Abstract

The development of tidal land as agricultural land is one opportunity to meet food needs. The study aimed to determine the contribution of superior varieties in increasing tidal rice productivity in South Sumatra. The research was conducted in Banyuasin Regency in 2021 using survey and interview methods. The number of sub-districts where sampling was taken was 9 sub-districts which are representative of low tide land. The data collected in this research were the results of harvested dry grain (tiles), the varieties used, the type and dose of fertilizer used, planting methods and cropping index. Apart from primary, secondary data was also collected  as supporting data in the form of land area for each region and climatic conditions. The data taken was tabulated and analyzed  descriptively. The research results show that the productivity level of superior rice varieties is higher than the district average productivity. Increasing productivity by applying superior varieties reaches 1.5 t/ha.

Abstract

Optimalisasi lahan rawa lebak sebagai kawasan produksi padi berkelanjutan menghadapi tantangan biofisik yang kompleks, termasuk genangan musiman, keasaman tanah, dan keterbatasan infrastruktur teknis. Penelitian ini bertujuan untuk mengevaluasi penerapan mekanisasi pertanian tepat guna serta kapasitas petani dalam mengelola sistem pertanian di lahan rawa lebak Desa Arisan Musi Timur, Kabupaten Muara Enim. Menggunakan pendekatan deskriptif-kualitatif, data dikumpulkan melalui wawancara, observasi, dan dokumentasi terhadap petani, penyuluh, serta perangkat desa. Hasil menunjukkan bahwa alat seperti traktor roda dua dan pompa air portable memiliki efektivitas tinggi, sementara transplanter dan drum seeder kurang optimal akibat keterbatasan pelatihan dan ketidaksesuaian medan. Keberhasilan mekanisasi sangat ditentukan oleh kecocokan teknologi, pengelolaan air mikro, serta penguatan kelembagaan petani. Penelitian ini dilakukan pada tanggal 20 Oktober hingga 24 Oktober 2025, ketika lokasi penelitian tidak ada genangan limpasan air dari sungai Musi. Diperlukan kebijakan integratif yang mencakup perencanaan teknologi berbasis lahan, pelatihan operator, pengembangan layanan mekanisasi berbasis komunitas, dan kolaborasi lintas sektor. Studi ini merekomendasikan pengembangan sistem mekanisasi yang adaptif terhadap dinamika hidrologi dan sosial-ekonomi lokal sebagai strategi untuk meningkatkan produktivitas dan ketahanan pertanian rawa lebak secara berkelanjutan

Abstract

Irrigated rice fields serve as the primary land for rice production. Whether continuous rice cultivation or alternating with secondary crops, the cropping pattern in these filelds depends on water supply. These differences in cropping patterns will affect the soil's nutrient dynamics and rice productivity. This research aims to analyze the soil fertility dynamics and rice productivity in irrigated rice fields under different cropping patterns. The study used an oversite design with two factors, namely cropping patterns (rice-rice-rice (R-R-R), rice-rice-corn (R-R-C), and rice-rice-soybean (R-R-S)), and superior varieties (Inpari 23 and Mentik wangi). The results showed that the overall fertility of irrigated rice fields was low, with crucial limiting factors being deficiencies in total N, available P, and K nutrients. Differences in cropping patterns on Inceptisol significantly affect available P. The R-R-R cropping pattern, including the Inpari 23 and Mentik wangi varieties, provided the highest productivity, reaching 6.5-6.9 t ha-1. Selecting the right superior varieties and those by cropping patterns can increase the dry milled grain (MDG) yields by 23.52-30.1% compared to other superior varieties. Sufficient water availability throughout the growing phase can increase rice productivity by 33.3 -56.2% (1.5-2.3 times). Therefore, the key to intensive rice field management is not only to pay attention to soil fertility (nutrient dynamics), fertilization (organic and inorganic), and pest and disease control, but also to ensure the availability of sufficient water during cultivation and to use superior varieties. This research is beneficial for farmers, stakeholders, and the government in efforts to increase food security.
