Abstract

Coffee is one of the plantation commodities that has significant economic value. A factor that needs to be considered in coffee plant cultivation is good planting media composition. This study aims to determine the effect of planting media composition on the growth of robusta coffee seedlings. This study used a Completely Randomized Design with treatments M0= Soil: 100%, M1= Soil: 50% + Coffee Husk Compost: 25% + Rice Husk: 25%, M2= Soil: 25% + Coffee Husk Compost: 50% + Rice Husk: 25%, M3= Soil: 25% + Coffee Husk Compost: 25% + Rice Husk: 50%. The analyses conducted were compost analysis and initial and post-incubation soil analysis. Observation data were analyzed using the F test followed by DNMRT at the 5% level. The research results show that the provision of coffee husk compost and rice husks affects the chemical properties of the soil and the growth of coffee seedlings. The planting media composition of Soil: 25% + Coffee Husk Compost: 50% + Rice Husk: 25% proved to increase the pH of the planting media from 5.5 to 6.6, increase in total N-value from 0.2% to 0.5%, available P from 18.6 ppm to 38.5 ppm and the soil CEC from 7.6 me/100g to 36.6 me/100g. This planting media composition also makes it possible to enhance the growth of robusta coffee seedlings in plant height, stem diameter, number of leaves, leaf width, and root volume. Thus, this planting media composition is a suitable medium for the growth of robusta coffee seedlings.

Abstract

[APPLICATION OF TITHONIA COMPOST DOSAGE AND PGPR FLORAONE® CONCENTRATION ON THE GROWTH PERFORMANCE AND YIELD OF EGGPLANT].  Eggplant is an important horticultural crop with high nutritional value, essential for maintaining health. Increasing eggplant production can be achieved through the use of superior varieties and optimized cultivation techniques. However, much of Indonesia's agricultural land consists of marginal soils, such as Ultisol, which pose challenges to cultivation. These challenges can be mitigated by incorporating organic materials, such as Tithonia compost, and utilizing Plant Growth-Promoting Rhizobacteria (PGPR).This study aimed to evaluate the interaction effects of different doses of Tithonia compost and concentrations of PGPR FloraOne® on the growth and yield of eggplant. The experiment was conducted from February to May 2023, using a completely randomized design (CRD) with two factors and three replications. Data were analyzed using analysis of variance (ANOVA) with an F-test at a 5% significance level, followed by HSD for mean separation. The results indicated that the combination of Tithonia compost at a dose of 15 tons/ha and PGPR concentration of 45 mL/L yielded the earliest flowering time. Tithonia compost significantly influenced plant height, leaf number, flowering time, number of flowers, fruit length, fruit diameter, fruit number, and fruit weight per plant. Meanwhile, PGPR application significantly affected leaf number, flowering time, and fruit length. These findings highlight the potential of integrating Tithonia compost and PGPR to enhance eggplant growth and productivity, particularly on marginal soils.

Abstract

Celery offers a distinctive flavor to culinary dishes and has biopharmaceutical potential in addressing various health issues. Efforts to obtain high-quality celery in terms of appearance and content continue to be made to meet human needs. The objective of the study is to determine the morphological and physiological responses of celery plants to shade treatment and mung bean sprout extract. The experimental design used a completely randomized design with 2 factors, namely the provision of shade (without shade, 65% shade, 75% shade, and 85% shade) and the provision of bean sprout extract (without bean sprout extract, 10% bean sprout extract, and 30% bean sprout extract). Each treatment was repeated 3 times. Data were analyzed by analysis of variance and Duncan's New Multiple Range Test (5%). Results indicated that 85% shading combined with 30% mung bean sprout extract yielded the highest stomatal density. The same extract concentration also produced the highest chlorophyll a and total content. In contrast, 65% shading resulted in the largest leaf area of celery plants.

Abstract

Seedless watermelons, both seeds and fruits, possess a significantly higher economic value than their seeded counterparts. Serif Saga Agrihorti, a variety developed by the Tropical Fruit Research Institute, offers several advantages, including a sweet taste, high fruit yield, bright red flesh, and large fruit size. However, it is characterized by a relatively high number of seeds. The development of a new seedless variety from Serif Saga Agrihorti is crucial. Polyploid induction using mutagenic agents like colchicine is an effective method to obtain tetraploid female parents. This study aimed to identify the optimal method and colchicine concentration for inducing polyploidy in watermelons and to produce putative tetraploid plants. Polyploid induction was conducted using two methods: directly applying colchicine solution to plant shoots and soaking seeds in colchicine solution for 24 and 48 hours at concentrations of 0.2% and 0.4%. The observed traits included stem diameter, leaf length and width, stomatal length and width, pollen diameter, pollen viability, male and female flowering periods, harvesting time, fruit weight, fruit diameter, seed count, and seed dimensions (length and width). Data were analyzed using an unpaired t-test using the Statistical Tools for Agricultural Research (STAR) software. The results identified four putative tetraploid genotypes based on morphological observations of pollen diameter, stomatal size, and seed dimensions. In conclusion, seed soaking in colchicine solution effectively induces polyploidy in watermelons compared to shoot application.

Abstract

Tanaman gambir (Uncaria gambir (Hunter) Roxb) merupakan komoditi unggulan Sumatera Barat penghasil senyawa polifenol terutama katekin yang memiliki manfaat sebagai antioksidan sehingga digunakan dalam berbagai bahan baku industri seperti farmasi, kosmetik, dan pangan. Prospek pasar ekspor yang tinggi namun mutu gambir yang diekspor masih rendah. Penggunaan kultur suspensi sel dengan penambahan elisitor seperti ion tembaga Cu²⁺ dapat menjadi solusi efektif dengan meningkatkan produksi metabolit sekunder dalam jumlah banyak dan waktu singkat. Penelitian ini bertujuan untuk mendapatkan konsentrasi elisitor Cu2+ terbaik dalam peningkatan kandungan katekin kalus gambir. Penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan pemberian elisitor Cu2+ (0, 2, 4, dan 6 mg/l) sebagai perlakuan. Hasil penelitian menunjukkan bahwa pemberian elisitor Cu2+ belum mampu untuk meningkatkan kandungan senyawa katekin pada kalus gambir karena hanya ditemukan pada perlakuan 0 ppm 7 HSS dan terdapat beberapa senyawa bioaktif yang muncul pada kromatogram pengujian HPLC yang tidak dapat teridentifikasi oleh standar katekin yang digunakan.

Abstract

Potato (Solanum tuberosum L.) is an important crop for food diversification, yet the productivity of the local Cingkariang variety from West Sumatra remains limited due to poor seed quality and viral infection. Tissue culture provides a reliable approach to produce pathogen-free planting material. This study evaluated the interaction of NAA and BAP concentrations on the in vitro growth of Cingkariang potato plantlets. Results revealed significant interactions between the two growth regulators on most growth parameters. The application of 0.3 ppm NAA enhanced node number, shoot formation, and plantlet height without suppressing root growth, while 2 ppm BAP was most effective for stimulating shoot development. These findings highlight the importance of optimizing plant growth regulator combinations to improve micropropagation efficiency of Cingkariang potato.
