Aplikasi AB Mix dan POC Limbah Pertanian terhadap Sawi Pagoda (Brassica narinosa L.) Hidroponik Sistem Wick
Full text linkHydroponic cultivation of pagoda mustard (Brassica narinosa L.) is a solution to increase production time efficiency and produce cleaner and more nutritious vegetables. However, the high price of AB mix fertilizer is an obstacle for hydroponic farmers, so alternative sources of nutrients are needed, such as Liquid Organic Fertilizer (LOF), which utilizes agricultural waste to make it more economical. This study was conducted from July to September 2024 at the screenhouse of the Experimental Farm of Jenderal Soedirman University, Purwokerto, using a Randomized Block Design (RBD) with two treatment factors: the first treatment was the concentration of AB Mix fertilizer (A), which consisted of four levels, namely A0 (0% AB Mix), A1 (25% AB Mix), A2 (AB Mix 50%), and A3 (AB Mix 100%). The second treatment was the concentration of POC (Liquid Organic Fertilizer) from agricultural waste (P) with three levels: P1 (POC 10 mL/L), P2 (POC 20 mL/L), and P3 (POC 30 mL/L). The data were analyzed using analysis of variance, followed by Duncan's Multiple Range Test (DMRT) at a 95% confidence level. The results showed that the 100% AB mix fertilizer concentration produced the highest results in terms of the number of leaves (up to 57), fresh plant weight (up to 92.22 g), dry plant weight (up to 7.35 g), and chlorophyll content (up to 20.73 mg/L). Substitution of agricultural waste POC increased the number of leaves by 2 leaves and fresh plant weight by 54.15 g at a concentration of 16.7 mL/L. The combination of 50% AB mix with 30 ml/L POC provided the best results in increasing nitrogen uptake, plant height, and leaf area
Respon Pertumbuhan dan Hasil Empat Kultivar Jagung Hibrida (Zea mays L.) dengan perlakuan pemupukan Nitrogen dalam sistem Agroforestri Kayu Putih (Melaleuca cajuputi Powell)
Full text linkMaize (Zea mays L.) is one of the primary food crops and is widely utilized across various sectors. Cultivating maize under cajuput (Melaleuca cajuputi) stands often faces nutrient deficiency problems, primarily due to clay-textured soils with alkaline pH, which can limit the availability of both macro- and micronutrients, especially nitrogen. Nitrogen deficiency in maize significantly reduces its productivity. This study aimed to examine the growth and yield responses of four hybrid maize cultivars to nitrogen fertilization and to determine the optimum nitrogen dosage within an agroforestry system. The research was conducted from October 2024 to February 2025 in Srikoyo Hamlet, Bleberan Village, Playen Subdistrict, Gunung Kidul District, Yogyakarta Special Region Province, Indonesia. The experiment was arranged using a factorial randomized complete block design (RCBD) with three replications. The first factor consisted of four hybrid maize varieties: ADV Jago, NK 212, Pioneer 89, and R7 Gold. The second factor was urea fertilizer dosage: 0, 150, 300, and 450 kg/ha. Results showed that the productivity response of ADV Jago followed a quadratic pattern, while NK 212, R7 Gold, and Pioneer 89 exhibited a linear response. The optimum nitrogen dose for ADV Jago was 356.67 kg/ha, yielding a maximum productivity of 6.03 tons/ha, which represents an 83.28% increase compared to the unfertilized control. Meanwhile, application of 450 kg/ha nitrogen to NK 212, R7 Gold, and Pioneer 89 resulted in respective productivities of 6.65; 6.22; and 6.83 tons/ha, reflecting increases of 45.51%; 159.2%; and 123.93% compared to no nitrogen application, respectively
Potensi Ekstrak Daun Jati (Tectona grandis L. f.) sebagai Bioherbisida Gulma Teki (Cyperus rotundus L.) dan Gulma Siam (Chromolaena odorata L.)
Full text linkThe presence of Siam weed (Chromolaena odorata L.) and purple nutsedge (Cyperus rotundus L.) in crop fields has been shown to reduce crop quality and productivity. This issue can be mitigated through the use of bioherbicides derived from teak (Tectona grandis Linn. f.) leaf extract, which contains allelochemicals with herbicidal potential. Therefore, this study aimed to quantify the allelopathic compounds in teak leaves and determine the optimal concentrations for controlling the two weed species during germination and early growth. The research was conducted in January-August 2024 at the Crop Production Management Laboratory, Horticulture Sub-Laboratory, Plant Science Sub-Laboratory, and Plant Ecology Sub-Laboratory, Greenhouse of the Faculty of Agriculture, and Integrated Laboratory for Research and Testing of Universitas Gadjah Mada. Four treatment levels were tested: D0 (control or without apllication), D1 (10% concentration), D2 (20% concentration), and D3 (40% concentration). Teak leaves extract application was carried out on two different weeds, namely Cyperus rotundus L. and Chromolaena odorata L., resulting in a total of 24 experimental units within the study. Teak leaf extract was applied to Cyperus rotundus L. and Chromolaena odorata, producing 24 experimental units. Fresh teak leaves were found to contain 5.47% (w/w) gallic acid equivalent phenols. Concentrations of 10% and 20% were optimal for inhibiting the germination and early growth of Siam weed, whereas 40% was most effective for inhibiting the germination and early growth of purple nutsedge
Pengaruh Dosis Pupuk NPK dan Zat Pengatur Tumbuh terhadap Kesuburan Tanah, Kadar Fenolik dan Perkembangan Bunga Krisan Pada Dataran Rendah
Full text linkChrysanthemums (Chrysanthemum spp.) are a floricultural commodity with high economic value and widespread demand as both cut flowers and ornamental plants. However, chrysanthemums generally grow optimally in highlands with cool temperatures, so their cultivation in lowlands faces various physiological constraints, such as decreased flower quality, delayed flowering, and impaired nutrient absorption. This study aimed to evaluate the effects of different NPK fertilizer dosages and types of Plant Growth Regulators (PGRs) on soil nutrient availability (N, P, K), phenolic content, and flowering development of chrysanthemums cultivated in lowlands. The research was conducted in July–October 2024 at the greenhouse of the Jember State Polytechnic Plant Laboratory (±89 m above sea level) using a factorial Completely Randomized Design (CRD) with two factors: NPK 16-16-16 fertilizer dosage (N1 = 4 g/L, N2 = 5 g/L, N3 = 6 g/L) and PGR types (P1 = paclobutrazol, P2 = gaviota, P3 = BAP). The observed variables included soil NPK content, leaf phenolics, flower number, flower diameter, and chlorophyll. The results showed that PGR had a more dominant effect than fertilizer dosage. The N3P3 treatment produced the highest phenolic content (0.257%), while the N1P1 combination increased soil nitrogen accumulation (0.566%), and the N2P3 combination provided the highest phosphorus (0.338%) and potassium (0.190%). The NPK fertilizer dosage did not significantly affect all parameters, while PGR significantly affected the flowering time and flower number. No interaction was found between the two treatment factors
