Abstract

This study aimed to investigate mycorrhizal colonisation on plant growth and nutrient acquisitions on three crop species, i.e, soybean (Glycine max (L.) Merr cv. Willis), upland rice (Oryza sativa cv. Cirata), and maize (Zea mays cv. Marshall). These crops were inoculated with arbuscular mycorrhiza fungi (AMF) Glomus mosseae BEG 107 grown in a Luvisol (Calcareous soil, pH 7.3 in CaCl2) under glasshouse conditions. Inoculated plants became mycorrhizal while control plants remained non-mycorrhizal. The AM colonisation rates were as high as 60%, 40%, 70% of the total root length, respectively, in soybean, upland rice, and maize. Mycorrhizal crop growth increased 7.5-folds, 4.5-folds, and 5.0-folds relative to non-mycorrhizal crop, respectively, in soybean, upland rice, and maize. Related to nutrient uptake, mycorrhizal colonisation increased P concentrations in shoot 1.6- folds, 3.2-folds, and 1.6-folds; and in root 1.9-folds, 1.9-folds, and 2.6-folds, respectively, in soybean, upland rice, and maize. However, it increased, decreased or were similar with other elements depended on elements and crop species. Applied mycorrhizal clearly contributed to enhance the growth and nutrient uptake of crop tested.

Abstract

Penelitian ini bertujuan untuk memahami perkecambahan benih srikaya terhadap Konsentrasi Indole Butyric Acid (IBA) dan lama perendaman. Penelitian ini dilaksanakan dari bulan Desember 2020 sampai Maret 2021 di Laboratorium Ilmu dan Teknologi Benih Fakultas Pertanian, Universitas Tadulako . Penelitian ini menggunakan rancangan acak lengkap (RAL) yang terdiri dari 2 faktor perlakuan, faktor pertama adalah konsentrasi IBA yaitu; A0 = Kontrol (tanpa IBA), A1 = 20 mg/l, A2 = 40 mg/l, A3 = 60 mg/l. Adapun faktor kedua lama perendaman benih dalam IBA yaitu P1 = 4 jam P2 = 8 jam, P3 = 12 jam. Hasil penelitian menunjukkan bahwa persentase kecepatan berkecambah benih, daya berkecambah benih, berat basah tanaman, dan berat kering tanaman srikaya pada berbagai konsentrasi IBA berpengaruh sangat nyata dibandingkan dengan kontrol yang tidak berbeda nyata. Sedangkan perlakuan lama perendaman tidak berpengaruh nyata terhadap kecepatan berkecambah, daya berkecambah, berat basah tanaman, dan berat kering tanaman.
