Abstract

Application of Mono Potassium Phosphate Fertilizer (MKP) and EM4 Concentration on the Growth Development of Chili Peppers (Capsicum annum L.). The purpose of this study was to determine the application of MKP fertilizer and EM4 concentration on the growth development of chili peppers (Capsicum annum L.). This research was carried out at the Research Field of the Faculty of Agriculture on Jalan Sultan Iskandar Muda Airport, Blang Bintang District, Aceh Besar District, Cot Karieng Village, Aceh Besar Province. The research time was ± 3 months, starting from the beginning of November 2021 to the end of January 2023. This study used a Completely Randomized Design (CRD) 4x4 Factorial Pattern with 3 replications. The first factor was the concentration of mono potassium phosphate (MKP) fertilizer with 4 levels, namely: M0 = control, M1 = 250 ml of water, M2 = 500 ml of water, M3 = 750 ml of water. The second factor was the concentration of EM4 consisting of 4 levels, namely: E0 = control, E1 = 5 ml of water, E2 = 10 ml, E3 = 15 ml of water. The results showed that the concentration of mono Potassium Phosphate (M) had a significant effect on fruit length observations, but had no significant effect on plant height observations at 15, 30, 45 and 60 days after planting. And did not significantly affect the observation of plant height 15 and 30 days after planting and fruit length observations. There was an interaction that had a very significant effect due to the concentration of mono potassium phosphate (M) fertilizer and the concentration of EM4 (E) which had a significant effect on the observation of fruit length. And did not significantly affect the observation of plant height aged 15, 30, 45 and 60 days after planting.

Abstract

Sawi Pahit (Brassica juncea L.) merupakan salah satu jenis tanaman hortikultura jenis sayur sayuran berasal dari daerah Tiongkok (Cina) dan Asia Timur. Tanaman sawi di budi dayakan sejak 2500 tahun yang lalu di daerah Cina Pada abad XI tanaman sawi masuk ke Indonesia bersamaan dengan lintas perdagangan jenis sayuran sub-tropis lainnya. Penelitian telah dilaksanakan di Desa Selayang, Kec.Selesai Kabupaten Langkat, Sumatera Utara pada bulan Oktober 2022 sampai dengan Desember 2022. Perlakuan pupuk hayati sebagai campuran media tanam yang terbaik adalah K1 (kompos+Mikoriza) terhadap hasil produksi tanaman sawi pahit. Interaksi media tanam dan pengaplikasian insektisida nabati berpengaruh nyata terhadap hasil produksi Secara umum perlakuan interaksi K1W2 (kompos + mikoriza) dan pengaplikasian insektisida 2 minggu sekali berpengaruh nyata terhadap hasil produksi.

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

The oil palm plant (Elaeis guineensis Jacq.) originates from West Africa, is the mainvegetable oil producing plant which has a higher productivity than other vegetable oil producing plants. This study aims to determine the effect of nitrogen fertilizer application onthe number of leaves and stem diameter of oil palm seedlings. The study used a factorialrandomized block design (RBD) with 2 treatment factors, namely the planting mediafactor and the urea fertilizer application factor. The results of the analysis showed that thetreatment of the growing media had a significant effect on the number of leaves. The ureatreatment showed no significant effect on the number of leaves and the interaction of thetwo factors had no significant effect on the number of leaves.

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.
