Tidal Rice Yield Assessment in Central Kalimantan, Indonesia, under Different Cultural Practices

Abstract

This research aimed to assess the performance of a technology package in relation to rice yield in a B-type tidal rice field in Central Kalimantan province (Indonesia). We selected four areas with different hydrological conditions, soil characteristics, and farmer management systems in Pulangpisau and Kapuas Regency. The introduced technology package covered water management, soil tillage, amelioration and fertilization, adaptive high-yielding varieties, and crop protection. The results showed that, on average, the rice yield of Terusan Karya was 5.52 t ha−1, followed by Belanti B (3.75 t ha−1), Belanti A (3.61 t ha−1), and Talio Hulu (3.27 t ha−1). Rice varieties that yielded more than 5 t ha−1 were Inpara 8 (6.28 t ha−1), Suppadi 89 (5.54 t ha−1), Inpara 3 (5.46 t ha−1), and Inpara 2 (5.36 t ha−1). The implementation of a site-specific technology package combined with intensive guidance for the farmer on its implementation is the key factor in increasing rice productivity in tidal rice farming.
