EFEKTIVITAS BERBAGAI FUNGI MIKORIZA ARBUSKULAR INDIGENUS TERHADAP SERAPAN HARA P DAN PERTUMBUHAN TANAMAN JARAK PAGAR (Jatropha curcas L.)

Abstract

Utilization of arbuscular mycorrhizae fungi (FMA) is an alternative way to improve soil fertility. Therefore, it must be developed by studying deeply the effectivity of the FMA. This is important due to either its ability to associate with almost all of vegetation family in terrestrial ecosystems or its ability to increase plant growth rate, seedlings quality, and crop yield, especially on critical land. A research about effectivity of variously indigenous arbuscular mycorrhizae fungi on P-sorption and Jatropha growth was conducted at laboratorium and glasshouse Agriculture Faculty, Andalas University. This research was aimed to gain the most effective isolate of arbuscular mycorrhizae fungi on growth of and P-sorption by Jatropha (Jatropha curcas L.) plant on critical land. Single isolat such as Glomus sp 2 , Acaulospora sp 1 , Gigaspora sp 1 , and compound isolate M7 (Glomus sp 2 ,+ Acaulospora sp 1 + Gigaspora sp 1 ) significantly affected plant height, canopy dry matter, infection percentage and intensity, and Psorption. M7 Compound isolate was the most effective innoculum. By this isolate, height of Jatropha seedlings was 27.5 cm, canopy dry matter 5.9 g, infection percentage 78.5%, infection intensity was 49.1, and P-sorption by canopy was 1.6 g for each seedling.

Effects of mycorrhiza and phosphate fertilizers on the growth and yield of foxtail millet (Setaria italica L.) under drought stress conditions

“…This is in accordance with Ginting et al (2018), stating that AMF had symbiotic relationship with plant roots and are obligate symbionts, so they require host plants to grow and develop. According to Muzakkir (2010), AMF can receive carbohydrates and growth factors from host plants as an energy source for growth and development, while plants can increase the uptake of P nutrients and other nutrients by the presence of root colonies with mycorrhizae.…”

Aplikasi Bokashi Eceng Gondok (Eichhornia crassipes) dan Fungi Mikoriza Arbuskula untuk Perbaikan Sifat Fisika Tanah Pasca Galian C dan Hasil Tanaman Cabai (Capsicum frustescens L.)

“…Ada pun tingkat ketergantungan tanaman terhadap FMA berbeda-beda. Muzakkir et al (2010) menyebutkan tingkat infeksi FMA pada akar tanaman bergantung pada kompatibilitas antara jamur dan tanaman. Menurut Jamilah et al (2016) Glomus dan Gigaspora mampu bersimbiosis dengan akar tanaman cabai.…”

The Response of Some Rubber Seedling (Hevea brasiliensis) Clones on Various Types of Indigenous Mycorrhizae in Ex-Coal Mined Soil Media

“…Type of plant gives a different response to mycorrhizae; soil type has closely related to pH and soil fertility. Each mycorrhizae has a difference ability and effectiveness to increase nutrient uptake and plant growth ( [11], [12], [13], [14], [15] and [16]). This experiment aims to get the best indigenous mycorrhizae for each type of rubber clone in the ex-coal mining media.…”
