Abstract

This study aims to determine growth and yield of onion by administering bokashi fertilizer and organic fertilizer liquid waste banana stems, which are conducted at Farmers Group Community Unite, Hamlet XXII cottage Rowo Village Sampali, District Percut Sei Tuan, Deli Serdang with altitude of 12 m above sea level and flat topography and alluvial soil types. The research was conducted from April to July 2019.The method used in this study is a randomized block design (RBD) in factorial, with 2 (two) treatment factors, Namely: 1) Factors Bokashi fertilizers (B), which consists of 4 levels, namely: B0 = control (no treatment); B1 = Bokashi fertilizer with a dose of 7.5 ton / ha (20 g / polibag); B2 = Bokashi fertilizer with a dose of 15 ton / ha (40 g / polibag); B3 = Bokashi fertilizer with a dose of 22.5 tonnes / ha (60 g / polibag); 2) Organic Liquid Fertilizer treatment factor (POC) Waste Banana Stems (P), which consists of 4 levels, namely: P0 = control (no treatment); P1 = POC Banana Stem 45 ml / l; P2 = POC Banana Stem 90 ml / l; P3 = POC Banana Stem 135 ml / l, each treatment was repeated two (2) times so that there are 32 experimental plots. Each experimental plot consisted of 5 plants with 3 plant samples. The parameters were observed in this study consisted of plant height, number of leaves, plant fresh weight per sample.From the research has been carried out can be concluded as follows: 1) The provision of Bokashi fertilizer significantly affected plant height, plant fresh weight per sample, plant dry weight per sample, weight dry plants per plot but no real effect on the number of leaves of onion plants; 2) Provision of POC waste banana stems provide no real effect on plant height, number of leaves, plant fresh weight per sample, plant dry weight per sample and weight of dried plants per plot onion plants; 3) The combination of Bokashi fertilizer and banana stem waste POC no real effect on the growth and yield of onion and the effectiveness of each treatment and combination treatment is highly effective against onion crop.
