Abstract

Increasing paddy consumption can be done through efforts to increase yields by improving production technology, one of which is using organic nano silica fertilizer. Food biofortification efforts in paddy are also considered a solution for improving nutrition to help improve community nutrition. This research aims to determine the colour cultivar and dosage of nano silica organic fertilizer and the interaction between the two, which provide high growth and production and determine the nutritional quality of functional paddy. Functional paddy planting occurred in Manakku Village, Labakkang District, Pangkep Regency, South Sulawesi, from May to August 2023. The research was arranged in a separate plot design with the main plot varying doses (kg ha-1) of nano silica organic fertilizer consisting of control (d0), 500 (d1), 1000 (d2), and 1500 (d3), as well as subplots of four cultivars of red rice (Oryza sativa L.), namely Inpari 24 (v1), Pamelen (v2), Pamera (v3) and Inpago 7 (v4) as well as one cultivar of black rice Jeliteng (v5). The results were that the interaction of 1000 kg ha-1 organic nano silica fertilizer and red rice 'Inpago 7' (d2v4) provides the best yield of 5.62 t ha-1. Characters that have a significant positive correlation with yield are plant height (0.64**), number of productive tiller (0.74**), grain total (0.54*), and weight of 1000 grains (0.88**). The quality of functional rice based on glycaemic index (GI) analysis showed that the black rice 'Jeliteng' with a dose of organic nano silica fertilizer of 1000 kg ha-1 (58.9%) had the lowest GI value.
