Abstract

ABSTRACT This study aims to study the effect of paclobutrazol on the growth and production of tomato plants. The research was conducted at the Experimental Garden of the Pandu Agricultural Technology Assessment Center in Talawaan Bantik Village, Wori District, North Minahasa Regency. Starting from September 2017 and ending in January 2018. This study used a randomized block design consisting of 6 levels of paclobutazol concentrations of 0 ppm, 75 ppm, 100 ppm, 125 ppm, 150 ppm, 175 ppm. Variables were observed for plant height, time / time of flowering (days after seeding), number of crop collections, and fruit weight. The use of paclobutrazol in tomato plants has a significant influence on plant height at flowering and number of leaves. The administration of paclobutrazol with a concentration of 125 ppm gave the greatest emphasis which produced the lowest plant height of 47.75 cm.  The use of paclobutrazol in tomato plants can delay the flowering process compared to without using paclobutrazol. The effect of paclobutrazol on flowering is a secondary influence, while the primary effect is suppression of vegetative growth. Keywords: Application of Paclobutrazol in Tomato Plants

Abstract

ABSTRACTPotatoes (Solanum tuberosum, L.) are one of the important food commodities after rice, maizeand wheat whose needs continue to increase both to meet domestic needs and even have the potential to beexported. This study aims to determine the effect of NPK fertilizer, Liquid Organic Fertilizer, andTrichocompost on the growth and production of potato (Solanum tuberosum L.). This study used aliterature study method, utilizing the results of research and scientific publications on the effect of NPKfertilization, Liquid Organic Fertilizer, and Trichocompost on the growth and production of potato plants.The results showed that the application of NPK fertilizer, Liquid Organic Fertilizer, and Trichokomposhad an effect on the growth and production of potato (Solanum tuberosum L.). The dose of NPK fertilizergiven to potato plants was 700 - 1,400 kg and could be combined with manure, with production 14.7 -22.5ton ha-1. The dose of liquid organic fertilizer can be given 5-25 ml / liter of water and can produce potatoproduction 23.13 - 34.56 ton ha-1. Tricho-compost biofertilizer can be given in solid form 25 ton ha-1 or inliquid form 5 ml / l -250 ml / l can be sprayed onto leaves or onto the soil, and can give potato production36.8 - 38.3 ton ha-1. Tricho-compost can help suppress and control the attack of soil-borne pathogens suchas Fusarium fungi, Phytophora fungi, and Phytium fungi which are important pathogens in potatocultivation..Keyword : potato, NPK, liquid organic fertilizer, trichocompost

Abstract

This study aims to determine the effect and concentration of kinetin on potato mericlon shoots and to determine the best effect and concentration of coconut water on potato mericlon shoots. This research was conducted at the Plant Genetics Laboratory, Faculty of Agriculture, Sam Ratulangi University, Manado. This study used a completely randomized design (CRD) which consisted of seven treatments namely A0 (control/no treatment), A1 (Kinetin 0.5 ppm), A2 (Kinetin 1.5 ppm), A3 (Kinetin 1.5 ppm), A4 ( Coconut Water 5%), A5 (Coconut Water 7.5%), A6 (Coconut Water 10%). The variables observed were: shoot height, number of leaves, number of roots, and fresh weight. The results showed that the treatment of kinetin and young coconut water had a significant effect on the parameters of shoot height, namely A6 (6.74 cm), number of leaves, namely A1 (8.2 strands) and A6 (8.2 strands), number of roots, namely A3 (11 .3 units) and a wet weight of A3 (0.4591 gram). In this study, a kinetin concentration of 0.5 ppm was good for increasing the number of leaves, and a concentration of 10% coconut water was good for increasing shoot height. Keywords: Potato, Tissue Culture, PGR, Kinetin, Coconut Water.

Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) yang terdiri dari tujuh perlakuan yaitu A0 (kontrol/tanpa perlakuan), A1 (Kinetin 0,5 ppm), A2 (Kinetin 1 ppm), A3 (Kinetin 1,5 ppm), A4 (Air Kelapa 5%), A5 (Air Kelapa 7,5%), A6 (Air Kelapa 10%). Variabel yang diamati adalah: tinggi tunas, jumlah daun, jumlah akar, dan berat basah. Hasil penelitian menunjukan pemberian perlakuan kinetin dan air kelapa muda berpengaruh nyata terhadap parameter tinggi tunas yaitu A6 (6,74 cm), jumlah daun yaitu A1 (8,2 helai) dan A6 (8,2 helai), jumlah akar yaitu A3 (11,3 unit) dan berat basah yaitu A3 (0.4591 gram). Pada penelitian ini, konsentrasi kinetin 0,5 ppm sudah baik untuk peningkatan jumlah daun, dan konsentrasi air kelapa 10% sudah baik untuk meningkatkan tinggi tunas.

Abstract

This study aims to obtain accurate results from the concentration of old coconut water and BAP on Vacin and Went and Murashige and Skoog media on the growth of Dendrobium sp. through in vitro culture. The method used in this study was a completely randomized design consisting of 8 treatments and 8 replications. Each replication consisted of 2 bottles so that a total of 128 bottles, namely A0 (control, without using old coconut water), A1 (12.5% old coconut water), B0 (control, without using BAP), B1 (BAP 0.5 mg/L ), and used 2 types of media (Murashige and Skoog) and (Vacin and Went). The variables observed included the number of protocorm, wet weight, dry weight, and pH of the media. The results showed that the concentration of old coconut water and BAP had a significant effect on the number of protocorm, fresh weight, and pH of the media on Dendrobium sp. The best treatment obtained was VA1B1 (12.5% old coconut water, 0.5 ppm BAP) with a media pH of 5.0 V A1B1, the number of protocorm V A1B1 49.57, and VA1B1 0.008 g which had the best results compared to other treatments.

Abstract

The purpose of the research was to study the effect of biourine on soybean plant growth, and to obtain the concentration of biourine that can increase soybean growth. To achieve the objectives, the research was designed using a completely randomized design. The treatments consisted of, A = No Biourine, B = 100 ml biourine/1 liter of water, C = 200 ml biourine/1 liter of water. Each treatment was repeated four times resulting in 12 experimental pots. The parameters observed were the number of leaves and the number of soybean branches. Data were analyzed using analysis of variance and 5% BNT test. The results showed that the application of biourine increased the growth of soybean plants as indicated by plant height and the number of leaves with three branches. The concentration of 100 ml biourine/1 liter of water increased the growth of soybean plants.

Abstract

Spinach (Amaranthus sp) is a plant belonging to the Amaranthaceae family. Spinach is one of the oldest food plants in the world originating from America, which has been cultivated around 6700 years BC and is now spread throughout tropical and subtropical areas throughout the world. Copra fumigation ash contains macro and micro nutrients that plants need, one of which is potassium. This research aims to determine the effect of copra fumigation ash on the growth of spinach plants. This research was carried out at the Green House, Faculty of Agriculture, Sam Ratulangi University, Manado, North Sulawesi from June to July 2024. This research used a Randomized Group Design (RAK) with six treatments and four replications consisting of Without Ash Copra Fumigation (K0), 5 tons Copra Fumigation Ash/ha (K1), 10 tonnes of Copra Fumigation Ash/ha (K2), 15 tonnes of Copra Fumigation Ash/ha (K3), 20 tonnes of Copra Fumigation Ash/ha (K4) and 25 tonnes of Copra Fumigation Ash/ha ( K5). The research data were analyzed using the F test using the Microsoft Office Excel program to determine the effect of copra fumigation ash treatment on the growth of spinach plants. The research results showed that copra fumigation ash had a significant effect on the variable height of spinach plants but not on the number of leaves and width of spinach leaves. Copra fumigation ash also has a very significant effect on the fresh weight of spinach plants. It is recommended to use copra ash at a dose of 20 tons/ha as the recommended dose for spinach cultivation activities.
