Penelitian ini bertujuan untuk upaya peningkatan produksi dan hasil budidaya tanaman bawang merah yang berwawasan lingkungan dengan pemanfaatan pupuk kandang sapi dan pengaturan jarak tanam.Penelitian dilaksanakan selama 8 bulan daribulan Januari sampai dengan Agustus 2015.Penelitian dilakukan di lahan sawah Brebes, Kabupaten Brebes, jenis tanah alluvial dengan ketinggian tempat kurang lebih 50 m dpl. Penelitian ini merupakan percobaan faktorial 4 x 3 dengan rancangan lingkungan adalah rancangan acak kelompok. Faktor pertama adalah Jarak Tanam : J1 = 20 cm x 20 cm, J2 = 20 cm x 15 cm, J3 = 20 cm x 10 cm. Faktor yang kedua adalah takaran pupuk kandang sapi yaitu K0 = 0ton/ha, K1 = 10 ton/ha, K2 = 20 ton/ha, K3 = 30 ton/ha. Data hasil pengamatan dianalisis dengan uji F untuk mengetahui keragamannya dan apabila ada perbedaan nyata dilanjutkan dengan DMRT dengan tingkat kesalahan 5%. Hasil penelitian menunjukkan bahwa hasil umbi segar dan kering bawang merah per hektar terbanyak diperoleh pada tanaman dengan perlakuan jarak tanam 20 x 15 cm dengan hasil 20,56 t/ha (umbi segar) dan 18,63 t/ha (umbi kering).Kata kunci : bawang merah, jarak tanam, pupuk kandang[U1] sapi [U1]pupuk kandang sapi

This research was donewithin 8 months since January until August 2015. This research was done in Brebe with characters of alluvial soiland place hight is less than 50 m above sea level. This research arranged by factorial with first factor of plantdistance viz. J1= 20 cm x 20 cm, J2= 20 cm x 15 cm, J3= 20 cm x 10 cm and second factor of cow manure dosageviz. K0 = 0 to/ha, K2 = 20 ton/ ha, K3 = 30 ton/ha. The character of growth and yield of shallots was observed inthis study.Data of observing result analized by F test and it will be continued by DMRT p= 5% if there wassignificant difference. Research result showed that the highest wet tuber and dry shallot per hectare mostly foundon plant distance 20 x 15 cm with the result of 20.56 t/ha and 18.63 t/ha, respectively.Keywords: shallot, plant distance, cow manure, growth and yield
Abstract. Juwanda M, Sakhidin, Saparso, Kharisun. 2020. Soil properties and sulfur-oxidizing bacterial diversity in response to different planting patterns of shallot (Allium ascalonicum). Biodiversitas 21: 2832-2839. Sulfur is one of the primary elements required by plants for growth and development. Sulfur-oxidizing bacteria (SOB) can oxidize sulfur to sulfate, which is directly taken up by plant roots. This study aims to evaluate the soil properties and SOB diversity in various shallot planting patterns, i.e. PP1 (shallot-dry season-shallot-shallot), PP2 (shallot-dry season-shallot-rice), and PP3 (shallot-pulses-shallot-rice). Soil samples were collected from the rhizosphere of the shallot plant and analyzed for the soil properties based on the standard methods. Bacteria isolation was cultured on Starkey broth and Starkey agar. Bacteria isolate was identified based on the 16S rRNA gene sequence and compared to the GenBank database. The results showed that shallot planting patterns influence soil properties and SOB diversity. The highest content of sulfate (41.31 ppm), organic C (0.957 %), organic matter (1.650%), C/N ratio (9.57), and SOB diversity was obtained in PP3 planting pattern. Three bacterial strains have been successfully isolated i.e. A-3245D, B-3246F, and C-3247C with their closest related to Burkholderia cepacia, Klebsiella variicola, and Klebsiella aerogenes, respectively. The highest diversity and population density of SOB was in the PP3 planting patterns, i.e Burkholderia cepacia (7.45 x 105 CFU/mL); Klebsiella variicola (1.79 x 107 CFU/mL; Klebsiella aerogenes: 3.9 x 106 CFU/mL). K. variicola can be found in three planting patterns of shallot.
Compost is a solid organic material that biologically changes into a final product that can be used as fertilizer. Utilizing shallot leaf waste as raw material for composting is the latest technology and has never been applied by shallot farmers. This study aimed to determine the best quality of shallot leaf compost with the long treatment of the composting process. This process was supported through Trichoderma, sp activator with 106 cfu/mL density. The treatment design was arranged as follows: K0 = no composting (leaves were simply dried in the sun), K1 = composting for 1 day, K2 = composting for 2 days, K3 = composting for 3 days, K4 = composting for 4 days, K5 = composting for 5 days, K6 = composting for 6 days, K7 = composting for 7 days, K8 = composting for 14 days, K9 = composting for 21 days, and K10 = composting for 28 days. The data were analyzed descriptively. The results showed that the shallot leaf waste with the composting process was dried by the sunlight (natural composting) and had a C/N ratio. Meanwhile, the C-organic and N-total of this composting process were better than that of composting using a solution containing Trichoderma sp. activator.
