Abstract
The research aim to determinee the proper NPK dose and application frequency of silica fertilizer to seed production of IPB 3S rice. The research was carried on June — September 2017 in Pinrang, South Sulawesi. A Randomyzed Completely Block Design with nine levels (75% dose + once silica application, 75% dose + twice silica application, 75% dose + thrice silica application, 100% dose + once silica application, 100% dose + twice silica application)/ (300kg NPK ha-1+ 150kg Urea ha-1 + twice silica application), 100% dose + thrice silica application, 125% dose + once silica application, 125% dose + twice silica application, and 125% dose + thrice silica application.
