Abstract: | Nanas merupakan salah satu komoditas ekspor andalan Indonesia yang
tumbuh baik di tanah masam. Tingginya penggunaan pupuk anorganik dalam
budidaya nanas mengakibatkan degradasi lingkungan. Kerusakan lingkungan dapat
dikurangi dengan menggunakan pupuk organik. Mikoriza merupakan agen hayati
yang dapat meningkatkan ketersediaan unsur hara P dan K di dalam tanah.
Penelitian ini bertujuan mengetahui efektivitas pupuk hayati mikoriza dan efeknya
pada pertumbuhan vegetatif tanaman nanas. Penelitian menggunakan rancangan
acak lengkap dengan sembilan taraf perlakuan terdiri dari P0 (Kontrol), P1 (NPK
100% - standar PT. GGP), P2 (Provibio 100% + NPK 100%), P3 (Provibio 100%
+ NPK 50%), P4 (Mikoriza 100% + NPK 100%), P5 (Mikoriza 100% + NPK 50%),
P6 (Provibio 100% + Mikoriza 100% + NPK 50%), P7 (Provibio 75% + Mikoriza
75% + NPK 50%), dan P8 (Provibio 50% + Mikoriza 50% + NPK 50%). Bibit yang
digunakan dalam penanaman adalah bagian crown. Polybag berisi 20 kg campuran
tanah dan kompos dengan rasio 9:1 digunakan untuk menanam bibit nanas pada
semua perlakuan. Dosis pupuk yang digunakan pada dosis 100% adalah NPK dalam
bentuk ZA 0,5 g, DAP 2 g, KCl 2 g, mikoriza 5 g, dan Provibio 10 ml / 1 liter air
per polybag. Setiap perlakuan memiliki 3 perulangan dan 5 sub anakan. Lokasi
penelitian berada di Terbanggi Besar, Kabupaten Lampung Tengah, Provinsi
Lampung. Parameter yang diamati adalah sifat kimia tanah, tinggi tanaman, jumlah
daun, biomasa, kolonisasi mikoriza, jumlah spora mikoriza, dan kesehatan akar
selama 4 bulan pada awal masa pertumbuhan vegetatif tanaman nanas. Analisis data
dilakukan dengan metode ANOVA dan Uji Lanjut DMRT. Sifat kimia tanah seperti
%C-organik, %N dan unsur hara tersedia meningkat setelah diberikan perlakuan
mikoriza. P8 memiliki hasil pertumbuhan vegetatif terbaik secara keseluruhan
dengan tinggi tanaman, jumlah daun, dan bobot basah tidak berbeda nyata dengan
P1 (NPK 100% - standar PT. GGP) dengan input pupuk anorganik lebih sedikit. P4
(Mikoriza 100% + NPK 100%) dipilih sebagai perlakuan mikoriza dengan
kolonisasi mikoriza terbaik karena mendapatkan persentase infeksi akar paling
tinggi pada 41,67% Pineapple is one of Indonesia's main export commodities, and it grows well in acidic soil. The high use of inorganic fertilizers causes environmental degradation. Environmental damage caused by inorganic fertilizers can be reduced by using organic fertilizers. Mycorrhiza is a biological agent that can increase the availability of P and K nutrients in soil. This study aimed to determine the effectiveness of mycorrhizal biofertilizers and their effects on the vegetative growth of pineapple plants. The study used a completely randomized design with nine treatment levels: P0 (Control), P1 (NPK 100% - PT GGP’s standard), P2 (Provibio 100% + NPK 100%), P3 (Provibio 100% + NPK 50%), P4 (Mycorrhiza 100% + NPK 100%), P5 (Mycorrhiza 100% + NPK 50%), P6 (Provibio 100% + Mycorrhiza 100% + NPK 50%), P7 (Provibio 75% + Mycorrhiza 75% + NPK 50%), and P8 (Provibio 50% + Mycorrhiza 50% + NPK 50%). Seedlings used are derived from crown’s part of pineapple. polybags containing 20 kg of soil and compost mixture with a ratio of 9:1 were used to plant the pineapple seedlings in all treatments. The ammount of fertilizer used at 100% dosage was NPK in the form of ZA 0.5 g, 2 g DAP, 2 g KCl, 5 g mycorrhiza, and 10 ml Provibio / 1 liter of water per polybag. Each treatment had three replicates and five sub samples. This research was conducted in Terbanggi Besar, Central Lampung Regency, Lampung Province. Parameters observed were soil chemical properties, plant height, number of leaves, biomass weight, mycorrhizal colonization, mycorrhizal spore count, and root health in 4 months after plant of pineapple’s early stage of vegetative growth. Data analysis was conducted using ANOVA and DMRT tests. Soil chemical properties, such as %C-organic, %N, and available nutrients, increased after mycorrhizal treatment. P8 (Provibio 50% + mycorrhiza 50% + NPK 50%) regarded as the best treatment for vegetative growth for achieving plant height, number of leaves, and wet weight comparable to that of P1 (NPK 100% - PT GGP’s standard) with less inorganic fertilizer input. P4 (Mycorrhiza 100% + NPK 100%) regarded as the best mycorrhizal treatment with the best mycorrhiza colonization for achieving the highest mycorrhiza root infection at 41,67%. |
