Pola Tanam Padi untuk Produktivitas Tinggi dan Indeks Pertanaman yang Optimal di Lahan Rawa Pasang Surut

Abstract

Optimalisasi penggunaan lahan rawa pasang surut untuk meningkatkan produktivitas dan hasil padi dapat dilakukan dengan peningkatan indeks pertanaman (IP). Penelitian ini dilakukan untuk mendapatkan informasi peluang peningkatan indeks pertanaman melalui penggunaan varietas unggul baru padi. Penelitian dilaksanakan pada Januari-Desember 2019 di Desa Sukaraja, Kabupaten Banyuasin, Sumatera Selatan dengan menguji tiga kombinasi pola tanam yang diulang empat kali. Perlakuan pola tanam yaitu: P1: Regas (musim tanam /MT 1)-Regas (MT 2); P2: Inpara 2 (MT 1)-Inpara 2 (MT 2); P3: Inpara 2 (MT 1)-Inpari 19 (MT 2)-Inpari 19 (MT 3). Regas adalah varietas lokal yang umum ditanam petani, Inpara 2 adalah varietas unggul baru (VUB) adaptif lahan rawa, dan Inpari 19 adalah VUB berumur genjah. Budidaya yang diterapkan yaitu Rawa Pasang Surut Intensif, Super, dan Aktual (RAISA). Pengamatan dilakukan terhadap karakter pertumbuhan dan hasil, serta perbandingan hasil antar pola tanam. Pola tanam padi-padi dengan VUB adaptif rawa (Inpara 2) merupakan pola tanam dengan hasil tertinggi sebesar 11.35 ton ha-1 GKG atau 34.6% lebih tinggi dibanding padi lokal. Indeks pertanaman di lahan rawa pasang surut berpeluang ditingkatkan menjadi tiga kali tanam pada kondisi curah hujan tahunan tinggi dengan didukung pendekatan varietas hasil tinggi dan umur pendek.

“…A form of incentive for farmers or agricultural wetland owners from additional annual land tax payments or Rural and Urban Land and Building Tax from non-agricultural property owners in Banjar Regency based on input from the Household Survey result provided in Table 8. The most recommended incentives for farmers and agricultural wetland owners are in the form of (1). cash compensation to landowners, namely 46.7%, then in the form of (2).…”

“…Tidal lands in South Kalimantan, which include freshwater swamps, peat swamps, and mangrove lands, have become the focus of productive agricultural development (Ansari et al, 2023). Using superior varieties in tidal swamp ecosystems in South Kalimantan has increased land productivity (Agustiani et al, 2022). Even though tidal land is included in the marginal category with various obstacles such as water fluctuations, salt intrusion, and nutrient deficiencies, the people of South Kalimantan still manage this land for agriculture and daily needs (Balad et al, 2021).…”
