Penggunaan Beberapa Jenis Penahan Air untuk Mendukung Pertumbuhan Bibit Jabon Putih (Anthocephalus cadamba) pada Lahan Kritis

Abstract

KHAIRANI REZEKI : Use some type of water retaining to support the growth of white jabon seedlings (Anthocephalus cadamba). Under the supervision of BUDI UTOMO and AFIFFUDDIN DALIMUNTHE. Water is an important factor to supporting the growth of a plants. Lack of water will disturb the physiological and morphological activities, became an atrophy. The purpose of this study is to evaluate the effect of various type of water retaining material appropriate to see influence growth of white jabon seedlings (Anthocephalus cadamba). The research was conducted in October 2013 through February 2014 in the village Pamuntaran, Sihapas Julu district, northern district of Padang Lawas and this study uses a non-factorial completely randomized design with 15 treatments and 3 replications. The parameters analyzed were height, diameter, and number of leaves. The results showed that with briquettes of fertilizer application .The result of this study showed that the type of water retaining to give tangible effect to height and diametres. In average use some of water retaining influence to change height of jabon seedlings in M1 (compost) as highest is 1,86 cms. In average use some of water retaining influence to change lowest of jabon seedlings in M0 (control) is 0,23 cms.In average use some of water retaining influence to change diametres of jabon seedlings in M2 (manure) as highest is 0.17 cms. In average use some of water retaining influence to change diameters of jabon seedlings in M0 (control) as lowest is 0.17 mms. The most potentially kind of water retaining that can saving water is compost and manure.
