Permintaan bawang merah yang meningkat membutuhkan terobosan teknologi peningkatan produktivitas, termasuk di tanah vertisol. Penelitian ini bertujuan untuk mengetahui pengaruh  dosis pupuk kandang sapi  terhadap pertumbuhan dan hasil True Shallot Seed di  tanah vertisol.  Penelitian dilaksanakan di Desa Plembutan, Kapanewon Playen, Kabupaten Gunung Kidul pada September-Desember 2021 dengan menggunakan Rancangan Acak Kelompok  Lengkap (RAKL) faktorial 3  ulangan. Faktor Pertama adalah dosis pupuk  kandang sapi (T); T1 = 10 ton/ha;  T2 = 20 ton/ha; dan T3 = 30 ton/ha.  Faktor kedua adalah Varietas (V): V1 = Maserati, V2 = Lokananta, dan V3 =  Sanren. Parameter pengamatan adalah tinggi tanaman dan jumlah daun  3, 5 dan 7 mst, bobot segar dan bobot kering oven 6 mst, serta produktivitas.  Data dianalisis dengan anova dan DMRT 5%. Hasil penelitian menunjukkan dosis pupuk kandang sapi tidak nyata berinteraksi dengan varietas TSS pada semua parameter. Peningkatan dosis pupuk kandang sapi nyata berpengaruh terhadaap jumlah daun 7 mst, bobot segar tanaman 6 mst, tetapi tidak nyata berpengaruh terhadap tinggi tanaman 3-7, jumlah daun 3 dan 5 mst, bobot kering oven  6 mst dan produktivitas. Produktivitas bawang merah yang terbaik diperoleh pada dosis pupuk kandang sapi 30 ton/ha. Varietas TSS nyata mempengaruhi tinggi tanaman 3-7 dan jumlah daun 7 mst, bobot segar dan bobot kering oven  6 mst, tetapi tidak nyata pada jumlah daun 3 dan 5 mst dan produktivitas. Produktivitas tertinggi pada varietas Lokananta, diikuti Sanren dan Maserati.

The study aimed to determine the adaptability of varieties and spacing of shallots in the rice fields of Sleman Regency to yield. The study used a Factorial Completely Randomized Block Design with 5 replications. The first factor is Variety (V), consisting of V1 = Head, V2 = Crok Kuning, and V3 = Srikayang. The second factor is Planting Distance (J) consisting of J1 = 15 x 15 cm2, J2 = 15 x 20 cm2, J3 = 20 x 20 cm2, and J4 = 25 x 20 cm2.  The results showed that the spacing of plants did not significantly interact with all parameters. The use of shallot varieties significantly affected plant height at 3 and 5 WAP, tuber diameter, and stover productivity in wet and dry conditions but had no significant effect on the number of tillers per clump and stover weight per clump in wet and dry conditions. Spacing treatment significantly affected agronomic characteristics, especially weight of stover per clump in wet and dry conditions; stover productivity in wet and dry conditions, but had no significant effect on plant height 3 and 5 WAP, number of tillers per clump, and diameter. The Srikayang variety produced lower productivity than the Crok Kuning and Tajuk varieties. Increasing the width of the spacing will reduce the productivity of shallots.

The success of shallot cultivation in vertisol soil is influenced by the use of seeds and the application of organic matter. This aim of this study aims to determine was to the effect of local organic matter on vertisol soil on the growth and yield of three true shallot seed (TSS) varieties. The research was carried out in Plembutan, Playen, Gunung Kidul. The research was conducted from May-August 2021. The research method used a Split Plot Design with 3 replications. The main plot consists of types of local organic matter (B), consisting of B1 = Cow, and B2 = Goat, B3 = Chicken. While the sub-plots were Varieties (V), consisting of: V1 = Maserati, V2 = Sanren, and V3 = Lokananta. Plant height, number of leaves, number of bulbs per clump, dry bulb weight per clump, bulb diameter, and productivity were all measured. The data was analyzed using variance and DMRT 5%.The results showed that the type of local organic matter did not significantly interact with the TSS variety. Plant height, number of leaves, number of tubers per clump, dry tuber weight per clump, tuber diameter, and productivity were not affected by the organic matter and variety treatments. The type of local organic matter from cows produces the highest growth and yields, followed by goats and chickens. The lokananta variety produced the highest productivity, followed by Sanren and Maserati.

One of the keys to successful shallot cultivation with True Seed of Shallot (TSS) is determined by viability and vigor at the nursery. The aim of the study was to determine the effect of varieties and types of natural Plant Growth Regulatory (PGR) on germination and TSS vigor index. The study was conducted at the Seed Technology Laboratory of the Agricultural Development Polytechnic of Yogyakarta Magelang in July 2021 using a factorial Completely Randomized Design (CRD). The first factor is shallot variety (V) consisting of 3 levels: V1 = Sanren, V2 = Maserati, and V3 = Lokananta. The second factor is Types of Natural plant Growth Regulators (Z) consisting of 4 types: Z0 = aquadest, Z1 = Shallot Extract, Z2 = bean sprout extract, and Z3 = young coconut water. Each treatment was repeated 3 times. Parameters observed were germination, growth speed and vigor index. Data analysis was carried out using a variance test (F test) and Duncan's multiple distance test (DMRT) with a level of 0.05. The results showed that the TSS variety significantly affected germination and growth speed. The type of natural PGR did not significantly affect the germination, but it did affect the growth speed. TSS varieties and natural PGR types significantly interacted with the vigor index parameter. The best vigor index was achieved when the Lokananta variety was treated with distilled water. Keywords: Shallot, bean sprouts, coconut water, germination, vigor.
