Respon Pertumbuhan dan Produksi Bawang Merah (Allium ascalonicum L) Terhadap Pemberian Urin Sapi dan Limbah Brassica

Abstract

Research on growth and onion (Allium ascalonicum L) production response to cow urine and brassica waste conducted in experimental garden of Faculty of Agriculture Universitas Medan Area, Kolam street no. 1 Medan Estate, Percut Sei Tuan District with a height of 25 meters above sea level (asl) from May to July. The purpose of this research is to know the response of growth and production of onion (Allium ascalonicum L.) to application of cow urine and Brassica waste. This research was conducted by using Factorial Random Block Design which consists of two factors: Factor I: Treatment of Cow Urine Concentration consisting of 4 levels with each concentration is ; U0 = NPK fertilizer 40g / plot (400 kg / ha), U1 = Urine 25% / Liter water, U2 = 50% cattle Urine / Liter water, U3 = Cow urine 75% / Liter water. Factor II: The treatment of Brassica waste consisting of 3 levels with each doseis; B0 = Brassica waste 0 Kg / plot, B1 = Brassica waste 1 Kg / plot, B2 = Brassica waste 2 Kg / plot. The parameters observed in this study were plant height (cm), number of leaf per hill (piece), tuber weight per sample (g), tuber weight per plot (g), tuber weight per sample (g) Drying per plot (g), the percentage of oxysporum fusarium attack. The results showed that the actual cow urine content to wet weight per plot with the best concentration was U0 = NPK 40g / plot (control), real weight per plot with the best concentration of U0 = fertilizer NPK 40g / Plot (control). Brassica waste significantly affected wet weight per plot with the best concentration of B1, 1 Kg / plot brassica waste and significantly increased dry weight per plot with the best concentration of B, brassica waste 1 Kg / plot. The interaction of cow urine and brassica waste treatment significantly increased wet weight per plot with the best concentration of U0B1 = NPK 40g / plot (control) and B1 = Brassica 1 Kg / plot waste and dry weight per plot with the best concentration of U0B1 = Ie NPK 40g / plot (control) and B1 = Waste Brassica 1 Kg / plot. The interaction of cow urine and brassica waste had no significant effect on leaf height, leaf number, sample wet weight and dry weight of the sample. However, significant effect on wet weight per plot and dry weight per plot.
