Respon Pertumbuhan dan Produksi Tanaman Pakcoy (Brassica RapaL.) yang Diberi Pupuk Organik

Abstract

This research was conducted in the experimental garden of the Faculty of Agriculture, University of Medan Area, Jl. Kolam No. 1, Medan Estate, Percut Sei Tuan Sub-District, with a height of 12 meters above sea level, and carried out from December 2017 to January 2018. The research method used was Non Factorial Randomized Block Design (RBD), with 7 levels of treatment factors, namely : P0 = Control (NPK fertilizer 16, 16, 16 with a dose of 200Kg/ha); P1 = Cow Manure dose 5 tons/ha (0,5 Kg/m2); P2 = Cow Manure dose 10 tons/ha (1 kg/m2); P3 = Cow Manure dose 15 tons/ha (1,5 Kg/m2); P4 = Cabbage Waste Compost dose 5 tons/ha (0,5 Kg/m2); P5 = Cabbage Waste Compost dose 10 tons/ha (1 Kg/m2); and P6 = Cabbage Waste Compost dose 15 tons/ha (1,5 Kg/m2). This research was repeated 4 times. Parameters observed in this study were plant height, number of levels gross weight of production a sample, gross weight of production a plot, net weight of production a sample, and net weight of production. The results obtained from this reseacrh are : 1) Giving Cow Manure and Cabbage Waste Compost significantly affect plant height, gross production/sample weight, production/plot gross weight, net production/sample weight and net production weight, but not real effect on the amount of pakcoy plant leaves, and 2) Giving of Cow Manure at a dose 1,0 Kg/m2 (P2) is the highest production dose for pakcoy plants.
