摘要:Pupuk hayati mikoriza dapat mempertahankan produktivitas lahan dan ramah lingkungan. Penelitian ini bertujuan menganalisis pengaruh pemberian pupuk hayati mikoriza terhadap pertumbuhan bawang merah (Allium cepa var. aggregatum) serta mengetahui infeksi akar, dan pengaruhnya terhadap kadar N, P, K tanah. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap (RAL). Perlakuan pengujian pupuk hayati yang dilakukan berdasarkan Peraturan Menteri Pertanian No. 70/ Permentan/ SR. 140/10/2011, terdiri dari 6 perlakuan (A-F) sebagai berikut: A) kontrol, B) pupuk standar, C) pupuk hayati mikoriza, D) pupuk hayati mikoriza + 25% pupuk standar, E) pupuk hayati mikoriza + 50% pupuk standar, F) pupuk hayati mikoriza + 75% pupuk standar. Terdapat 5 ulangan sehingga diperoleh 30 satuan percobaan. Pupuk hayati mikoriza dapat mengurangi kebutuhan pupuk standar (PS) menjadi 25% sampai 50%. Kombinasi pupuk hayati 2.5 g/tanaman dengan 50% PS menghasilkan tinggi tanaman dan bobot biomassa terbaik, namun secara ekonomis lebih direkomendasikan pemakaian 25% PS. Perlakuan yang diaplikasikan mikoriza memiliki nilai infeksi akar yang sangat tinggi yaitu diatas 75%. Jenis spora yang berhasil berasosiasi adalah Acaulospora sp., Glomus etunicatum, dan Glomus sp. Pengaplikasian mikoriza menghasilkan respons peningkatan sebesar 14.91% pada P-tersedia Latosol, sedangkan terhadap K-dd dan N-total tidak berpengaruh nyata.
其他摘要:Mycorrhizal bio-fertilizers can maintain land productivity and are environmentally friendly. This study aims to analyze the effect of mycorrhizal biofertilizer on the growth of shallots (Allium cepa var. Aggregatum) and to determine root infection and its effect on soil N, P, K levels. The experimental design used was a completely randomized design (CRD). The treatment of biological fertilizer testing is carried out based on the Regulation of the Minister of Agriculture No. 70 / Permentan / SR. 140/10/2011, consisting of 6 treatments (AF) as follows: A) control, B) standard fertilizers, C) mycorrhizal biological fertilizers, D) mycorrhizal biological fertilizers + 25% standard fertilizers, E) mycorrhizal biological fertilizers + 50% standard fertilizer, F) mycorrhizal biological fertilizer + 75% standard fertilizer. There were 5 replications so that 30 experimental units were obtained. Mycorrhizal bio-fertilizers can reduce the need for standard fertilizers (PS) to 25% to 50%. The combination of biological fertilizer of 2.5 g / plant with 50% PS produces the best plant height and biomass weight, but economically it is recommended to use 25% PS. The treatment applied to mycorrhizae had a very high root infection value, which was above 75%. The types of spores that were successfully associated were Acaulospora sp., Glomus etunicatum, and Glomus sp. The application of mycorrhizae resulted in an increased response of 14.91% for P-available Latosol, while for K-dd and N-total there was no significant effect.
