Abstract: The cassava plant is a food crop and from year to year its needs are increasing but the productivity of the cassava plant nationally is still low. One of the efforts made to increase productivity is through fertilization and spacing. This study aims to determine the effect of Boron fertilizer treatment and planting distance on the productivity of cassava plants. There are 2 treatments in this study, namely Boron fertilization and planting distance, so there are 4 combinations of treatments, namely Boron fertilization with a planting distance of 1.4 m x 0.8 m, without Boron fertilization with a planting distance of 1.4 m x 0.8 m, Boron fertilization with a planting distance of 1.4 m x 1 m, without Boron fertilization with a planting distance of 1.4 m x 1 m. The results of this study of fertilizing Boron with a planting distance of 1.4 m x 0.8 showed the highest productivity of other treatments, namely 27,859 kg/ha. The starch content of cassava aged 11 months (at harvest time) in the treatment without Fertilization of Boron is higher than the treatment of Fertilizing Boron. These results show that the use of Boron fertilizer can increase the productivity of cassava, but it can reduce its starch levels.
