Mixed cropping system is reported to increase chili pepper productivity by
suppressing insect and pathogen developments. Participatory plant breeding might produce
desired variety and combination of hybrid varieties. The superior model for mixed cropping
for chili pepper variety, insect and disease resistances is designed as preferred by
consumers. Results showed that the best mixed cropping for chili pepper hybrids was
UNIB CH13 and Dwiguna UNIB. This combination produced total fruit weight of 300.12
g per-plant, longest fruit length of 13.66 cm, fruit stalk of 5.43 cm, canopy area of 3172.53
cm2, biggest stem diameter of 11.79 mm and highest fruit weight of 5117.22 g per-plot.
Mixed cropping of UNIB CH13 and Dwiguna UNIB had the lowest disease incidence
caused by Cercospora sp. Infested by Colletotrichum, Fusarium and Begomovirus on chili
peppers plants were not significantly different. Although growers prefered to select
monocropping of UNIB CH13 and Dwiguna UNIB, but growers chose the combination of
UNIB CH13 and Dwiguna UNIB for fruit shape and homogeneity.
