Abstract

The rain-fed rice fields of Jati Bali Village have contributed to increasing rice productivity in South Konawe Regency. This study aims to determine the status of soil fertility in rainfed paddy fields and to determine fertilization recommendations in rainfed lowland fields. This research was conducted in Jati Bali Village, West Ranomeeto District, South Konawe Regency and the Biology Laboratory of the Faculty of Mathematics and Natural Sciences, Halu Oleo University, taking place from May to July 2022. This research used a purposive sampling method based on different altitudes. Soil samples were taken, namely upper rice fields (65-71 m asl), middle rice fields (58-64 m asl) and lower rice fields (50-57 m asl) then carried out laboratory analysis on the soil samples. The results showed that the fertility status of rainfed lowland rice fields was classified as low and moderate. Low soil fertility is found in the upper paddy fields and middle paddy fields. While soil fertility is found in the lower paddy fields. Fertilizer recommendations for the upper paddy fields are 200 kg ha-1 of NPK fertilizer, 175 kg ha-1 of Urea fertilizer and 2 t ha-1 of manure. While the recommendation for fertilizer for middle and lower paddy fields is the application of NPK fertilizer as much as 150 kg ha-1, Urea fertilizer as much as 200 kg ha-1 and manure as much as 2 t ha-1.
