บทคัดย่อ (EN): Rubber is an important commodity in Indonesia since it is source of income for more than 12 million people and source of foreign exchange. Since 2011, there have been significant changes to he condition of rubber price, which also affected the income of smallholder. Some smallholders converted rubber plantations to other crops such as oil palm, coffee or annual crops such as maize and upland rice. In order to prevent more conversion of rubber to other crops, a technology is needed to increase the land productivity of rubber plantation. A technology that might be developed is the cultivation of rubber with wide row spacing (18 m x 2 m) x 2.5 m.Plant population of using this planting distance is 400 trees/ha. Using this wide spacing, smallholder could cultivate intercrops such as maize, paddy, cassava, etc. in area between rubber rows. The planting distance of maize as intercrop is 40 cm x 10 cm, while for paddy the planting distance is 75 cm x 20 cm, and the planting distance for cassava 100 cm x 100 cm. This technology has been developed in South Kalimantan and South Sumatra Province in the area of 700 ha and 400 ha, respectively. The oldest rubber plant was 100 months, however most of them are 12-36 months. Rubber clone used was PB 260. Survey conducted in 50 smallholdings and observation in the field, showed that the growth of rubber plant using this wide row spacing was good. The trees could be tapped at the age of 55 months. The average yield of rubber was 1500 kg/ha/year. The yield of hybrid maize in the third year has reached 5000 – 5500 kg/ha, upland rice of Dayang Rindu varieties could produce 2000 – 2250 kg/ha, peanuts 2000 – 2200 kg/ha, and cassava 16000 – 19000 kg/ha. Wide row spacing in rubber plantation has good prospect, because until third year, smallholders obtained yield from the intercrops, whereas the growth of rubber was normal.
