Abstract

The objective of this study is to investigate the form and application of reciprocity among corn farmers in Mantobua Village, Lohia Sub-district, Muna Regency. The informants were selected using the snowball sampling technique, and they were maize farmers who practiced reciprocity in maize cultivation in Mantobua Village. The data were collected through interviews, observations, and documentation using interview guides as instruments. The study employed the qualitative descriptive analysis method, which involves data reduction, data presentation, and conclusion drawing. The results indicate that farmers engage in comparable forms of reciprocity during corn farming activities, such as land clearing, planting, and harvesting. The social reciprocity relationships among corn farmers are increasing, as all farmers continue to engage in reciprocity activities. Reciprocity has been a long-standing practice that continues to this day. Younger farmers still uphold and apply the values of reciprocity to establish social relations between communities.

Abstract

Rice productivity in Inceptisols is often constrained by high phosphate fixation and low nutrient efficiency, despite high total nutrient reserves. This study aimed to evaluate the effectiveness of silicaenriched biochar in improving soil chemical properties and maintaining rice yield under reduced N, P, K fertilization. A field experiment was arranged in a Randomized Block Design with two factors: silicaenriched biochar (0, 1.25, and 2.5 t ha-1) and N, P, K fertilizer dosages (0, 50%, and 100% of the  recommended dose). Observed parameters included Cation Exchange Capacity (CEC), available phosphorus, total soil silica, and yield components. The results showed a significant interaction between treatments on soil chemical properties, particularly CEC and pH. Application of 2.5 t ha-1 silica-enriched biochar independently increased available phosphorus by 24.3% and total soil silica by 5.9% compared to the control, likely due to phosphate desorption mechanisms. Agronomically, while N, P, K fertilizer was the dominant factor for yield, the combination of 2.5 t ha-1  silica-enriched biochar  with 50% N, P, K dosage produced Milled Dry Grain (MDG) yields that were statistically comparable to the 100% N, P, K treatment. This indicated that silica-enriched biochar can substitute up to 50% of inorganic fertilizer requirements without compromised yield
