Respon Pertumbuhan dan Poduksi Bawang Merah (Allium ascalonicum L.) pada Konsentrasi Air Kelapa dan Lama Perendaman Umbi

Response of growth and production of onion (Allium ascalonicum L.) on concentration of coconut water and tuber soaking time

Abstract

Permintaan bawang merah terus meningkat sejalan dengan peningkatan jumlah penduduk dan kebutuhan konsumsi bawang merah masyarakat.Penelitian ini dilaksanakan di Desa Tanjung Anom, Perumahan Purwojoyo mulaibulanNovember2015 sampai dengan Januari 2016, menggunakan Rancangan Acak Kelompok dengan 2 Faktor perlakuan. Faktor pertama adalah Konsentrasi air kelapa {(25% (250ml air kelapadalam 750 ml air); 50% (500 ml air kelapa dalam 500 ml air); 75% (750 ml air kelapa dalam 250 ml air); 100% (1000 ml air kelapa)}dan faktor kedua yaitu Lama perendaman (2, 4 dan 6 jam). Parameter yang diamati adalah panjang tanaman, jumlah daun per rumpun, jumlah siung per sampel, bobot basah umbi per sampel, bobot basah umbi per plot, bobot kering jual umbi per sampel, dan bobot kering jualumbi per plot. Hasil penelitian menunjukkan bahwa konsentrasi air kelapa tidak berpengaruh nyata terhadap semua parameter pengamatan. Lama perendaman berpengaruh nyata terhadap tinggi tanaman 2, 3, 4, 6 dan 7 MST bobot basah umbi per sampel, bobot basah umbi per plot , bobot kering jual umbi per plot. Interaksi antara konsentrasi air kelapa dengan lama perendaman tidak ada interaksi terhadap semua parameter pengamatan.

Demand onion increased with increasing population and the consumption needs of society. One of the efforts to increase the productivity of onion with technology improvements.This research was conducted in Desa Tanjung Anom, Purwojoyo housing began from November 2015 to January 2016. This research used factorial randomized block design with two factors. The first factor was concentration of coconut water {(25 % ( 250 ml coconut water in 750 ml of water ); 50 % ( 500 ml coconut water in 500 ml of water ); 75 % ( 750 ml coconut water in 250 ml of water ); 100 % ( 1000 ml coconut water)} and the second factor was tuber soakng time (2, 4 and 6 hours). Parameter observed was plant length , number of leaves per clump , number of cloves , tuber fresh weight , tuber fresh weight per plot , selling dry weight of tubers , and dry weight of tuber per plot . The result of this research showed that concentration of coconut water were not significantly effect to all parameters. Soaking time were significantly effect to plant length parameter 2,3,4,6,and 7 weeks after planting, tuber fresh weight per sample, weight of tuber per plot. Interaction of varieties and application various of potassium source were not significantly effect to all parameters.
