Pengaruh Komposisi Media Tanam dan Penutupanparanet terhadap Pertumbuhan Sengon (Paraserianthes falcataria (L.) Nielsen)

Abstract

Sengon or (P. falcataria (L.) Nielsen). including the Leguminoceae family. This plant is very potential to be selected as one of the fast growing species, the management is relatively easy, the wood is strong and the market demand continues to increase, while ecologically Sengon can improve environmental quality such as increasing soil fertility and improving water systems. . The purpose of this research was to determine the composition of a good and correct planting medium in order to obtain maximum plant growth and to determine the effect of seedling cover treatment with paranet on the growth of sengon (P. falcataria (L.) Nielsen). The study was conducted at the Forestry Laboratory of the Faculty. Agriculture-Animal Husbandry University of Muhammadiyah Malang. Observations were made from January to April 2019. This study used a randomized block mix (RAK) which was arranged factorial. The first factor was the composition of the planting medium (P) consisting of 4 levels of top soil and sand media with a ratio of 1: 1 (control), and media for top soil, sand and manure (chicken, goat and cow), with each treatment the ratio was 2: 1: 1. The second factor was paranet cover treatment (M) which consisted of 3 levels of plants without getting paranet cover treatment, plants were treated with paranet cover with a density of 25% and 50%. The variables observed were germination rate, germination rate, seedling growth (diameter, height, number of leaves, wet weight, dry weight, and root length). If the results of the analysis have a significant effect, it will be further tested using the Duncan 5% test. The results of this study indicated that there was no significant interaction with the percentage of germination between the composition of the growing medium and the light intensity treatment on the germination rate variable of sengon (P. falcataria (L.) Nielsen) seedlings. The best treatment of this research is that there is a significant interaction between the composition of the growing media and the treatment of light intensity on the height variable of sengon seedlings (P. falcataria (L.) Nielsen). Topsoil, sand, and goat manure with a ratio of 2: 1: 1 is the most suitable and good planting medium for the growth of sengon (P. falcataria (L.) Nielsen) seedlings. Plant treatment without paranet cover was a good treatment and had a positive effect on the growth of sengon (P. falcataria (L.) Nielsen) seedlings
