Diseminasi Teknologi True Seed of Shallot dan Umbi Mini Bawang Merah di Karangploso, Malang, Jawa Timur

Abstract

Shallots (Allium cepa var. aggregatum) is one of the vegetable commodities whose demand continues to increase in line with population growth. The purpose of this community service program to disseminate the results of research on how to produce true seed of shallot (TSS) then plant TSS to produce mini bulbs as seeds of shallots. The target audience was the farmers group Tani Mulya in Tawangargo Village, Karangploso Sub-District, Malang Regency, East Java. Activities step included preparation, socialization, demonstration plot of shallot bulbs planting to produce TSS and planting TSS, to produce mini bulbs as seeds of shallot. Batu Ijo variety grown to produce TSS, while planting of TSS used Tri Sula and Keta Monca varieties. This activitity was done well according to a Likert scale of 4.3 (good category = 4–4.9). Farmers were able to adopt the technology of TSS production and planting of TSS to produce shallot mini bulbs of seeds, with indication of the production of TSS and mini bulbs. The flowering of shallot plants 55.5 and TSS seed weight 10.16 g/m2. Bulbs seed of Batu Ijo variety produced large bulbs, while TSS from Tri Sula and Keta Monca varieties produced mini bulbs that can be used as seeds. The change of the shallot seeds technology from bulbs to TSS will be economically beneficial, because the TSS required less than bulbs, so the cost difference is quite large. TSS needs 3–5 kg/ha (TSS price IDR 1.200.000/kg), and bulbs seed needs 1–1.5 ton/ha (bulbs price IDR 30.000/kg), so the margin is IDR 24.000.000 per hectare.

Bio-stimulants derived from seaweed enhance true shallot seed (TSS) growth

“…True Shallot Seed (TSS) has been known by Indonesian farmers as an alternative material for propagation of shallots other than bulbs [5]. The advantages of TSS over tuber seeds include the need for less seed; lower seed storage and transport costs, healthier cropping [6] larger tuber size [7], and higher yields and profits [8,9,10]. This is in accordance with the results of studies in shallot farming which states that efficient use of seeds can increase shallot production [11].…”

Rhizophagus intraradices dan Trichoderma asperellum sebagai Bioprotektan dan Biofertilizer pada Bawang Merah TSS

“…Penyebabnya antara lain ialah terbatasnya ketersediaan benih TSS dan belum ditemukannya teknologi pembibitan dan pembudidayaan bawang merah dari TSS yang lebih efisien. Transisi adaptasi teknik budi daya bawang merah dari penggunaan bibit umbi yang relatif mudah beralih menggunakan benih TSS masih sulit di tingkat petani karena budi daya tanaman bawang merah menggunakan benih TSS memerlukan ketekunan pemeliharaan terutama di awal pertumbuhan (Makhziah et al 2019). Oleh karena itu, benih TSS yang baik pada masa persemaian sangat penting dirawat.…”

Pengaruh Konsentrasi Pupuk Silika dan Umur Transplanting terhadap Pertumbuhan dan Hasil Bawang Merah dari Benih True Shallot Seed (TSS)

“…TSS kini menjadi alternatif benih bawang merah ditingkat petani namun masih menemui masalah pada daya tumbuh benih yang rendah, belum ditemukannya teknologi pembibitan bawang merah dari biji, serta dengan biji memerlukan waktu dalam persemaian. Biji TSS mampu berkecambah hingga 60-80 %, akan tetapi jumlah bibit yang berhasil tumbuh sangat rendah (< 50%), serta memerlukan waktu yang lebih lama karena harus melalui persemaian biji selama 4-6 minggu (Makhziah et al, 2019;Simo et al, 2017), dan hasilnya pun masih lebih rendah dibanding umbi (Purba et al, 2020).…”
