Abstract

The demand for white mustard in the market will continue to increase every year in line with economic growth, population growth, and growth in people's income, both for food, medicine, or other purposes. One of the efforts made to maintain and improve soil fertility is by providing organic materials such as manure to the soil. The purpose of this study was to determine the response to the use of kasgotchar fertilizer and pearl NPK fertilizer on the production of white mustard (Brassica pekinensis L) varieties of Tahono CR. This study used a Factorial Randomized Block Design with 2 factors: Factor l, namely the provision of Biochar kasgot fertilizer (K) with 3 levels, namely: K0 = Control (0 kg / plot), K1 = 10 tons / ha (1 kg / plot), K2 = 20 tons / ha (2 kg / plot). Factor 2, namely the provision of NPK fertilizer 16: 16: 16 (P) with 4 levels, namely: N0 = Control (0 kg / plot), N1 = 100 kg / ha (0.01 kg / plot), N2 = 200 kg / ha (0.02 kg / plot), N3 = 300 kg / ha (0.03 kg / plot). The parameters observed in this study include fresh weight per crop and production per hectare (kg). The results of the study showed that the use of kasgotchar and NPK fertilizers did not differ significantly on fresh weight per crop, production per hectare. The best treatment was the K2N3 treatment (kasgotchar with a dose of 2 tons / ha, and NPK with a dose of 300 kg / ha. Kasgotchar fertilizer can improve soil chemical properties.

Abstract

This research was conducted at the Biology Laboratory, Faculty of Agriculture, Universitas Katolik Santo Thomas, Medan. This study aims to determine the potential of fragrant pandan leaf extract as a vegetable pesticide in controlling armyworm pests. This study used a non-factorial completely randomized design (CRD). The treatment factor was fragrant pandan leaf extract (Pw) which consisted of 5 treatments and 4 replications, namely: Pw0 = (control/without giving fragrant pandan leaf extract), Pw1 = 20 ml of fragrant pandan leaf extract, Pw2 = 40 ml of pandan leaf extract fragrant, Pw3 = 60 ml of fragrant pandan leaf extract and Pw4 = 80 ml of fragrant pandan leaf extract, each treatment added with 100 ml of distilled water. The results showed that the highest percentage of mortality (100%) at 108 hours after application (JSA) was found in the treatment of 80 ml of fragrant pandan leaf extract + 100 ml of aquadest. The fastest death time of 50% of armyworms was found in the treatment of 80 ml of fragrant pandan leaf extract + 100 ml of aquadest, which was 30 JSA.

Abstract

This study aims to determine the effect of the concentration of gibberellins acid growth regulator (GA3) on the germination of sugar palm seeds. The experiment was carried out at Graha Tanjung Anom with an altitude of about 50 masl from December 2021 to May 2022. The experiment was carried out using a non-factorial Randomized Block Design. The factors studied were the treatment of gibberellins acid concentrations with 8 levels namely G0 ; zero or no gibberellins acid, G1 : 0.5 mg / l ; G2 : 1.0 mg/l ; G3 :1.5 mg/l : G4 :2.0 mg/l : G5 : 2.5 mg/l ; G5 ; 2.5 mg/l ; G6 ; 3.0 mg/l and G7 ; 3.5mg/l. The treatment consisted of 3 repetitions (blocks) so that there were 3x8 = 24 experimental units (plots). Each experimental unit (plot) consisted of 20 seeds (polybags). Parameters observed were the percentage of seeds germinating, average germination age, seedling height, number of leaves and stem diameter. Based on data analysis (Anova), and the discussion some conclusions can be drawn as follows; Concentrations of 0 to 3.5 mg/l GA3 markedly increased the percentage of seed germination, accelerated the germination age of 5.48 days, tended to increase seedling height and number of leaves as well as the diameter of the base of the seedling stems. It is necessary to investigate the effect of GA3 concentration and soaking time on sugar palm seed germination.

Abstract

This study entitled Effect of Mycorrhizal Dosage and Watering Frequency on the Growth of Cocoa (Theobroma cacao L.) Seeds. The purpose of this study was to determine the frequency of watering and the right dose of mycorrhizal fungi in cocoa (Theobroma cacao L.) nursery techniques. In this study using a randomized block design (RBD) consisting of two factors. The first factor is the frequency of watering (P) which consists of 4 levels: P1 = watering once a day, P2 = watering every 3 days, P3 = watering every 5 days and P4 = watering once every 7 days. The second factor was the mycorrhizal dose (M) which consisted of 4 factors: M0 = without mycorrhizal administration, M1 = 25 g mycorrhizal, M2 = 50 g mycorrhizal and M3 = 75 g mycorrhizal. Parameters observed consisted of plant height, stem diameter, number of leaves, leaf area, fresh weight of roots, dry weight of roots, fresh weight of plants and dry weight of plants. The results showed that the treatment of watering frequency significantly increased root wet weight and plant wet weight, but had no significant effect on plant height, stem diameter, number of leaves, leaf area, root dry weight and plant dry weight. Mycorrhizal dose treatment had no significant effect on plant height, stem diameter, number of leaves, leaf area, root wet weight, root dry weight, plant wet weight and plant dry weight. The interaction of watering frequency and mycorrhizal doses had no significant effect on plant height, stem diameter, number of leaves, leaf area, root wet weight, root dry weight, plant wet weight and plant dry weight.

Abstract

This research was conducted to determine the dose of shallot skin extract that is effective for controlling Spodoptera litura F. This research was carried out for 2 months at the Biology Laboratory, Faculty of Agriculture, Santo Thomas Catholic University, Medan. The research design used was a Non-Factoral Completely Randomized Design (CRD) consisting of five treatments and each treatment was repeated four times to form 20 experimental units of Red Onion Skin Soaking (K), namely: K0 = 0% (Control), K1 = 20 gr/liter of water, K2 = 40 gr/liter of water, K3 = 60 gr/liter of water, and K4 = 80 gr/liter of water. The parameters observed were pest mortality, 50% death time and larval behavior after application. From the research results, it can be seen that administering shallot skin extract at the highest dose, namely 80 g/L, can be quadratically used as a botanical insecticide to control S. litura pests with a death time of 27 hours

Abstract

This research aims to determine the effect of shallot extract concentration and soaking time on the growth of pepper plant stems. This research was carried out at the Unika Santo Thomas Medan agricultural experimental field Jl. Setia Budi no. 479, Tanjung Sari, Medan. With a height of around 32 meters above sea level (meters above sea level). This research was conducted from March to May 2023. This research used a factorial Randomized Block Design (RAK) consisting of 2 factors. The first factor is the concentration of shallot extract (K) and the second factor is the soaking time (P). The first factor is the concentration of shallot extract (K) consisting of 4 treatment levels, namely: K0: 0% (control), K1: 30% (30 mL of shallot extract + 70 mL of distilled water), K2: 60% (60 mL of shallot extract + 40 mL distilled water), K3: 90% (90 mL shallot extract + 10 mL distilled water). The second factor is the length of soaking of pepper plant cuttings (P) consisting of 3 treatment levels, namely: P1: 3 hours, P2: 6 hours, P3: 9 hours. Based on the research results, it can be seen that the concentration of onion extract has no effect on the percentage of live cuttings of pepper plant cuttings, but it has a real influence on the length of the shoots with the highest shoots obtained at a concentration of 93.33% at a concentration of 83.77% for the number of leaves. the most. Regarding the number of roots, a concentration of 78.66% produced the highest number of roots.
