Abstract

The research aimed to determine the effects of the potato and banana extract supplements in fresh form and flour with different measurements on the growth of plantlet orchid Dendrobium sp in vitro. Factorial Random Planning (RAL) consists of two factors: type of additive and measurement against 16 combinations of treatments, and five repetitions. In total, there are 320 samples of plants. Observations included the percentage of live plantlets, the start time of the shoots, the shoot height, the number of leaves, the root initiation time, the root number, and the root length. The results of the study showed that there was an interaction between the type of additive and the mark against the percent of living plantlets at age 4, 8, and 12 weeks, the height of shoots at age 8 and 12, the root initiation times, the count of roots and the length of the root. The growth percentage ranges from 80-100%, except for the potato flour additive 200 g/l of 45%. Potato and banana additives in the form of flour can increase the start time of the shoots faster than in the fresh form.

Abstract

Indonesia has the potential of muscovy duck resources with various characteristics and qualities that are spread throughout the region. muscovy duck has a larger body size than ducks but has a weakness in terms of lower egg production. To produce ducks with high body weight and egg production, Indonesian breeders often cross muscovy ducks with ducks. The use of a cross model with 4-crossbreeding is an efficient strategy, but genetic improvements need to be made to the two parents including the muscovy duck and the ducks itself because, in some crosses, sterile hybrid results will be obtained. The use of artificial insemination can be done to support the crossing of offspring in obtaining the desired production results. Therefore, a recording should be made to determine the quality of the offspring either using natural marriage or with the help of artificial insemination and its effectiveness on fertility in the next few periods. The use of marker-assisted selection (MAS) can help in the selection to get superior mutton traits and to find out the metabolic pathways related to the formation of the desired body weight and liver weight.Keywords:  genetic quality, 4-crossbreeding, muscovy duck, marker-assisted selection (MAS)

Abstract

This research aims to provide information about Fusarium oxysporum fungus attacks and their control. Several published research results show the severity of attacks is up to 80% and is economical. Fusarium oxysporum fungal infection occurs on the roots and tubers, due to root infection and tuber rot, discoloration, and necrosis of the base layer of the tuber. Furthermore, the fungal mycelium grows rapidly and an anomaly can be seen starting from the base of the tuber and spreading to the top and sides so that the stem grows longer, the leaves do not grow upright but curve, twist or become molten so that the plant wilts and ultimately the plant dies. Control using technical culture methods for cultivating healthy plants and crop rotation systems, using organic materials as a medium for anti-antagonistic microbes, applying the biological agent's Actinomycete, Streptomyces, Trichoderma gloeosporioides and exploiting the potential of anti-pathogenic microbes in the rhizosphere.

Abstract

This study aimed to investigate the impact of various substrates and nutrients on the growth and yield of Brazilian spinach (Alternanthera sissoo) in a floating raft hydroponic system. The research was used a factorial Completely Randomized Design (CRD) with two factors: substrate type (M) consisting of rice husk charcoal, sphagnum moss, and compost; and nutrient type (A) comprising AB Mix, NPK, and Gandasil D. There were 9 treatment combinations, each replicated 3 times, resulting in a total of 81 plant samples. The observed parameters included time to sprouting, plant height, number of leaves, number of branches, canopy diameter, fresh weight, and dry weight of the plant. The results showed a significant interaction between substrate and nutrient types on the number of branches at 6 weeks after planting, while no interaction was observed for other parameters and the best results were obtained from the combination of rice husk charcoal substrate and AB Mix nutrient. Substrate and nutrient types significantly affected plant growth (height, number of branches, and canopy diameter) and yield (fresh and dry plant weight as well as fresh and dry root weight). Rice husk charcoal and AB Mix nutrient produced the best plant growth and yield up to 6 weeks after planting.

Abstract

The decline in red spinach (Amaranthus tricolor L.) production in Indonesia has prompted the need to explore effective and environmentally friendly alternatives to conventional fertilizers. This study examines the potential of cow biourine as a liquid organic fertilizer to increase the yield and nutritional quality of red spinach. The field experiment used a Randomized Block Design with five levels of biourine concentration (0, 200, 400, 600, 800 ml). The variables measured included growth components (fresh weight and productivity) and quality (protein and calcium content). The analysis results showed that the application of cow biourine significantly increased fresh weight, productivity, and calcium content. A dose of 400 ml proved to be the optimal treatment with a wet weight of 120.16 g, a productivity of 4.71 tons/ha, and a calcium content of 469.83 ppm.

Abstract

The success of budding is influenced by various factors, including the technique employed and the application of Plant Growth Regulators (PGRs). This study aimed to determine the most effective budding technique and type of PGR to enhance the success rate and initial growth of Siam Pontianak citrus (Citrus nobilis var. microcarpa) seedlings. The research was conducted from March to May 2025 in Batu City, East Java, using a Factorial Randomized Complete Block Design (RCBD). The first factor was the budding technique: patch budding, T-budding, and chip budding. The second factor was the type of PGR: control (water), young coconut water (500 ml/L), and Atonik (1 ml/L). The analysis of variance (ANOVA) revealed no significant interaction between the two factors. However, as independent factors, the chip budding technique resulted in the highest success percentage and number of shoots (P0.05). The application of coconut water led to the fastest sprout emergence, as well as the greatest shoot height and number of leaves compared to the other PGR treatments and the control. It is concluded that chip budding is the superior method for graft union success, while coconut water is the most effective PGR for promoting the initial vegetative growth of the budded seedling.
