Abstract

Unsur hara fosfat kedua setelah nitrogen dan unsur hara makro yang penting bagi pertumbuhan serta perkembangan tanaman. Penelitian ini bertujuan untuk mengisolasi dan mengidentifikasi jumlah dan keragaman bakteri pelarut fosfat dari rhizosfer tanah tanaman aren, serta menguji kemampuannya dalam melarutkan fosfat. Penelitian ini adalah jenis penelitian deskriptif kualitatif. Analisis yang dilakukan menggunakan deskriptif meliputi karakteristik makroskopis dan mikroskopis serta uji indeks bakteri pelarut fosfat (BPF). Nilai indeks pelarutan fosfat diukur dengan membandingkan total diameter koloni dan zona bening holozon diameter koloni pada media Pikovskaya agar. Hasil penelitian ini menunjukkan jumlah bakteri pelarut fosfat tertinggi diperoleh pada lokasi 2 lapisan 1 dengan nilai 57,5 x 10-8 CFU/ml dan terendah diperoleh lokasi 2 lapisan 2 dengan nilai 40,5 x 10-8 CFU/ml. Hasil karakterisasi secara morfologi menunjukkan hasil yang cukup beragam. Sedangkan uji kemampuan melarutkan fosfat yang tertinggi ditemukan lokasi 2 lapisan 2 dengan nilai indeks 3,75. Dimana memiliki potensi yang cukup tinggi sehingga, dapat diperlukan pengujian lebih lanjut.

Abstract

Vesicular Arbuscular Mycorrhizae and Trichoderma sp are biological agents of microorganisms to assist in nutrient uptake, suppress pathogen populations, accelerate growth and increase crop yields. This research aimed to determine the effect of age transplanting seeds with the application of Mycorrhizal Arbuscula Vesicular and a dose of Trichoderma sp., which could increase the production of Purple Corn (Zea mays var Ceratina Kulesh). This research was carried out in an experiment using Split Plot Design. The Main Plot was the age of transplanting (m) with the application of Vesicular Arbuscular Mycorrhizae as much as 10 g.tan-1, which were: m1 (transplanting age 0 days), m2 (transplanting age 7 days), m3 (age of transplanting 10 days). The Sub-Plot (SP) was The Trichoderma sp. (t), which were: t0 (without Trichoderma sp.), t1 (Trichoderma sp. 100 g.tan-1), t2 (Trichoderma sp. 200 g.tan-1). Each treatment in the main plot and sub-plot was combined to create nine treatment combinations. Each treatment combination was repeated three times so that a total of 27 plot units. The results showed that the treatment of  10 days of transplanting with the application of Mycorrhizal Vesicular Arbuscula as much as 10 g.tan-1 gave the best results on cob diameter and Phosphorus uptake. Dosage of Trichoderma sp. 200 g.tan-1 gave the best results on planting crown weight, cob diameter, The combination of 10 days of transplanting, while the application of Vesicular Arbuscular Mycorrhizae and a dose of Trichoderma sp. 200 g.tan-1 gave the best results on cob weight per plant, Nitrogen and Potassium uptake.
