Pengaruh Jenis Fungi Mikoriza Arbuscular Terhadap Pertumbuhan dan Hasil Tanaman Tomat (Lycopersicum esculentum Mill)

Abstract

ABSTRAK: Penelitian ini bertujuan untuk mengetahui pengaruh jenis fungi mikoriza terhadap pertumbuhan dan hasil tanaman tomat. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) non faktorial dengan 3 ulangan.  Adapun faktor yang diteliti yaitu faktor jenis mikoriza, yang terdiri atas 4 taraf yaitu: Tanpa Mikoriza, Mikoriza Glomus sp,  Mikoriza Gigaspora sp, Campuran Mikoriza Glomus sp  dan Gigaspora sp. Parameter yang diteliti yaitu serapan hara N dan P, bobot berangkasan (segar dan kering) fase vegetatif dan generatif, biomassa akar (segar dan kering) fase vegetatif dan generatif, potensi hasil per tanaman, panjang akar fase vegetatif dan generatif, dan tingkat infeksi mikoriza (%). Hasil penelitian ini menunjukkan bahwa Jenis fungi mikoriza berpengaruh sangat nyata terhadap bobot berangkasan segar fase vegetatif, bobot akar segar fase vegetatif, bobot berangkasan kering fase vegetatif, bobot akar kering fase vegetatif dan panjang akar fase vegetatif serta berpengaruh nyata terhadap serapan hara N. Jenis fungi mikoriza yang terbaik untuk pertumbuhan dan hasil tanaman tomat adalah Gigaspora sp.

Effect of Fungi Arbuscular Mycorhiza on the Growth and Yield of Tomato Plants (Lycopersicum esculentum Mill)

ABSTRACT: This aimed of this experiment to study the effect of mycorrhizal fungi on the growth and yield of tomato plants. This study uses a randomized block design  non factorial with three replications. The factors studied were kind of mycorrhizal, which consists of four levels ie: Without Mycorrhiza, Mycorrhiza Glomus sp, Mycorrhiza Gigaspora sp, Mixed Mycorrhizae Glomus sp and Gigaspora sp. The parameters studied were uptake of N  and P,  fresh and dry weight of biomass on phases of vegetative and generative, fresh and dry weight of root biomass on phases of vegetative and generative, the potential yield per plant, the length of root on vegetative and generative phase, and infection rate mycorrhizal. The results of this study showed that the type of mycorrhiza fungi very significant effect on the weight of fresh biomass vegetative phase, the vegetative phase fresh root weight, dry weight biomass vegetative phase, dry root weight and root length of the vegetative phase of the vegetative phase and significantly affect the nutrient uptake N. type of fungi mycorrhiza is best for growth and yield on tomatoesis to Gigaspora sp.
