Abstract

Dendrobium orchids have the potential to be developed because they have a variety of types, shapes and sizes. The choice of planting media and fertilization is an important factor in the success of orchid propagation, especially at the acclimatization stage. The aim of this research were determine the type of planting media and the best interval for giving foliar fertilizer and determine the best interactions and combinations of treatment of the type of planting media and the interval for giving foliar fertilizer on the growth of dendrobium orchid plantlets in the acclimatization and enlargement stages. This research used a factorial Randomized Block Design (RAK) with the first factor being the type of planting media and the second factor being the interval of foliar fertilizer application. The first factor includes M1: wood charcoal, M2: cocopeat, M3: wood charcoal + cocopeat 1:1, M4: wood charcoal + cocopeat 1:2, and M5: wood charcoal + cocopeat 1:3. The second factor includes P1: once every 4 days, P2: once every 8 days, P3: once every 12 days. The results of the research showed that the cocopeat planting media type provided the best percentage of acclimatization success for the Dendrobium Blue twist x Dendrobium Biggibum orchids. Providing foliar fertilizer at 8-day intervals provides the best increase in plantlet height and leaf width at the acclimatization and plantlet enlargement stages of Dendrobium Blue twist x Dendrobium bigibbum orchids. There was no interaction between the use of planting media type and the interval of foliar fertilizer application.

Abstract

Curly red chilies are one of the horticultural products that have the potential to be developed because they have high economic value, however the production of curly red chilies in Lampung Province has continued to decline in the last 4 years. One way to increase production value is to increase soil fertility by increasing fertilization. Fertilization is carried out to replace nutrients lost due to rainwater by using fertilizer containing the elements N, P and K, one of which is KNO3 and KH2PO4 fertilizer. The aim of this research is to find out which combination of KNO3 and KH2PO4 is better and to find out whether the single application of KNO3 and KH2PO4 is good for the growth and yield of curly red chili plants. The research used a factorial randomized block design consisting of 2 factors. The first factor is the concentration of KNO3 fertilizer, with 3 levels, namely 3; 4; 5g/l. The second factor is the concentration of KH2PO4 Fertilizer, with 3 levels of 3,5; 4,5; 5,5g/l. Each treatment was repeated 3 times, so there were 9 treatment combinations and 27 experimental units. The variables observed were plant height, stem diameter, number of shoots, fruit weight per plant, number of fruit per plant and root length. Potassium nitrate (KNO3) fertilizer treatment with a concentration of 5 g/l and potassium dihydrophosphate (KH2PO4) 5,5 g/l had a significant effect on plant growth in plant height. Providing potassium nitrate (KNO3) fertilizer with a concentration of 4 g/l and potassium dihydrophosphate (KH2PO4) 5,5 g/l had a significant effect on plant growth including the number of branches and stem diameter. Providing potassium nitrate (KNO3) fertilizer with a concentration of 4 g/l and potassium dihydrophosphate (KH2PO4) 4,5 g/l had a significant effect on plant yields including the number of fruit/plants and the weight of the fruit/plant.

Abstract

Stem cutting propagation is commonly used to vegetative propagated of Aglaonema sp, however the growing roots has not been much growth. Nevertheless, the shoots that grow only one to three buds with the length of time shoots and roots appear is about 50-75 days after cuttings. It is all depends on the genotype of the Aglaonema sp. The aims of this study was to (i) determine the effect of IBA and NAA concentration in inducing roots of Aglaonema sp. Var Siam Aurora stem cuttings; (ii) to determine the interaction of IBA and NAA treatments to inducing roots of Aglaonema sp. Var Siam Aurora; (iii) determine the best combination of IBA and NAA to inducing roots of Aglaonema sp. Var Siam Aurora. The experimental design was Randomized Block Design (RBD) Factorial with the first factor is the IBA concentration; 0 mg.l-1(I0) and 1000 mg.l-1(I1). The second factor is NAA concentration; 0 mg.l-1(N0), 500 mg.l-1 (N1), 1000 mg.l-1 (N2), 1.500 mg.l-1 (N3)and 2000 mg.l-1 (N4) and resulting 10 combination treatments of IBA and NAA. The data was conducted with analysis of variance and followed by BNT test at 5% and the variable observed were root length, number of roots, first time of roots growth, first time of buds growth, the percentage of cutting stem. The result showed that the combination of IBA and NAA 1000 mg.l-1 give significant effect to inducing cutting stem of Aglaonema sp. Var Siam Aurora.

Abstract

NFT hydroponic is a plant cultivation technology that allows plant roots to grow on a shallow nutrient layer on the narrow field. The goal of this study was to evaluate the best NPK 16-16-16 fertilizer concentration and planting media, as well as the combination of the best NPK 16-16-16 fertilizer concentration and planting media, on the growth and yield of pakchoy (Brassica rapa L). This study used a split plot in factorial randomized block design. The first factor is the concentration of AB mix fertilizer as a control at 1400 ppm (N1) and the concentration of NPK fertilizer, namely: 758 ppm (N2), 1000 ppm (N3). The second factor element is the type of planting medium, which consists of 6 media: rockwool (M1), cotton (M2), sponge (M3), fern (M4), charcoal husk (M5), and cocopeat (M6), with 2 repetitions and 18 treatment combinations. Plant height (cm), number of leaves (pieces), leaf width (cm), leaf length (cm), wet weight of sample plants (grams), and dried weight of plants (grams) were the observation variables. In comparison to an NPK nutrient concentration of 1000 ppm, providing an NPK fertilizer concentration of 758 ppm resulted in better growth and yield in the parameters of number of leaves, wet weight, and dry weight of pak choy plants. Using husk charcoal as a planting medium resulted in superior growth and results in the plant height, number of leaves, leaf width, leaf length, and wet weight of pakchoy plants.

Abstract

Organic chili cultivation has become a necessity nowadays as awareness increases about the dangers of chemical residues used in conventional cultivation practices. Chili is one of three main of vegetables commodities in Lampung. However, pepper yellow leaf curl disease is still a major obstacle faced by farmers to increase chili productivity. Therefore, the aim of this research is to study the characteristics of symptoms and the incidence rate of pepper yellow leaf cull disease of Capsicum annuum L. and Capsicum frutescens in organic cultivation practice. The results shown that the characteristics or early symptoms of pepper yellow leaf curl disease on chilies are yellowing of young leaves, mosaic and malformation which are found in C. annuum L and C. frutescens. The intensity of disease attacks on chili plants by giving POC from the Mimosa pudica roots (PM) gave positive efect with an average low attack intensity in the 8th week, namely 32% compared to giving POC from bamboo roots (AB) with an average attack intensity 45.5%. This indicates that POC from the roots of Mimosa pudica (PM) is capable of being a bioprotectant for chili plants. The application of POC type 3 also provided a positive response with a low intensity of pepper yellow leaf curl disease on C. frutescens.

Abstract

Dendrobium Gradita 31 has superior characteristics that are in demand by the market in Indonesia, so seeds with sameness quality, the same characteristics as the parent and in large quantities are needed. Tissue culture is one solution to support the availability of seeds in large quantities and have a high level of sameness quality. The process of regulating the type of ZPT and concentration in the culture media does not always produce the same regeneration pathway. This research aims to determine the regeneration pathway and to obtain the best type and concentration of cytokinin to support its regeneration pathway. This study used a completely randomized design with 3 replications. The first factor is the type of cytokinin, BA and Tdz. The second factor is the concentration of Benzyladenine and Thidiazuron, 1, 2 and 3 mg/l.. The data was analyzed using analysis of variance, and mean value was tested using tukey test 5%. The results of this study indicate that the regeneration pathway in the formation of adventitious shoots was indirect embryogenesis. The use of Tdz 3 mg/l was able to produce the highest percentage of somatic embryo formation and the highest number of somatic embryos. The fastest shoot formation time, shoot formation percentage and the highest number of shoots per clump were found BA 2 mg/l.
