Efektivitas Berbagai Produk Fungi Mikoriza Arbuskula Dalam Meningkatkan Produktivitas Stylosanthes guianensis Pada Tanah Masam

Abstract

This study aimed to evaluate the effectiveness of Arbuscular Mycorrhizal Fungi (AMF) against Stylosanthes guianensis plants on acid soils. The research was conducted in the greenhouse of the Agrostology Laboratory of IPB. The research design used was a completely randomized design with 5 treatments and 8 replications, treatments were different types of AMF, without AMF (F0), commercial AMF (FU), AMF product IPB 1 (EM1), AMF product IPB 2 (EM2) and AMF product IPB 3 (EM3). AMF was given as much as 20 grams per planting hole. The given fertilizers were manure and NPK fertilizer. The treatment without AMF was given 100% of the recommended dose, while treatment with AMF was only given 50% of the dose. The results showed that there was no significant difference between treatments on growth variables (plant height, number of trifoliate leaves, number of branches, stem diameter and leaf chlorophyll). The type of AMF affected the fresh shoot production, and the highest was at EM1 (38.03 grams), as well as the number of root infections had a significant effect, and the highest production was at EM1 (77%). The conclusion in this study was that the use of AMF could reduce the use of manure and NPK 50% from the recommended dose, could increase the growth and productivity of Stylosanthes guianensis on acid soils and AMF product IPB 1(EM1) gave the best results.

Efektivitas Fungi Mikoriza Arbuskula yang Diproduksi dengan Teknik Fortifikasi Nutrisi Berbeda terhadap Produktivitas Stylosanthes guianensis pada Cekaman Kekeringan

“…Persiapan media tanam diawali dengan pengayakan tanah dan dilanjutkan dengan pengeringan tanah pada suhu ruang. Media tanam terdiri atas tanah kering sebanyak 5 kg per polybag, pupuk anorganik dicampur dengan pupuk dasar berupa pupuk organik (pupuk kotoran ayam) yang mengacu pada Purwanto et al (2014) dan pupuk anorganik yang mengacu pada Rizki et al (2022). Tanaman kontrol (F0) menggunakan dosis pupuk 100% yaitu 20 ton ha -1 pupuk organik, KCl 100 kg ha -1 , SP36 150 kg ha -1 dan urea 200 kg ha -1 .…”

“…Hasil ini didukung pernyataan Riliana, et al (2020) bahwa tanah yang tidak disterilisasi maka masih terdapat endogenous FMA alami. Rizki et al (2022) menyatakan pada kondisi masam, tanaman Stylosanthes guianensis yang diberi FMA produk Laboratorium Agrostologi IPB dihasilkan nilai kolonisasi FMA >60% dibandingkan dengan tanaman tanpa inokulasi FMA (<25%).…”

“…Lebih lanjut, FIPB1 sama baik dengan FU, yakni kualitas produk FIPB1 sama baik dengan produk FMA komersial (FU). Sejalan dengan hasil penelitianRizki et al (2022) bahwa FMA efektif bersimbiosis dengan baik pada tanaman Stylosanthes guianensis dan efektif meningkatkan adaptasi serta pertumbuhan tanaman pada tanah masam.…”
