Abstract

Patchouli (Pogostemon cablin Benth.) is a plantation crop which produces essential oil. Sidikalang patchouli variety has not yet been able to reach the maximum yield, it just 13,66 ton/ha. The causes is difficulty of cultivating patchouli generatively. Field experiment were carried out to evaluate the length of soaking time and concentration level of shallot extract (Allium cepa L.) on patchouli cuttings growth in the filed of Bumi Rejo Farmer Group, Cendana, Purbalingga from September to October 2019. The experiment was set up as a 4x4 factorial design in a Completely Randomized Design (CRD) with 10 replications. The first factor was long cuttings immersion (minutes) P1: 60, P2: 90, P3: 120, and P4: 150. The second factor is concentration level (%) T0 : control, T1 : 25, T2 : 50, dan T3 : 75. The data obtained were evaluated using analysis of variance (ANOVA) to determine the effect of treatments applied continued with Duncan’s Multiple Range Test (DMRT) at 5% signficance level to determine the differences between treatment. The length of shallot extract soaking time treatment had no effect on all parameters. The concentration level treatment had a significant effect on the parameters of shoot length and total number of shoots. The interaction had a significant effect on the total number of leaves

Abstract

Basil (Ocimum basilicum L.) is an aromatic plant that is known for its spice and medicinal benefits that valued mainly for its fresh and dry leaves (simplicia/crude drugs). This study aimed to evaluate growth, simplicia production, and total phenolic content of basil under different levels of drought stress and harvest time. The experiment was conducted at The Greenhouse of Plant Breeding and Physiology Laboratory Faculty of Animal Science and Agriculture Diponegoro University. The research was using a completely randomized design (RAL) consisting of two factors 3x3 with 3 replication. Drought stress treatments in field capacity included : K1 (100% FC), K2 (75% FC), and K3 (50% FC) as the first factor. Harvest time treatments included : W1 (5 Weeks After Planting), W2 (6 Weeks After Planting), and W3 (7 Weeks After Planting) as the second factor. Parameters evaluated were root volume, plant height, total leaf area, simplicia production, and total phenolic content. Analysis of Variance (ANOVA) and Tukey test (p≤0,05%) were carried out to determine significant different between treatments and interactions. Results indicated that: (a) drought stress treatments significantly reduced growth and production of basil plant simplicia, but it did not provide a significant difference in the total phenolic content; (b) the harvest time treatment increased growth and production of basil plant simplicia, and decreased total phenolic content significantly; and (c) there were interactions between drought stress treatments and harvest time treatments.

Abstract

Kebutuhan buah tomat di Indonesia selalu meningkat sehingga perlu adanya tindakan peningkatan produksi dengan pemanfaatan mikroorganisme tanah dan pemupukan. Cendawan mikoriza arbuskular merupakan salah satu mikroorganisme tanah yang mampu meningkatkan penyerapan unsur hara dalam tanah sehingga memenuhi kebutuhan tanaman. Penelitian ini bertujuan untuk mengevaluasi dosis aplikasi inokulum cendawan mikoriza arbuskular (CMA) dan pemupukan yang terbaik untuk pertumbuhan dan produksi tanaman tomat. Penelitian dilaksanakan pada bulan Maret 2022 sampai dengan bulan Juni 2022 di Green House, Laboratorium Fisiologi dan Pemuliaan Tanaman, Laboratorium Ekologi dan Produksi Tanaman, Fakultas Peternakan dan Pertanian, Universitas Diponegoro, Semarang. Penelitian menggunakan Rancangan Acak lengkap (RAL) Faktorial 3 x 5 dengan 3 kali ulangan. Faktor pertama adalah perbedaan dosis CMA, yaitu J0: 0 g/tanaman, J1: 10 g/tanaman, J2: 20 g/tanaman. Faktor kedua adalah perbedaan dosis pemupukan yaitu, P1 = 60 kg/ha N, P2O5, dan K2O (400 kg/ha), P2 = 90 kg/ha N, P2O5, dan K2O (600 kg/ha), P3 = 120 kg/ha N, P2O5, dan K2O (800 kg/ha), P4 = 150 kg/ha N, P2O5, dan K2O (1000 kg/ha), P5 = 180 kg/ha N, P2O5, dan K2O (1200 kg/ha). Data dianalisis menggunakan ANOVA (Analysis of Variance) dan uji lanjut dengan Duncan Multiple Range Test (DMRT) pada taraf lima persen (5%). Hasil penelitian menunjukkan bahwa perlakuan dosis inokulum cendawan mikoriza arbuskular memberikan pengaruh nyata pada parameter persentase kolonisasi cendawan mikoriza dan jumlah daun tanaman tomat.

Abstract

The need for chili in Indonesia is always increasing every year, so it is necessary to take action to increase production by fertilization and using plant regulatory substances. This study aims to examine the effect of giving the best dose of potassium fertilizer and gibberellin concentration for the growth and production of chili plants. The research was conducted from May 2022 to August 2022 at the Screen House, Laboratory of Physiology and Plant Breeding, Laboratory of Ecology and Plant Production, Faculty of Animal Husbandry and Agriculture, Diponegoro University, Semarang. The research design used a 4 x 4 factorial design on the basis of Completely Randomized Design (CRD) with 3 replications. The first factor was the difference dose of K2O, K1: control (without K2O), K2: 60 kg/ha K3: 120 kg/ha dan K4: 180 kg/ha. The second factor was the difference concentration of gibberellin, G1: control (0 ppm), G2: 100 ppm G3: 125 ppm dan G4: 150 ppm. The data was analyzed using ANOVA (Analysis of Variance) and further test with Duncan Multiple Range Test (DMRT) at the level of five percent (5%). The results showed that the treatment of K2O fertilizer had a significant effect on the parameters of the plant height, the number of leaves and potassium up take of chili plant. Keywords: chili,gibberellin, K2O

Abstract

This research aimed to determine the effect of cutting position and the concentration of onion extract as a natural hormone on stevia stem cutting propagation. This study used a Factorial Completely randomized design in which the first factor was Apical Cutting (P1), Middle cutting (P2), and Bassal Cutting (P3), and the second factor was control (R0), shallot extract concentration 25% (R1), shallot extract concentration 50%(R2), shallot extract concentration 75% (R3), shallot extract concentration 100% (R4) and Rootone F 25 ppm (R5). The position of cutting has significantly resulted in Times of bud growth, number of roots, number of leaves, and plant height. The concentration of shallot extract has significant results in times of bud growth, number of roots, length of root, number of leaves, plant height, weight of plant, and weight of dry plant. The best performance was apical cuttings and shallot extract concentration of 100%.
