented in the form of a histogram by taking the average value of each treatment.  The results showed that the administration of benzyladenine with concentrations 10-50 ppm tended to increase spatifylum growth in the variable leaf area, leaf greenness, tiller emergence, number of tillers, flower emergence time, and number of flowers, but had no effect on the addition of plant height and number of leaves.  Giving benzyladenine with a concentration of 20 ppm was quite efficient in optimizing the vegetatif growth of spatilum, which was shown by the increase in plant height, increased number of leaves, time to emergence of tillers, and number of tillers.  On the other hand, the effect of benziladenine on the generative phase requires a higher concentration, namely at a concentration of 50 ppm, the time for which the flower buds appear is the fastest and the number of flowers is the most.  Keywords:  Benzyladenine, Concentration, and Spatifillum.

Abstract

Shallots (Allium ascalonicum L.) is one of the leading vegetable commodities used as food seasoning and traditional medicine. This study aims to see the effect of providing various doses of NPK fertilizer and types of biological fertilizers on the growth and production of shallot plants. This study used a randomized block design (RAK) arranged in a factorial (4 x 2). The first factor is the NPK fertilizer dosage which consists of four levels, namely: N0= 0% (without NPK fertilizer), N1= 50% (25 g/m2), N2= 100% (50 g/m2), and N3= 150% (75 g/m2). The second factor is the type of biological fertilizer which consists of two levels, namely: H1= Grikulan plus fertilizer and H2= EM4. The results showed that the NPK fertilizer dosage treatment up to a dose of 75g/m2 gave the best results on plant growth and development, including the number of leaves, plant height, fresh tuber weight per plant, wind dry tuber weight per plant, and wind dry tuber weight per m2. The growth and development of shallot plants with the application of Grikulan biological fertilizers were better than those of EM4 biological fertilizers. Treatment of NPK fertilizer dosage of 150% or equivalent to 75 g / m2 supplemented with the application of Grikulan plus fertilizer results in higher production, namely the weight of dry tubers per m2 reaching 1674.33 g or equivalent to 11.72 tonnes/ha. Keywords : EM4, Grikulan plus, shallots,NPK, yield

Abstract

Rendahnya produksi bawang merah di Indonesia disebabkan salah satunya oleh penyakit moler (Fusarium oxysporum). Penelitian ini bertujuan untuk mengetahui pengaruh pemberian pupuk hayati dan pupuk kandang terhadap intensitas penyakit moler, mengetahui pengaruh pemberian pupuk hayati dan pupuk kandang terhadap produksi bawang merah, dan mengetahui interaksi dari pupuk hayati dan pupuk kandang terhadap intensitas penyakit moler dan produksi bawang merah. Penelitian ini dilaksanakan di Laboratorium Ilmu Penyakit Tanaman, Fakultas Pertanian dan Laboratorium Lapang Terpadu Fakultas Pertanian Universitas Lampung pada November 2019 sampai dengan Februari 2020. Penelitian ini disusun menggunakan Rancangan Acak Kelompok (RAK) dengan 8 perlakuan dan 3 ulangan. Delapan perlakuan tersebut adalah tanpa pupuk hayati dan tanpa pupuk kandang (P0K0), tanpa pupuk hayati+pupuk kandang ayam (P0K1), tanpa pupuk hayati+pupuk kandang kambing (P0K2), tanpa pupuk hayati+pupuk kandang sapi(P0K3), pupuk hayati 10 ml/l+tanpa pupuk kandang (P1K0), pupuk hayati 10 ml/l+pupuk kandang ayam (P1K1), pupuk hayati 10 ml/l+pupuk kandang kambing (P1K2), dan pupuk hayati 10 ml/l+pupuk kandang sapi (P1K3). Hasil penelitian menunjukkan bahwa pemberian pupuk hayati dan pupuk kandang mampu menekan intensitas penyakit moler dengan P1K2 36% pada 4 MST dan 5,3% pada 6 MST pada keterjadian penyakit sedangkan pada keparahan penyakit P1K2 7,2% pada 4 MST dan 1,1% pada 6 MST. Pemberian pupuk hayati dan pupuk kandang menunjukkan bahwa tidak berbeda nyata pada variabel bobot tanaman umbi basah dan kering angin. Hal tersebut diduga karena tanaman tidak maksimal menyerap unsur hara dan tidak ada pemberian pupuk kimia.

Abstract

Low production of red chili (Capsicum annuum L.) remains a major constraint in meeting market demand and is frequently attributed to suboptimal soil fertility. Enhancing soil fertility through appropriate fertilization strategies, including both chemical and organic inputs, is therefore critical to improving crop yield. In addition, microbial consortia with plant growth-promoting potential are increasingly explored as biofertilizer alternatives to support sustainable agriculture. This study investigated the effects of selected bacterial isolate consortia, types of fertilizers, and their interactions on the growth and production of red chili plants. A 4 × 3 factorial Randomized Group Design with three replications was employed. The first factor was the bacterial consortium: no consortium (K0), consortium from pineapple rhizosphere (PR) (K1), consortium from Empty Fruit Bunches (EFB) (K2), and a combination of PR + EFB (K3). The second factor was fertilizer type: chemical fertilizer (P1), sterile organonitrophos fertilizer (P2), and non-sterile organonitrophos fertilizer (P3). The results indicated that the application of bacterial isolate consortia did not significantly influence red chili growth or production. However, sterile organonitrophos fertilizer enhanced chili production, while non-sterile organonitrophos fertilizer produced the best outcomes for plant growth and soil organic-C content. No significant interaction was observed between bacterial consortia and fertilizer type for any measured parameter. These findings underscore the greater role of organic-based fertilizers, particularly non-sterile organonitrophos, in improving soil quality and crop performance, thereby offering a sustainable alternative to chemical fertilization for red chili cultivation.
