Abstract

ABSTRAK. Kebiasaan penanaman bawang daun oleh petani di Indonesia menggunakan anakan, induk, dan hampir tidak ada yang menggunakan biji. Pengiriman bibit ke luar daerah sering mengalami kerusakan sebelum sampai ke tempat tujuan. Percobaan ini bertujuan mengetahui pengaruh enzim organik campuran guna mengetahui pengaruhnya terhadap daya simpan bibit bawang daun. Percobaan dilakukan di Laboratorium Teknologi Benih Balai Penelitian Tanaman Sayuran di Lembang (1.250 m dpl), Jawa Barat, pada bulan Agustus sampai Desember 2005 untuk penyimpanan dan di lapangan untuk tes pertumbuhan. Penelitian menggunakan rancangan acak lengkap untuk di laboratorium dan acak kelompok untuk di lapangan, dengan model rancangan petak-petak terpisah dengan 3 ulangan. Kombinasi perlakuan ada 24, rincian perlakuan terdiri atas media simpan (petak utama): A (A1= pembanding/tanpa menggunakan media/kering, A2=kontrol/menggunakan air, A3=Dufic 0,1 ml/l air, A4=Dufic 0,2 ml/l air), ukuran bibit (anak petak): B (B1=super/ panjang batang palsu >15 cm dan diameternya >15 mm, B2=medium/panjang batang palsu 10-15 cm, dan diameter batang 10-15 mm dan B3=kecil atau pendek/panjang batang palsu <10cm, dan diameter batang <10 mm), lokasi penyimpanan (anak-anak petak): C (C1=tempat terbuka/greenhouse, C2=tempat tertutup/Laboratorium Benih). Hasil percobaan menunjukkan bahwa bibit bawang daun dapat disimpan maksimum 6 hari dengan syarat batangnya tidak terendam larutan Dufic 508 dosis 0,1 ml/l air dan bibit yang ukurannya besar mampu menstimulir aktivasi metabolisme sel dalam bentuk rendahnya kerusakan bibit dan berpengaruhnya terhadap partumbuhan tinggi tanaman. Interaksi perlakuan terbaik adalah penggunaan Dufic 508 dosis 0,1 ml/l air dan ukuran bibit super yang disimpan di dalam ruangan tertutup.ABSTRACT, Soedomo, R.P. 2006. The effect of organic enzyme mixture on bunching onions planting material quality in storage. Commonly Indonesian farmers use sucker of bunching onion as a planting material and never use seeds. Planting material transportation outside region encountered damages before reached the destination. The objective of this trial was to determine the effect of mixture of organic enzyme (Dufic 508) on bunching onions planting material storage quality. The experiment was carried out in the laboratory of Seed Technology and in the field of Indonesian Vegetable Research Institutes (1,250 m asl), West Java, from August to December 2005. The experimental design was a RBD for seed laboratory study and a RCBD for field test, a split split plot design with 3 replications. The treatment combinations were: keeping media (main plot) (A1=standard/without media/dry, A2=control/used water, A3=Dufic 0.1 ml/l of water, A4=Dufic 0.2 ml/1 of water), B. Planting material size (subplot) (B1=super/length of stem >15 cm and diameter > 15mm, B2 = Medium/length of stem 10-15 cm and diameter 10-15 mm, B3=small or short/stem <10 cm and diameter <10 mm), C. Storage (subsubplot) (C1=open storage/greenhouse, C2=close storage in the seed laboratory). The results showed that the planting material of bunching onion could be kept maximum for 6 days with unsoaked stem, Dufic 508 dosage 0.1 ml/1 liter of water in combination with super size of planting material could stimulate metabolism activation of plant cells described by decreasing of planting material damages and increasing of plant height.

Abstract

ABSTRAK. Di Indonesia bawang putih sudah merupakan bumbu masakan yang merakyat. Untuk konsumsi saat ini sebagian besar umbi berasal dari impor, padahal banyak daerah dataran tinggi di Indonesia yang sangat baik untuk penanaman bawang putih. Penelitian ini bertujuan mengetahui jenis pengemas yang terbaik guna memperpanjang daya simpan umbi bibit bawang putih serta pertumbuhan dan hasil di lapangan. Percobaan telah dilakukan di Laboratorium Benih, Balai Penelitian Tanaman Sayuran, Lembang (1.250 m dpl), pada bulan Oktober 2004–Februari 2005. Penelitian dilanjutkan di lapangan untuk observasi terhadap penampilan umbi bibit. Rancangan yang digunakan adalah acak lengkap untuk penelitian di laboratorium benih dan acak kelompok untuk penelitian di lapangan, dengan model rancangan petak terpisah, terdiri atas 4 ulangan dan 7 perlakuan. Perlakuan terdiri dari (1) kantong plastik + batu kapur, (2) kantong plastik + batu kapur (CaCO3) + O2, (3) kantong plastik + Aquastore, (4) kantong plastik + Aquastore + O2, (5) rajut plastik, (6) kantong kertas semen + batu kapur, dan (7) kantong kertas semen + Aquastore. Hasil menunjukkan bahwa pengemasan umbi bibit bawang putih yang berdampak terhadap pertumbuhan dan hasil terbaik adalah penggunaan jaring plastik dengan daya simpan 57 hari dan kerusakan 9,6%. Di lapangan tinggi tanaman pada umur 14, 28, 42, 56, dan 70 HST masing-masing adalah 6,00; 12,23; 30,00; 40,75; dan 49,0 cm, dengan daya tumbuh 87,60%. Bobot hasil per lubang tanaman 80,80 g, dan siung per umbi 10,80 buah, dan diameter umbi lapis 32,10 cm. Pengemas dalam kondisi tertutup dapat menggunakan kertas semen, dengan penyerap batu kapur maupun Aquastore, dengan nilai kerusakan pada penyimpanan masing-masing adalah 12,5 dan 11,00%, dan daya simpan masing-masing 62,0 hari.

Effect of packaging materials on the keeping quality of seedbulbs, the growth, and yield performance of garlic. Garlic as cooking spices was widely used in Indonesia. Most of the garlic consumed was imported in fact that some potential higlands suitable for planting garlics were ignored. The objectives of the study were to find out the best packaging materials for seed bulbs and its impact to growth and yield in the field. The trial was conducted at the seed laboratory of Indonesian Vegetable Research Institute at Lembang (1,250 m asl) in October 2004-February 2005. The subsequent planting was done in the research field of the institute to observe the performance of the seedbulbs. The experimental design was CRD for storage laboratory study and RCBD for field observation, with a split plot design. There were 7 treatments and 4 replications. The treatments were (1) polyethylene wrap + CaCO3, (2) polyethylene wrap + CaCO3 + O2, (3) polyethylene wrap + Aquastore, (4) polyethylene wrap + Aquastore + O2, (5) polyethylene plastic net, (6) cement paper bag + CaCO3, and (7) cement paper bag + Aquastore. The results showed that the best packaging material was plastic net with seed bulb damages of 9.6%, and storage life of 57 days. The plant height at 14, 28, 42, 56, and 70 days after planting (dap) were 6.00, 12.23, 30.00, 40.75, and 49.0 cm respectively. The yield per plant was 80.80 g. Number of bulblet per bulb was 10.80, and diameter of bulb was 32.10 cm. Cement paper, with absorber materials of limestone and Aquastore showed damages of 12.5 and 11.0% respectively. The keeping quality stood for 62.0 days. The plant height at 14, 28, 42, 56, and 70 dap were 6.90, 12.60, 30.90, 41.15, and 49.27 cm (limestone absorber), and 8.43, 14.50, 32.25, 42.50, and 51.80 cm (Aquastore absorber) respectively. The plant survival in the field were 92.80 and 97.90%. The number of bulblets were 78.60 (limestone) and 77.70 (Aquastore).
