Abstract

The demand for raw corn materials for the food industry in Indonesia, which reached around 1.2 million tons in 2021, can only be fulfilled by a domestic supply of 7,000 tons. In 2022, it is anticipated that the demand for corn in the food industry will rise to between 1.5-1.6 million tons. Corn production can be increased by employing technological advancements and using immature coconut plantation land. One of the strategies to extend the corn planting field is to cultivate corn on expanding coconut plantations. The development of planting corn on plantation land as a high-potential intercrop, particularly in immature coconut areas, is carried out to improve the nation's deficient corn production. The decision and implementation of coconut replanting have significant potential for corn production. Three-year-old immature coconut plants can be used to cultivate corn. The development of corn plants in coconut plantations continues to increase. The area of coconut plantations in Asahan Regency rose from 22,293.11 ha in 2020 to 23,260.86 ha in 2021. Therefore, the cultivation of corn in the coconut plantation field might meet the Ministry of Agriculture's estimated corn requirement of 1,6 million tons. The findings show that Intercropping corn with coconuts increases yields by 80 % to monoculture corn. In addition, corn demands can be supported by efforts to cultivate corn in coconut plantation areas using shade-tolerant corn VUB technology, enhancing soil fertility by restoration, organic fertilizers, and NPK fertilizer.
