| dc.description | Rhizobacteri indigenous Merapi yang telah dikarakterisasi sebagai isolat MA,
Mb dan MD tahan terhadap cekaman osmotik hingga > 2,75 M NaCl. Isolat MD
lebih kuat melarutkan Phosphat dibanding isolat MA dan MB, namun isolat MA
dan MB kemampuan Nitrifikasinya sangat kuat dan mampu Amonifikasi daripada
isolat MD. Isolat Rizhobakteri indegenous Merapi mampu berkembang di
rhizosfer tanaman padi dalam cekaman kekeringan, meskipun perlu adaptasi
hingga minggu ke 3 dan populasi campuran isolat MA-MB-MD tertinggi
(76,68x109 cfu/ml), namun dipengaruhi kadar lengasnya. Tanaman padi dalam
kondisi cekaman air (KL 40 %) nyata berpengaruh lebih baik terhadap semua
parameter pertumbuhan tanaman padi. Saling pengaruh antara perlakuan
campuran isolat MA-MB-MD dengan frekuensi penyiraman tampak pada
indikator pertumbuhan tanaman padi (akar dan tajuk), namun belum berpengaruh
sampai ke hasil padi. Frekuensi penyiraman 1 hari sekali tanpa inokulasi,
pengaruhnya sama dengan inokulasi isolat MB-MD penyiraman 3 hari sekali,
bahkan 6 hari sekali dengan inokulasi campuran isolat MA-MB-MD. Diharapkan
formulasi Rhizobacteri indigenous Merapi dapat digunakan sebagai pupuk hayati
untuk meningkatkan toleransi tanaman padi terhadap cekaman kekeringan | en_US |
| dc.description.abstract | Rhizobacteri indigenous Merapi Isolates have been characterization, and
MA, MB, and MD isolate could withstand osmotic stress up to >2.75 M NaCl.
MD isolate was stronger in dissolving Phospate than MA and MB isolate, but MA
and MB isolate had much stronger Nitrification capability and could perform
ammonification than MD isolate. Rhizobacteri indigenous Merapi could grow in
rice plant rhizosphere in drought stress, despite the need to adapt until the 3rd
week and highest mix of MA-MB-MD isolate (76.68x109 cfu/ml), although it
depends on the moisture degree. Rice plant in water stress (KL 40%) clearly
better influence against all rice plant growth parameter. There is reciprocal
influence between the mix of MA-MB-MD isolate treatment and watering
frequency which shows in rice plant growth indicator (root and crown), but still
no effect on rice product.. The effect of once per day watering without inoculation
was the same with MB-MD inoculation isolate with once per three days watering,
even with once per 6 days watering with MA-MB-MD mix isolate inoculation. It is
expected that the formulation of Rhizobacteri Indigenous Merapi could be utilized
as bio fertilizer to increase rice plant tolerance against the stress of drought. | en_US |
