Abstract

The problem in patchouli plant cultivation is the reduction of soil?s fertility level which effects on the decreasing of plant growth and yield.  Application of cattle manure is a key to increase the soil?s productivity. The objective of this research is to study the effect of application method and cattle manure dosage on plant growth and yield of patchouli plant. This research was conducted at Lampung Agriculture Polytechnic research?s field in Hajimena Bandar Lampung from December 2010 to March 2011. The experiment was factorial designed (2 X 4 factors) with randomized completely block design with three replications. The first factor was manure cattle application method: spreaded on soil surface or mixed with top soil. The second factor was manure cattle dosage, consist of 0, 10, 20, and 30 ton/ha.  Result showed that (1) the application of manure cattle increased the growth and yield of patchouli plant; the increasing of the dosage would increase plant growth and yield of patchouli plant, (2) Patchouli plant which applied with cattle manure that mixed with top soil has longer primary root, (3) There is no interaction effect between application method and manure cattle dosage on plant growth and yield of patchouli plant.  Key words: application method, cattle manure, growth, yield, Pogostemon cablin

Abstract

To get high quality physic nut seedling one of effort is with vegetative propagation especially with grafting. The objective of this study was to evaluate the effect the maturity of rootstocks and shading rate on the effectiveness of grafting and the growth of seedling of Jatropka. The experiment was conducted in Labuhan Dalam, Subdistrict Tanjung Seneng, the City of Bandar Lampung from January-June 2008. Is a factorial experiment (3X4) with split plot design, shading degrees as main plot consisted without shading, light shading, moderate shading, and heavy shading. Root stock age as subplot consisted 6, 8, and 10 weeks after transplanting. The treatments were consisted 3 replication and each experiment unit consisted 10 seedlings. The result shows that root stock age 8 and 10 weeks produces physic nut seedling growth better than root stock age 6 week. Physic nut seedling without shading and light shading (1 layer paranet) grow better than with moderate shading (2 layers paranet) and heavy shading (3 layers paranet);Key words: Physic nut, root stock age, shading

Abstract

Pepper plant propagation generally uses stem cuttings. Choosing the maturity level of the cutting will determine the subsequent growth of the cutting, because the body parts of the plant contain different food reserves and endogenous auxin. The growth regulator Indole Acetic Acid is used to stimulate the growth of roots and shoots of cuttings. The research aims to determine the effect of the level of maturity of the cutting material and IAA concentration on the growth of pepper seedlings and to determine the effect of the interaction between the two treatments. Research was carried out in the Greenhouse and Plant Science Laboratory, Faculty of Agriculture, University of Lampung. The experimental design used a completely randomized design (RTS), homogeneity was tested with the Bartlett test, non-additivity was tested with the Tukey test. Analysis of variance and least significant difference test (LSL) were carried out at the 5% level. The research results concluded (1). Cuttings originating from the middle part grew faster, namely in sprouting shoots, length of cutting shoots, number of leaves, and dry weight, but there was no significant difference in the dry weight of cutting roots. (2). An IAA concentration of 500 ppm gave the best response to shoot sprouting, shoot length of cuttings, number of leaves, and root dry weight. (3). Cuttings originating from the middle section that were applied with IAA 500 ppm were the best combination in terms of shoot emergence, shoot length, number of leaves, and shoot dry weight. Key words: cuttings, indole acetic acid, black pepper

Abstract

Produksi fungi mikoriza arbuskular sangat dipengaruhi oleh media tanam dan tanaman inang. Oleh karena itu penelitian ini bertujuan untuk mendapatkan volume media tanam dan jumlah tanaman inang yang terbaik untuk memproduksi spora fungi mikoriza arbuskular (FMA). Penelitian menggunakan rancangan faktorial 5x 5 dengan faktor pertama volume media tanam yang terdiri dari 200 ml, 400 ml, 600 ml, 800 ml, dan 1000 ml. Sedangkan faktor ke dua adalah jumlah tanaman inang per pot yang terdiri dari 1, 2, 3, 4, dan 5 tanaman. Setiap perlakuan diulang sebanyak 4 kali. Media tanam yang digunakan adalah campuran pasir sungai steril dengan zeolite dengan perbandingan 1: 1 berdasarkan volume dan tanaman inang yang digunakan adalah Pueraria javanica. Tanaman inang dipelihara di rumah kaca hingga 4 bulan kemudian dikeringkan (tanpa disiram selama 2 minggu) untuk memicu produksi spora. Data hasil penelitian menunjukkan bahwa volume media tanam yang paling sesuai untuk memproduksi spora FMA adalah 400 ml dengan jumlah tanaman inang sebanyak 5 tanaman. Dari perlakuan ini diperoleh jumlah spora terbanyak dibandingkan perlakuan lainnya.

Abstract

The presence of pulp in cocoa seeds is known to inhibit seed germination and seedling growth. The conventional method of removing pulp from cocoa seeds is done mechanically by rubbing the seeds with rubbing ash. Conventional pulp removal has disadvantages, such as being less practical and potentially damaging the seed surface. Therefore, it is necessary to try chemically removing the pulp from cocoa seeds by soaking the seeds in a lime solution (CaCO3). This study aims to determine the effect of the duration of cocoa seed soaking in CaCO3 solution and different planting media compositions on seedling growth. The research was conducted from September to December 2021 at a plastic house in Labuhan Dalam Village, Tanjung Senang District, Bandar Lampung, and the Seed Laboratory, Faculty of Agriculture, University of Lampung, Gedong Meneng, Bandar Lampung. The study used a Completely Randomized Design (CRD) arranged in a factorial manner. The first factor was the duration of cocoa seed soaking in CaCO3 solution, consisting of no soaking, soaking for 30, 60, 120, and 240 minutes. The second factor was the planting media composition, consisting of a mixture of rice husk charcoal + manure, sand + manure, and sand + rice husk charcoal + manure. Each treatment combination was replicated three times, resulting in 45 experimental units. The observation data were analyzed using analysis of variance, and the mean differences were tested using the Least Significant Difference (LSD) test at the 5% level. The results of the study showed that the duration of cocoa seed soaking in CaCO3 solution had no effect on cocoa seedling growth. The planting media composition of sand + rice husk charcoal + manure had a significant effect on the best cocoa seedling growth compared to the planting media compositions of rice husk charcoal + manure and sand + manure. Soaking cocoa seeds in CaCO3 solution had no effect on cocoa seedling growth in different planting media. Keywords : Cocoa seeds, pulp, CaCO3, soaking, planting media

Abstract

The aim of this research was to know effectiveness and characteristic of mixing herbicide active ingredients atrazine, mesotrion, and nikosulfuron on several weed specieses. The trial conducted in the green house at South Lampung from December 2021 until February 2022. This Research arranged in a Randomized Completely Design. Treatment consists of four types of herbicides with six level of dosage active ingredient, namely of single herbicides is atrazin 200 g/l (0, 25, 50, 100, 200, and 400 g ha-1), nikosulfuron 20 g/l (0, 2.5, 5.0, 10, 20, and 40 g ha-1), mesotrion 40 g/l (0, 5, 10, 20, 40 and 80 g ha-1), and herbicides combination of atrazine, nikosulfuron, and mesotrion 200/20/40 OD (0, 32.5, 65, 130, 260, and 520 g ha-1). The target weed were 3 type of broadleaves weeds (Ageratum conyzoides, Euphorbia hirta, and Richardia brasiliensis), 3 type of grasses weeds (Digitaria ciliaris, Eleusine indica, and Rottboellia cochinchinensis), and sedges weed (Cyperus rotundus). Multiplicative Survival Model method used in this research because atrazin, nikosulfuron, and mesotrion have different mode of action. Results showed that an active ingredient mixture of atrazin 200 g/l, nikosulfuron 20 g/l, and mesotrion 40 g/l has LD50 expectation value of 155.96 g ha-1 and LD50 treatment of 74.27 g ha-1 with the co-toxicity value was 2.10 (co-toxicity >1), it means that the characteristic oh the herbiscides mixture  is synergist or not antagonist. Keywords: herbicide mixture, atrazine, mesotrion, nikosulfuron, LD50, Multiplicative Survival Model
