The demand for shallots continues to experience a significant increase in consumption. The use of appropriate varieties and improved nutrition is one of the efforts to increase shallot production. The purpose of the study was to determine the effect of fertilizer application methods on the growth and yield of several shallot varieties. The research was conducted in May-August 2023 in Ngringo Village, Jaten District, Karanganyar, Central Java with an altitude of 119.6 masl. This study used a factorial Complete Randomized Group Design (CRD) with two factors. Fertilizer application method was the first factor, namely: sowing and leaking. Varieties became the second factor, namely: Bima Brebes, Bauji, Tajuk, and Batu Ijo, resulting in eight treatment combinations with four replications. Observation parameters included plant height, number of leaves, fresh stalk weight, dry stalk weight, number of bulb, fresh weight of bulb, dry weight of bulb, dry weight of bulb per hectare, and bulb diameter. The results showed that the application of fertilizer by sowing can increase plant height 2-3 weeks after planting, fresh weight of bulbs, and dry weight of bulbs of shallots. The Tajuk variety produces plant height at 5 weeks, the number of leaves at 5 weeks, the fresh and dry weight of bulbs, the number of bulbs, and the fresh and dry weight stalk of shallots higher than other varieties. Fertilizer application by sowing can be applied to the Tajuk variety of shallots. ABSTRAK Kebutuhan bawang merah terus mengalami peningkatan konsumsi yang cukup signifikan.

Varietas menjadi faktor kedua, yaitu: Bima Brebes, Bauji, Tajuk, dan Batu Ijo, sehingga terdapat delapan petak kombinasi perlakuan yang diulang empat kali. Parameter pengamatan meliputi tinggi tanaman, jumlah daun, berat brangkasan segar, berat brangkasan kering, jumlah umbi per rumpun, berat segar umbi per rumpun, berat kering umbi per rumpun, berat kering umbi per hektar, dan diameter umbi. Hasil penelitian menunjukkan aplikasi pupuk dengan cara ditabur dapat meningkatkan tinggi tanaman 2-3 minggu setelah tanam (MST), berat segar umbi per rumpun, dan berat kering umbi per rumpun bawang merah. Varietas Tajuk menghasilkan tinggi tanaman pada 5 MST, jumlah daun pada 5 MST, berat segar dan kering umbi per rumpun, jumlah umbi per rumpun, serta berat brangkasan segar dan kering bawang merah lebih tinggi dibanding varietas lain. Pemberian pupuk dengan cara ditabur dapat diaplikasikan pada bawang merah varietas Tajuk.

Background: Indigofera tinctoria, commonly known as true indigo, is a plant widely used in the textile industry for its natural indigo dye, which produces a rich blue color for fabrics. I. tinctoria, known for its natural bluish-purple dye, generates 10% dye and 90% waste during extraction, requiring effective waste management. This study aimed to optimize organic fertilizer and mycorrhiza doses from I. tinctoria waste for enhancing soil fertility in arid regions. Methods: The study was conducted from May to December 2020 in Puron Village, Bulu District, Sukoharjo Regency. A factorial Completely Randomized Block Design (CRBD) with 2 factors was employed. The first factor consisted of 5 levels of I. tinctoria organic fertilizer treatments: 0, 100, 200, 300, and 400 g per plant. The second factor included 3 levels of mycorrhiza treatments: 0, 10, and 20 g per plant. Variables observed included mycorrhizal infection on roots, plant growth rate, and yield (fresh leaf and shoot weight of I. tinctoria ). Data analysis utilized ANOVA at a 5% significance level followed by Duncan Multiple Range Test (DMRT). Results: The results indicated that organic fertilizer from natural dye waste at a dosage of 200 g per plant increased the percentage of mycorrhizal-infected roots and boosted shoot weight by 63.27% at 8 weeks after planting (WAP). Mycorrhiza at 10 g per plant increased mycorrhizal infection percentage and enhanced shoot weight by 45.98% at 4 WAP. The combination of I. tinctoria extraction waste organic fertilizer at 200 g per plant and mycorrhizal at 10 g per plant showed interaction, significantly increasing the growth of root nodules of I. tinctoria by 84.04% at 12 WAP. Conclusion: The integration of organic fertilizer derived from indigo dye waste and mycorrhiza presents a promising strategy for enhancing I. tinctoria growth and productivity. Novelty/Originality of this Study: This study is distinctive in its demonstration of the effective use of I. tinctoria extraction waste as an organic fertilizer, aligning with zero-waste principles and contributing to improvements in plant growth and soil fertility. Furthermore, it investigates the synergistic effects of mycorrhizal associations on enhancing nutrient absorption and overall productivity of I. tinctoria , an aspect that has not been thoroughly explored in prior research.

The increasing number of Phalaenopsis sp. enthusiasts needs to be balanced with the availability of good-quality cultivars, one of which can be achieved by improving flower morphological characteristics through colchicine induction. Colchicine-induced plants often exhibit superior traits such as larger, thicker, and more durable flowers. This study aimed to investigate the effect of a 1500 ppm colchicine concentration on the floral morphological characteristics of the Phalaenopsis sp., with a particular focus on flower size, petal thickness, and sepal morphology. This research provides genetic diversity information on Phalaenopsis sp., which can serve as a basis for future breeding programs and as a reference material for orchid growers and researchers. The materials used were flower buds of three Phalaenopsis varieties: Phalaenopsis Fuller’s Sunset, Phalaenopsis Golden Tree, and Phalaenopsis OX X-Ray. Each treatment was replicated three times. Morphological data were analyzed qualitatively through scoring and converted into binary data according to the Guide Book of Orchid Plant Characterization by the Ornamental Plant Research Center (2007). The results showed that 1500 ppm colchicine affects Phalaenopsis Fullers Sunset in the form of rhombus-shaped petals, and on Phalaenopsis Golden Tree in the form of pointed lateral sepal tips, concave transverse and longitudinal cross-sections of petals, and on Phalaenopsis OX X-Ray in the form of split dorsal sepal edges, and open petal arrangement. Overall, colchicine treatment also induced apparent enlargement of flowers in all three Phalaenopsis hybrids. Keywords: chromosome; flower morphology; mutagenesis; ornamental plant; polyploidy
