pengaruh varietas dan jarak tanam pada budidaya bawang merah asal biji true Shallot seeds tss di kabupaten bantaeng
Jurnal Pengkajian dan Pengembangan Teknologi Pertanian, 2020Co-Authors: Maintang Intang Marzuki, Abdul Wahid Rauf, Asriyanti Ilyas, Sarintang Sarintang, Riswita SyamsuriAbstract:The Influence of Varieties and Spacing on Shallot Cultivation from Seeds (True Shallot Seeds/TSS) in Bantaeng District. Plant population density affects the competition between plants to growth factors so that it will have an impact on the yield of Shallots from true Shallots seed (TSS). This study aimed to determine the appropriate spacing for growth and tuber yield of some Shallots varieties from TSS. The study was carried out on the dry land of Bonto Mate’ne Village, Sinoa District, Bantaeng Regency – South Sulawesi, from October - December 2017. The experiment used a split plot design with three replications. Two spacing (J1 = 10x10 (cm), J2 = 15 x 15 (cm)) were placed as the main plot and three varieties (Trisula (V1), Bima Brebes (V2) and Tuk Tuk (V3)) as subplots. The results showed that the interaction between varieties and spacing did not affect the growth and yield of Shallots from TSS. The differences in spacing showed a significant effect on the number of leaves aged 45 HST and the number of tillers aged 30 and 60 HST. The spacing of 10 x 10 (cm) showed a higher average growth with tuber production of 7.38 t/ha. Bima variety showed higher plant growth, number of leaves and number of tillers and significantly different from Tuk-Tuk and Trident and gave higher tuber yield (7.45 t / h) followed by Tuk-Tuk (7.10 t/h) and Trident varieties (7.03 t/h). cultivation of Shallots from seeds was more beneficial compared to farming onions from tubers, but the two farms are still worth the effort with R/C > 1. Keywords : Shallot, varieties, true Shallot seeds, spacing ABSTRAK Kerapatan populasi tanaman mempengaruhi tingkat kompetisi antar tanaman terhadap faktor tumbuh sehingga akan berdampak pada hasil tanaman bawang merah asal true Shallots seed (TSS). Penelitian ini bertujuan untuk mengetahui jarak tanam yang tepat untuk pertumbuhan dan hasil umbi beberapa varietas bawang merah dari TSS. Penelitian dilakukan pada lahan kering Desa Bonto Mate’ne, Kecamatan Sinoa, Kabupaten Bantaeng-Sulawesi Selatan, dari Oktober – Desember 2017. Penelitian menggunakan rancangan petak terpisah dengan tiga ulangan. Dua jarak tanam (J1= 10x 10 (cm), J2 = 15 x 15 (cm)) ditempatkan sebagai petak utama dan tiga varietas (Trisula (V1), Bima Brebes (V2) dan Tuk tuk (V3)) sebagai anak petak. Hasil penelitian menunjukkan interaksi antara varietas dan jarak tanam tidak berpengaruh terhadap pertumbuhan dan hasil umbi bawang merah asal TSS. Perbedaan jarak tanam menunjukkan pengaruh nyata pada jumlah daun umur 45 HST serta pada jumlah anakan umur 30 dan 60 HST. Jarak tanam 10 x 10 (cm) menunjukkan rerata pertumbuhan yang lebih tinggi dengan produksi umbi 7,38 t/ha. Varietas Bima menunjukkan pertumbuhan tinggi tanaman, jumlah daun dan jumlah anakan yang lebih tinggi, berbeda nyata dengan Tuk-tuk dan Trisula serta memberikan hasil umbi lebih tinggi (7,45 t/h) disusul oleh varietas Tuk-Tuk (7,10 t/h) dan Trisula (7,03 t/h). Usahatani bawang merah dari biji lebih menguntungkan di bandingkan dengan usahatani bawang merah dari umbi, namun kedua usahatani tersebut masih layak di usahakan dengan Nilai R/C >1.

conservation agriculture a selective model based on emergy analysis for sustainable production of Shallot as a medicinal industrial plant
Journal of Cleaner Production, 2021Co-Authors: Zahra Amiri, Mohammad Reza Asgharipour, Daniel E Campbell, Khosrow Azizi, Ebrahim Kakolvand, Esfandiar Hassani MoghadamAbstract:Abstract In addition to achieving of food security in the long-run, the identification and introduction of sustainable ecosystems is associated with the protection of natural resources and the provision of environmental services that flow from those resources. A paradigm for the production of Shallots has arisen in the agroecosystems of Iran to prevent the extinction of the Shallot plant, on one hand, and to meet the market demand for this valuable medicinal-industrial product, on the other. This study aimed to identify the most sustainable Shallot production system by comparing mechanized, traditional, and conservation Shallot production systems with the growth of this plant in its natural habitat in Selseleh County, Iran, during 2018–2019. The analysis was done by calculating net emergy of each system and by reviewing 14 different emergy indices. Soil conservation is very important in the sustainability of agroecosystems. In this regard, a positive evaluation of the energy input structures in a conservation system is based on the soil stability of that system. The results showed that the status of a protected system is optimal based on the values of the Unit Emergy Value (UEV = 6.62E+05 sej J−1), Specific emergy (SE = 7.05E+09 sej g−1), Inverse emergy exchange ratio (IEER = 0.942), and Emergy index of product safety (EIPS = 1) indices and, to some extent, on Renewable emergy ratio (R%), Modified version of the environmental sustainability index (ESI∗), Modified version of the environmental loading ratio (ELR∗), and Emergy invested per $ net profit (EINPR). As a result, the most optimal system was found by increasing the amount of the free environmental renewable input flow (R). The optimal EINPR, Economic emergy efficiency (EEE) and IEER values of the natural habitat indicate the risk of overharvesting Shallots from this system, which necessitates paying more attention to protecting the ecosystem and preventing overharvesting. Although a number of indices showed the advantage of the mechanized Shallot production system over the other two agroecosystems. However, since an important part of the desirability of a mode of production implied by these indices is related to the share of free environmental inputs that are used in a renewable manner, modes of production that rely heavily on the non-renewable use of free environmental flows and result in soil instability are not preferred, thus a mechanized system is not recommended as the first choice for Shallot production. The equality of the EIPS index both in conservation and in natural systems showed the high quality of the crop in the conservation system among the studied crop systems.
