Abstract
Soil exhaustion and nutrient depletion are major constraints to pineapple farming in Uganda. This study explored
potential for using on-farm waste from pineapple farming to conserve soil fertility and enhance agricultural productivity. Data
collection was done using key informant interviews, focus group discussions, and a semi structured survey questionnaire
administered to 109 randomly selected pineapple farmers and processors. The data was analyzed in SPSS to generate
descriptive statistics for selected variables followed by cross tabulation to explore linkages between the variables. Results
indicate that farmers engaged in pineapple farming, have diverse socioeconomic backgrounds but activities engaged in are not
significantly associated with socioeconomic variables examined except farming experience and gender. The major challenges
faced by the farmers included soil exhaustion, lack of appropriate technologies, inappropriate pineapple waste management and
decline in yield. It was noted that strategies used by farmers employing use of on-farm waste have not yielded significant
contribution and as such farmers resort to use of off-farm manure which is expensive and increasingly hard to secure. It was
recommended that a sustainable technology harnessing the abundant but underutilized on-farm biomass waste be developed to
produce a highly nutrient-rich soil conditioner to enhance pineapple yield and as such empower the farmers.
