Integrated crop management of hot pepper (Capsicum spp.) in tropical lowlands

Research output: Thesisexternal PhD, WU


Hot pepper ( Capsicum spp.) is the most important low elevation vegetable commodity in Indonesia. Yields are low, in part due to crop health problems. Farmers' practices were surveyed by means of exploratory surveys. Hot pepper pests and diseases were identified and described. Components of integrated crop management (ICM) of hot pepper were investigated, such as plant raising practices during the nursery phase, and mulching and nitrogen fertilizing during the field phase. Experiments were carried out in the field at various locations in Indonesia and Malaysia and in growth chambers and greenhouses in the Netherlands. During the nursery phase, screen-covered nurseries protected plants from aphids and aphid-transmitted viruses. In the field phase, after transplanting, potted transplants showed better crop establishment than bare-root transplants and earlier harvesting. When plantlets were raised in screen-covered nurseries, a plant raising period of 1½ months appeared best for plant growth and earliness of harvesting after transplanting. In the field phase, white and silvery plastic mulches improved plant growth and earliness of fruiting, reduced virus infection and thrips injury, and improved crop production. Nitrogen fertilizing improved plant growth. Increasing nitrogen application rates aggravated anthracnose fruit rot and Cercospora leaf spot. Best yields were attained with nitrogen fertilization of 150 kg N/ha. The investigated components of ICM benefited crop production through, among others, improvement of crop health. The effects of the ICM components on yield were irrespective of cultivar or location.
