Abstract

The research aimed to propagate tea plants by air layering in order to obtain new plants with shorter immature plants period (TBM), which is 1.5 years, by utilizing wasted branches from routine clean pruning activities in tea plantations. The research was conducted from August 2018 to January 2019 at tea plantation of PT. Pagilaran, Batang, Central Java. Experiment using single factor treatment was arranged in a Completely Randomized Design with three replications. The treatment was layering media, consisting of husk charcoal, moss, and cocopeat, which were applied on GMB 7 and GMB 9 clones. The results showed significant effects of the layering media on the levels of auxin and cytokinin in GMB 7. The highest levels were found in the husk charcoal and moss media. Analysis of sucrose, glucose and total sugar as well as the physiological analysis of the air layering roots showed no significant difference in the fresh weight, dry weight, volume, surface area, diameter, and length of the roots. Husk charcoal resulted in the highest success rate of the air layering in GMB 7, which was 100%. Meanwhile, GMB 9 showed significant difference only in the auxin levels. There was no significant effect of layering media on the analysis of sucrose, glucose and total sugar as well as on the physiological analysis of the air layering roots. Both husk charcoal and moss media resulted in the highest success rate of the air layering in GMB 9, which was 58.33%.

Abstract

Current breeding efforts in soybean largely focus on identifying genotypes with high seed yield and large seed size. Our study applied a mutation using 250 Gy Gamma-Ray Irradiation to soybean cv. Anjasari. The variability in the M1 generation was identified, and the planting was continued to M2 M3, M4, M5 until M6 generation. The objectives of this research were to evaluate mutant lines exhibiting a good performance in yield and morphological characteristics that can support the yield component in M6 generation. This research was conducted from January 2019 to May 2019 at Ciparanje Experiment Station, Faculty of Agriculture, Universitas Padjadjaran, Jatinangor, West Java. The experiment was arranged in a Randomized Completely Block Design with fifteen mutant soybean genotypes as treatments with two replications within each treatment. The results showed several genotypes produced higher yield and better agro-morphological characteristics. The genotypes MR-33, MR-4A, and MR-2A showed significantly higher number of total pods per plant. Meanwhile, the genotypes MR-35A, MR-37, MR-23, MR-36A, MR-3A, MR-29A MR-34A, MR-4A, MR-17, and MR-5A showed a higher value in weight of 100 seeds. The highest yield was observed in MR-29A and MR-23, which then will be used as the genotypes for multilocation test for stability.

Abstract

Nepenthes, also known as pitcher plant, are unique and interesting flora developed as ornamental plants. This species has an attraction not only on the flowers but also on the diverse shapes and colors of the pitchers. Each Nepenthes species and hybrid has a variety of characters. The genetic relationship and diversity in Nepenthes species and hybrids can be determined based on the morphological characterization. The purpose of this study was to determine the similarity level among the Nepenthes accessions based on 31 qualitative characters. In this study, 30 Nepenthes species and 11 hybrids were used. The range of the similarity coefficient of Nepenthes species was 0.28-0.65, and divided into two major groups namely group A and B. Group A was the Nepenthes population which had petioles consisted of 17 accessions, while group B had folius consisting of 24 accessions. It indicated that when the similarity value is higher, the similarity level between each plant becomes higher. Principle Coordinates Analysis (PCoA) provided an overview of the relationship among the genotypes in coordinates. Species with a high similarity coefficient were in a close position, whereas species with a low similarity coefficient were in a remote position. Based on the PCoA, the species were grouped based on the similar characters, which was supported by the dendrograms.

Abstract

A swampland has considerable potential in agriculture. This land has high soil acidity level, and high iron content. Therefore, the application of ameliorant to acid sulfate soil is essential to improve the soil and make it more suitable for rice cultivation. This study aimed to know the effects of phosphorus (P) from Moroccan Rock Phosphate (MRP) and fertilization on swamp rice (Oryza sativa L.). The experiment was conducted at the experimental location of Indonesian Swampland Agricultural Research Institute (ISARI), Puntik Village, Barito Kuala District, South Kalimantan and arranged in a randomized nested design consisting of 100 kg.ha-1 TSP (Control), 750 kg.ha-1, 1,000 kg.ha-1, and 1,250 kg.ha-1 Moroccan rock phosphate with four replications in each treatment.  The yield component of grain increased significantly at 3.77 ton.ha-1. The highest of grain yield was obtained in the application of 1,000 kg.ha-1 MRP. Meanwhile, significant positive correlation was observed between plant height and the number of spikelets per panicle. The application of phosphate fertilizer can increase soil pH, which affects the growth and yield of rice plants such as plant height and yield.
