Soybean is the rotation crop that dominantly grown after rice during dry season in most lowland paddy field of Eastern Indonesia. This field experiment aimed to improve dry season soybean production by spraying liquid fertilizer (LF) containing silicon. Burangrang soybean variety grown from August to October 2018 at Tenandon of Penujak Village, Praya Barat sub-distict of Central Lombok, West Nusa Tenggara Province. Five treatments were arranged on randomized block design with three replications on 100 m² plot size. The treatments were application of silicon-based liquid fertilizer (SLF) named SLF-ON, SLF-BX, SLF-BS, compared to non-silicon liquid fertilizer named LF-BU and the control which was without any liquid fertilizer (LF-0). Land preparation, planting, irrigation, and harvest was guided using integrated soybean management handbook. Yield and yield component data was collected at harvest. The result showed that application of LF was significantly increase total dry matter weight, including percentage dry matter accumulation on leaf, pods weight, and percentage of filled pods. Soybean production improved about 102.06%, 95.88%, 61.86%, dan 47.42% by spraying SLF-BS, LF-BU, SLF-ON, dan SLF-BX respectively when compared to LF-0.
