Abstract

Produksi tanaman tomat mempunyai kendala yang sering terjadi yaitu serangan penyakit layu Fusarium. Tujuan penelitian adalah mengetahui efektivitas dari jamur agensia hayati Trichoderma harzianum dan Gliocladium virens pada penyalutan benih tomat untuk pencegahan penyakit layu Fusarium. Penelitian dilaksanakan pada bulan Februari-Mei 2020 di Laboratorium Pengamatan Hama dan Penyakit Tanaman (LPHPT), Pandak, Bantul, DIY. Penelitian dilakukan menggunakan uji in vitro dan in vivo yang disusun menggunakan Rancangan Acak Lengkap (RAL) dengan 7 perlakuan dan 4 ulangan yaitu kontrol tanpa perlakuan, Fusarium, Trichoderma harzianum, Gliocladium virens, Fusarium + T.harzianum, Fusarium + G.virens dan kombinasi Fusarium +T.harzianum+ G.virens. Data dianalisis dengan menggunakan Analysis of Variance (ANOVA) pada taraf α=5% dan untuk mengetahui beda nyata antar perlakuan maka dilanjutkan uji Duncan’s Multiple Range Test (DMRT) taraf α=5%. Hasil penelitian menunjukkan perlakuan kombinasi T.harzianum+ G.virens efektif dalam menekan penyakit layu Fusarium. Uji in vitro menunjukkan bahwa Trichoderma harzianum, Gliocladium virens, atau kombinasi Fusarium +T.harzianum+ G.virens dapat menghambat pertumbuhan jamur F.oxysporum. Uji in vivo menunjukkan kombinasi T.harzianum+ G.virens menghasilkan indeks vigor, tinggi tanaman, jumlah daun, bobot segar akar, bobot kering akar nyata paling tinggi dan persen tanaman yang terserang layu Fusarium nyata paling rendah.

Abstract

Intercropping is an attempt from agriculture’s intensification program which purposes to obtain optimum yield and maintain soil’s fertility. This research aims to know whether intercropping systems have better crops and higher yields than monoculture systems. This research was conduct on May-August 2020 at Trengguno Kidul, Sidorejo, Ponjong, Gunung Kidul. The design of the experiment was arranged in a randomized block design (RBD) one factor and three blocks. One factor namely ST 1: soybean monoculture Dega variety, ST2: maize monoculture Dega 1 variety, ST 3: Maize monoculture Srikandi Ungu variety, ST 4: Intercropping system of soybean Dega 1variety with maize Pulut Uti 1 variety, ST 5: Intercropping system of soybean Dega 1 variety and maize Nasa 29 variety, ST 6: Intercropping system of soybean Dega 1 variety with maize Pulut Uri 1 variety, ST 7: Intercropping system of soybean Dega 1 variety and maize Srikandi Ungu variety. Data were analyzed statistically using SAS (Statistical Analysis System) ANOVA 5% and further tested with the Duncan test at a significant level of 5%. The results show soybean on monoculture system has better growth and yield than intercropping while on maize of Pulut Uri and Nasa 29 plant intercropping system has the same growth and yield than monoculture. Combination intercropping of maize variety namely Srikandi Ungu and Soybean variety namely Dega proved better growth and yield.
