This document contains summaries of multiple research projects related to cacao production, processing, and utilization in Region 02. The projects investigate topics like propagating cacao seedlings in different soil media, using various sizes of polybags, utilizing cacao pod husks as feed for broilers, benchmarking socioeconomic factors of cacao farmers, integrating nutrient management to increase yields, comparing monoculture and agroforestry production systems, determining spatial nutrient variability and yield correlations, enhancing pollinator habitats, conducting varietal trials, comparing growth in different agroecosystems, analyzing effects of fermentation and roasting on flavor, sensory evaluation of homemade chocolates with varying cacao nibs, and improving the nutritive value

8. Benchmark Studies
on Cacao
Production in
Region 02
Objectives
To determine the socio-
economic status of cacao
farmers in terms of age,
gender, highest educational
attainment, occupation, civil
status, monthly income,
household size, total number
of children, type of land and
total land area.
To find out the causes of
low yield of cacao
production in Region 02.

9. Integrated
Nutrient
Management for
Increase Cacao
Productivity
Objective
To determine the
appropriate kind and rate
of inorganic fertilizer
applied singly or in
combination with
organic fertilizers and
other soil amendments
to increase cacao
production.

12. Biodiversity in the
Cacao
Agroecosystem:
Nutrient and Pest
Management
Objective
To compare the
economic and ecological
factors to be considered
when producing cacao in
either a monoculture or
agroforestry system.

13. Site-Specific
Nutrient
Management on
Cacao
Objective
To determine the
nutrient spatial
variability within
individual fields and to
correlate this nutrient
variability with yield
variability
