Efektivitas Pemberian Pupuk Hijau Paitan (Tithonia diversifolia) dan Pupuk Kandang Sapi Terhadap Pertumbuhan Bibit Pisang FHIA-17

Abstract

This study aims to look at the effect of application of Paitan (Tithonia diversifolia) green fertilizer and Cow manure on the growth of FHIA-17 banana seedling, which was carried out at the expremental garden of the faculty of agriculture, medan area university jalan kolam no.1 medan estate, percut sei tuan district with 22 M above sea level , flat Topography and Alluvial Soil Type This Research Begins From May To July 2018. The design used in this study was Factorial Randomized Block Design with two treatment Factors. 1) Treatment of Paitan (Tithonia diversifolia) green fertilizer consists of five levels of treatment,namely, P0 = Only soil (Control); P1 = 12,5 g/5 kg of planting medium (equivalent to 5 tons ha-1); P2 = 25 g/5 kg of planting medium (equivalent to 10 tons ha-1); P3 = 37,5 g/5 kg of planting medium (equivalent to 15 tons ha-1); P4 = 50 g/5 kg (equivalent to 20 tons ha-1); and 2) Treatment of Cow manure consists of five levels of treatment,namely, K0 = Only soil (Control); K1 = 12,5 g/5 kg of planting medium (equivalent to 5 tons ha-1); K2 = 25 g/kg of planting medium (equivalent to 10 tons ha-1) K3 = 37,5 g/5 kg of planting medium (equivalent to 15 tons ha-1) K4 = 50 g/5 kg (equivalent to 20 tons ha-1); and repeated twice, Parameter observed in this study are : plant height (cm), number of leaves, stem circumference (cm), plant wet weight (g), plant dry weight (g). The results of this study indicate that : Giving of Paitan (Tithonia diversifolia) green fertilizer significantly affects plant height and number of leaves; The provision of Cow manure had no significant effect on all observation parameters; and there are interactions between
