Abstract

Pertambahan penduduk sejatinya harus juga dibarengi dengan pertambahan jumlah produksi untuk menjaga agar kebutuhan pangan masyarakat tetap terjaga. Penelitian ini dilaksanakan dengan maksud untuk mengevaluasi kesesuaian lahan serta menentukan alternatif perencanaan penggunaan lahan untuk pengembangan tanaman jagung, ubi kayu dan kacang tanah di Kecamatan Poleang Timur. Penelitian ini menggunakan metode survei bebas didasarkan pada unit lahan. Prosedur pelaksanaan survei tanah dilaksanakan dalam beberapa tahap meliputi tahap persiapan, tahap operasi lapangan dan tahap analisis sampel di laboratorium. Perencanaan penggunaan lahan dilakukan berdasarkan evaluasi kemampuan lahan dan besarnya bahaya erosi. Hasil penelitian menunjukkan bahwa pengembangan tanaman pangan di Kecamatan Poleang Timur Kabupaten Bombana sesuai untuk dikembangkan khususnya jagung seluas 5271,29 ha (78,04%), ubi kayu seluas 4872,34 ha (72,14%) dan kacang tanah seluas 5020,77 ha (74,33%). Alternatif arahan pengelolaan lahan untuk pengembangan tanaman pangan khususnya jagung, ubi kayu dan kacang tanah di Kecamatan Poleang Timur Kabupaten Bombana dilakukan pada tingkat sedang berupa pemupukan untuk faktor penghambat ketersediaan hara, penambahan bahan organik dan pengapuran untuk perbaikan faktor penghambat retensi hara, bahaya erosi diatasi dengan usaha konservasi tanah seperti penanaman sesuai kontur, pembuatan teras dan penanaman tanaman penutup tanah, pembuatan saluran irigasi/pengairan untuk penghambat ketersediaan air. Diharapkan dengan adanya penelitian ini mampu memberikan sumbangsih pemikiran dan sebagai bahan pertimbangan untuk pemerintah daerah setempat dalam hal penyusunan kebijakan serta untuk masyarakat dalam usaha pengembangan tanaman pangan.

Abstract

This study aims to examine the effectiveness of rhizobacteria in stimulating plant growth and acting as a biofertilizer that can enhance the viability and vigor of rice (Oryza sativa L.) seeds. The research was conducted at the Agronomy Unit Laboratory, Faculty of Agriculture, Halu Oleo University, from September to October 2024. The study was designed based on a randomized block design (RBD), consisting of 11 test isolates and 1 control. These isolates were tested for their effectiveness in improving the viability and vigor of rice (Oryza sativa L.). The test was carried out by soaking seeds in a rhizobacteria suspension, then germinating the seeds using a standard germination procedure. The observed variables included germination capacity, vigor index, seed uniformity, relative growth rate, and T50. The results showed that seed treatment with rhizobacteria significantly increased the viability and vigor of rice seeds (Oryza sativa L.), as seen in the variables of germination capacity, vigor index, T50, and relative growth rate. From this study, 2 isolates were selected that have the potential as growth promoters for rice seeds, namely DMW 4 and DSS 3. Further research is needed to test the effectiveness of these isolates in improving the growth and yield of rice (Oryza sativa L.) under field conditions.

Abstract

Drought is a climatic phenomenon that can significantly disrupt the growth and reduce the yield of rice plants. Inoculation of rhizobacteria can increase the yield of rice plants under drought stress conditions. The research was conducted at the Agrotechnology Laboratory of Agronomy Unit and Experimental Garden II of Faculty of Agriculture, Halu Oleo University, Kendari from October 2024 to January 2025. The treatments in this study were drought stress and rhizobacterial isolates. Drought stress treatment consisted of control (K0), 25% drought stress (K1), 50% drought stress (K2) and 75% drought stress (K3) while rhizobacterial treatment consisted of control (B0), isolate DMSJ 3 (B1) and isolate DSK 3 (B2). Each treatment was repeated 3 times, the treatment pots were arranged according to a split-plot design consisting of 5 polybags. Observational data were statistically analyzed using analysis of variance at the real level α 0.05 and will be further tested with DMRT α 0.05 if it shows a significant effect. The results showed that inoculation of rhizobacterial isolates DMSJ 3 and DSK 3 was able to increase plant yield under drought stress conditions characterized by an increase in the number of productive tillers, flag leaf area, flowering age, total grain per panicle, percentage of filled grain per panicle, 1000 grain weight, grain weight per panicle, yield and drought tolerance index. Isolates DMSJ 3 and DSK 3 have the same ability to increase yield and induce resistance of rice plants to drought stress conditions.
