The objective of this study is to investigate the impact of oil palm bed ash at different doses on the growth and yield of black soybean plants (Glycine soja L.) in different types of soil. A Factorial Randomized Group Design (RAK) with two factors was used in this study. The first factor is the application of oil palm bed ash, a byproduct of burning palm fruit bunches. The second factor is the type of soil used in the experiment. The study's results indicate that andosol and alluvial soil types produce higher 100 seed weight, dry seed weight per plant, dry seed weight per plot, and number of pods per plot compared to ultisol soil and have a faster flowering age. However, these soil types have no significant effect on plant height, the number of productive branches, and plant root length. The combination of palm kernel ash and soil type had a significant effect on 100 seed weight, dry seed weight per plant, dry seed weight per plot, and number of pods per plot. However, this combination had no significant effect on plant height, flowering age, the number of productive branches, and root length. The largest dry seed weight per plot was observed in the K3M2 treatment combination at 78.25 g, and the smallest dry weight per sample was in the K0M1 treatment combination at 47.93 g. This resulted in a 30.32 g increase in dry seed weight per plot (63.27%). The utilization of palm kernel ash at a dosage of 375 g/polybag leads to a 34.26% increase in the dry seed weight per plant, a 30.20% increase in dry seed weight per plot, and a 42.06% increase in the number of pods per plot compared to plants without palm kernel ash application.

This research aims to describe the production of Granola Variety potato seeds from tissue culture (plantlets) and mini cuttings in the Taruna Bina Tani green house in Bukit Village, Dolat Rakyat District, Karo Regency. The observation technique is carried out by direct observation and running a questionnaire. Mini cuttings plants sourced from plantlets will have the same genetic characteristics as their parents, meaning that even though the shoot stem cuttings are small, the results of propagation using the mini shoot cuttings system are also the same as plants originating from tissue culture seeds (parent seeds). Toruna Bina Tani is one of the producers of virus-free Granola Variety potato seeds in Tanah Karo. This business started in 2018. The breeding screen house covers an area of 5000 meters which actively produces generation 0 (G0) to generation 2 (G2) potato seeds which are distributed to farmers.The results showed that the growth of plantlets and mini cuttings was not different, the production of the number of plantlet tubers was greater than the production of the number of tubers of mini cuttings, on the other hand, the weight of tubers per plant, the weight of tubers per tuber and the weight of tubers per rack were smaller in plantlets than in mini cuttings. . Propagation via mini cuttings taken from plantlets is very effective in accelerating the fulfillment of quality seeds (G0). Each individual plantlet can produce 83.8 mini cuttings.

This research aims to determine the effect of two arrangements and density of planting holes on the growth and yield of the kumala mustard variety (Brassica juncea L) in verticulture cultivation. This research was carried out behind the screen house of the Faculty of Agriculture, Santo Thomas Catholic University, Jln. Setia Budi 479 F, Tanjung Sari Medan, North Sumatra Province with an altitude of ± 32 meters above sea level. Starting from May-June 2024. This research used a non-factorial Complete Randomized Block Design (RAKL) consisting of 6 treatments with 3 replications. The treatment factors are P1 = 4 x 12 holes/stem, L1 = 4 x 12 holes/stem, P2 = 4 x 9 holes/stem, L2 = 4 x 9 holes/stem, P3 = 4 x 7 holes/stem, L3 = 4 x 7 Holes/rod. The tools used in this research were pipes (4 inches), saws, machetes, paranets, tape measures, verses, pencils, drink bottles, drills, pottray cups, and wood. The materials used were mustard seeds (kumala variety), wire, soil (soil cleaned of rubbish), water, chicken and goat manure. The research data were analyzed using variance based on a linear model. The effect of the two arrangement treatments and the density of the number of planting holes had no significant influence on the number of leaves, leaf length and fresh weight of plant roots. However, it has a real influence on the height of the green mustard plant, the wet weight per plant and the wet weight of the plant per unit. The best treatment among the other treatments is the L2 treatment (horizontal arrangement with 9 holes.

This study aims to see the effect of IAA concentration and find the optimum IAA concentration on the growth of stem cuttings of Jupiter variety grapes. The parameters observed in the experiment include: Percentage of budding cuttings, Age of budding cuttings, Number of buds per cuttings 65 hst, Height or Length of shoots 65 hst, Number of leaves per cuttings 65 hst, and Number of live plants 90 hst. Based on the results of experimental data analysis and discussion, several conclusions can be drawn as follows: IAA concentration treatment has a significant effect on increasing the percentage of sprouted cuttings, shoot length 65 hst and number of live plants 90 hst, IAA-optimum concentration for the percentage of sprouted cuttings is 50 ppm IAA, 65 HST shoot length is 35 ppm IAA, and the number of live plants is 33.33 ppm IAA. Growth of grape stem cuttings was higher at concentration treatments lower than 100 ppm IAA concentrations. The effect of IAA concentration on the growth of grape stem cuttings effectively promotes growth lower than 100 ppm concentration, whereas treatment of higher concentrations markedly suppresses the growth of observed parameters. The optimum IAA concentration in more valid grape stem cuttings needs to be experimented with the effect of IAA concentrations below 100 ppm on the growth of Jupiter grape cuttings, because the regression equation obtained in this experiment is influenced by the level of treatment performed.

This study aimed to determine the effect of organic and inorganic fertilizer dosages on the growth and development of red chili plants (Capsicum annuum L.). The experiment was conducted using a factorial Randomized Block Design (RBD) with 9 treatment combinations (3 × 3). The first factor was chicken manure with the following doses: P0 = control, P1 = 2.6 kg, and P2 = 5.2 kg. The second factor was NPK 16:16:16 fertilizer with the following doses: N0 = control, N1 = 100 g, and N2 = 200 g. The experimental procedures included land preparation, mulching, planting, watering, replanting, weeding, and harvesting. The observed parameters were plant height (cm), stem diameter, yield per plot, and descriptions of pests and diseases (OPT) attacking the chili plants. Application of chicken manure did not significantly affect the observed parameters, although it showed an increase in plant height, stem diameter, and yield per plot compared to the control. The application of chicken manure and NPK fertilizer at 2, 4, 6, and 8 weeks after planting (WAP) had no significant effect on chili plant height. However, plants treated with chicken manure and NPK tended to grow taller than those without fertilization. Similarly, the combined application of chicken manure and NPK had no significant effect on stem diameter at 2, 4, 6, and 8 WAP. In contrast, the application of chicken manure and NPK significantly affected fruit weight per plot. The highest fruit weight was obtained in the N2 treatment, which was significantly different from N0 and N1. The interaction between chicken manure and NPK fertilizer had no significant effect on any of the observed parameters.
