Abstract

Peningkatan produktifitas kacang kayu sebagai pengganti kedelai dapat dilakukan dengan mengaplikasikan mikoriza. Penelitian ini bertujuan untuk mengetahui jenis mikoriza dari Desa Cabbiya, Pulau Poteran, Sumenep Madura, jumlah inokulan mikoriza yang efektif sebagai biofertilizer, serta biomassa tanaman kacang kayu setelah diinokulasikan dengan mikoriza. Identifikasi dilakukan hingga tingkat genus berdasar karakter morfologi (bentuk, warna, ornamen) menggunakan buku “Working with Mycorrhizas in Forestry and Agriculture” serta website INVAM. Parameter pertumbuhan utama adalah biomassa, sedangkan parameter pendukung ialah persen infeksi akar, masing-masing pada perlakuan kontrol negatif, kontrol positif, inokulum mikoriza asal desa Cabbiya 25 g, 50 g, 75 g, dan 100 g. Hasil biomassa dianalisis menggunakan Anova dengan taraf kepercayaan 90% dan dilanjutkan dengan uji Tukey. Dari hasil identifikasi ditemukan genus Glomus, Gigaspora, Acaulospora, dan Scutellospora. Nilai biomassa terendah 0,1809 g pada perlakuan kontrol negatif (tanpa mikoriza) dan terbesar 0,4542 g pada pemberian inokulum mikoriza 100 g. Jumlah inokulum mikoriza yang efektif sebagai biofertilizer mencapai ± 3200 spora/100 g tanah. ============================================================================================================= Increasing pigeon pea’s productivity as a substitute of soybeans require mycorrhiza as biofertilizer needed. This research aims to know type of mycorrhiza from Cabbiya Village, Poteran Island, Sumenep Madura, number of inoculum mychorriza which effective to be biofertilizer, also biomass of pigeon pea after being inoculated with mycorrhiza. Identification is done up to the genus level based on morphological characters (shapes, colours, and ornament) using “Working with Mycorrhizas in Forestry and Agriculture” guide book, also firmed by website of INVAM. The main growth parameter is biomass, then supporting parameter used is percentage of root infection, each on control negative, control positive, 25 g, 50 g, 75 g, and 100 g inoculum mychorriza from Cabbiya village. Biomass data result was analyzed using Anova suited at 90% confidence level and continued by Tukey test. There were genus of Glomus, Gigaspora, Acaulospora, and Scutellospora based on identification results. The lowest biomass was 0,1809 g on control negative (without mycorrhiza) treatment, and the highest was 0,4542 g on 100 g of inoculun mycorrhiza treatment. Inoculum mycorrhiza which effective to be biofertilizer reached ± 3200 spore/100 g of soil.
