Pengaruh Konsentrasi Air Kelapa dan Lama Perendaman terhadap Pertumbuhan dan Produksi Bawang Merah Varietas Tuk Tuk (Allium ascalonicum L.) Asal Biji

Effect of coconut water concentration and the duration of true shallot seed soaking on growth and production of shallot (Allium ascalonicum L.) of Tuk-Tuk varieties

Abstract

This research was conducted to find out the effect of coconut water concentration and the duration of true shallot seed soaking on the growth and production of shallot. This research was conducted on community farm at Jalan Bunga Rampai II Gang Saudara, Kelurahan Simalingkar B, Kecamatan Medan Tuntungan, Medan, began from April to August 2017. The research used a Factorial Randomized Block Design with 2 treatment factors: coconut water concentration at 5 levels: 0; 25; 50; 75; 100 %, and duration of seed soaking at 3 levels: 60; 120; 180 minutes. The parameters observed were number of plant height at 2 to 7 weeks after transplanting (WAT), bulb diameter, and dry bulb weight. The result of this research showed that coconut water concentration had no significant effect on all observation parameter. The duration of seed soaking treatment had significant effect on plant height and dry bulb weight. The highest dry bulb weight was obtained at 120 minutes of seed soaking. The interaction of coconut water concentration and the duration of true shallot seed soaking treatment had no significant effect on all observation parameters.

Penelitian ini dilakukan untuk mengetahui pengaruh konsentrasi air kelapa dan lama perendaman terhadap pertumbuhan dan produksi bawang merah asal biji. Penelitian ini dilaksanakan di lahan pertanian masyarakat yang terletak di Jalan Bunga Rampai II Gang Saudara, Kelurahan Simalingkar B, Kecamatan Medan Tuntungan, Medan, mulai bulan April sampai dengan Agustus 2017. Penelitian menggunakan Rancangan Acak Kelompok faktorial dengan 2 faktor perlakuan yaitu konsentrasi air kelapa pada 5 taraf: 0; 25; 50; 75; 100 % dan lama perendaman pada 3 taraf: 60; 120; 180 menit. Parameter yang diamati adalah panjang tanaman 2–7 minggu setelah pindah tanam (MSPT), diameter umbi, dan bobot kering umbi. Hasil penelitian menunjukkan bahwa konsentrasi air kelapa berpengaruh tidak nyata terhadap semua parameter pengamatan. Perlakuan lama perendaman berpengaruh nyata terhadap parameter panjang tanaman dan bobot kering umbi. Bobot kering umbi tertinggi diperoleh pada lama perendaman 120 menit. Interaksi antara konsentrasi air kelapa dan lama perendaman berpengaruh tidak nyata terhadap semua parameter pengamatan.
