Jayati, Ela Dwining Nur (2017) Produktivitas Beberapa Tanaman Leguminosae Lokal Pionir Tumbuh Di Media Tanah Kritis Pasca Pertambangan Batubara Dan Abu Vulkanik. Sarjana thesis, Universitas Brawijaya.
Abstract
Tujuan dari penelitian ini adalah membandingkan respon perkecambahan, pertumbuhan bagian akar dan atas, bintil akar, serta menentukan adaptasi dan produktivitas tanaman Leguminosae lokal pionir di tiga media tanam. Spesies Leguminosae yang digunakan yaitu Desmodium triflorum, Tamarindus indica, Crotalaria pallida, Cajanus cajan, Adenanthera pavonina dan Sesbania grandiflora. Perlakuan diulang sebanyak dua kali, sehingga didapatkan 36 kombinasi perlakuan. Masing-masing spesies ditanam dalam media mulsa hydroseeding yang diletakkan di atas tanah kebun Universitas Brawijaya (UB), tanah pasca tambang, dan abu vulkanik. Hasil penelitian menunjukkan bahwa spesies yang mampu berkecambah dan tumbuh di tiga media tersebut adalah S. grandiflora, D. triflorum, A. pavonina, dan C. pallida, sedangkan T. indica dan C. cajan gagal berkecambah. Rasio panjang akar dan bagian atas tanaman bervariasi antar spesies dan tertinggi diamati pada A. pavonina tumbuh di abu vulkanik. Jumlah bintil akar paling tinggi diamati pada S. grandiflora di tanah kebun UB. Adaptasi ke empat spesies yang ditanam di tiga media menunjukkan respon yang bervariasi. Produktivitas bagian atas tanaman lebih tinggi daripada produktivitas bagian akar. Produktivitas total tanaman tertinggi terdapat pada spesies A. pavonina yang ditanam di media abu. Aplikasi hydroseeding empat spesies Leguminosae mampu memperbaiki pH, konduktivitas, dan bahan organik tanah.
English Abstract
Aims of this study are to compare response germination, root and shoot growth local pioneers Leguminosae, nodule as well as to determine their adaptation, and productivity on three media. Leguminosae studied were Desmodium triflorum, Tamarindus indica, Crotalaria pallida, Cajanus cajan, Adenanthera pavonina and Sesbania grandiflora. Each treatment was repeated twice, therefore there were 36 combinations treatment. Each species seed was planted in the garden soil Universitas Brawijaya (UB), post-mining, and volcanic ash. Result sowed S. grandiflora, D. triflorum, A. pavonina, and C. pallida sucessfully germinated and grow in all media, whereas T. indica and C. cajan were failed. The root/shoot ratio varied among the highest was A. pavonina grown in volcanic ash media. The highest numbers of nodules was observed on the S. grandiflora on garden soil of UB. Adaptation of four on all media shows a varied. The shoot productivity of all species was higher than the root are the highest total productivity was found A. pavonina grown in volcanic ash media. Application of hydroseeding using four species improved the upland soil especially soil pH, conductivity, and organic matter.
