Background and Objective: The effort of lowland rice need to be supported by the program integration of lowland rice with oil palm plants to food self-sufficiency. The research was aimed to obtain the vegetative, physiological and yield components of several varieties of lowland rice with specific plant spacing in integrated mature-4 by smallholder of oil palm. Materials and Methods: The research used the split-plot design with the main-plot is the plant spacing (J1 = 25×20 cm, J2 = 25 ×25 cm, J3 = 25×30 cm and J4 = 25×35 cm) and sub-plots is the rice varieties (V1 = Inpara 2, V2 = Inpari 4, V3 = Inpari 10 and V4 = Inpari Sidenuk). Parameters were analyzed by ANOVA and the means effect was followed by DMRT at a level of 5%. Results: The Inpari Sidenuk variety significantly increased the highest grain yield plot–1 and yield ha–1 of 0.42 kg and 3.36 ton, respectively compared to other varieties. The plant spacing of 25×25 cm (J2), 25×30 cm (J3) and 25×35 cm (J4) can significantly increase the fresh weight stover/clump of 13.53, 13.29 and 13.22 g, respectively. In overall, plant spacing of 25×25 cm can increase the panicle length, number of grain/panicle, percentage of filled grain, 1000 grains weight, grain yield plot–1 and yield ha–1 compared to other plant spacing. Conclusion: The use of Inpari Sidenuk variety with the plant spacing of 25×25 cm has the potential to be recommended in integration with mature-4 of smallholder oil palm to increasing yield and food self-sufficiency.
