Abstract

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.

Abstract

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.

Abstract

Monitoring of Attacks and Control of Fire Caterpillar Pests (Setothosea asigna) on Oil Palm Plants at the Tanah Gambus Plantation of PT. "Socfin Indonesia" aims to describe the results of monitoring and control methods for fireworms in oil palm plantations. This research was conducted in the Three Divisions of Tanah Gambus Plantation, Batu Bara Regency, North Sumatra, from January to April 2024. The study used descriptive methods through field observations, sampling at census points, and re-censuses. Monitoring was conducted to monitor fireworm populations, while primary control was carried out through fogging with Santador 25 EC insecticide and diesel. This paper presents an integrated approach to controlling fireworms, which damage oil palm productivity. This study highlights the important role of routine monitoring, which involves mapping infestation points in specific blocks and establishing infestation criteria (light, moderate, and heavy) to determine appropriate control methods. In addition to chemical techniques, control also considered alternative control methods such as biological control with natural predators. The results showed variations in fireworm populations across blocks, influenced by environmental conditions such as high humidity. Post-control re-censtrals were conducted to measure the effectiveness of these methods
