Structural suitability of 10-year old Pinus caribaea timber with a forest fire history in farm buildings CIGR Journal
ZZIWA, AHAMADA; MUKASA, JOSEPH; KIZITO, SIMON.
Forest fires in Pine and Eucalyptus plantations are common in Uganda especially in the dry periods. In an event of fire gutting a nearly mature plantation, tree farmers usually try to reduce losses by extracting and lumbering the residual trees for use in agricultural buildings. However, there is no empirical data to guide material selection based on strength and structural integrity of the timbers from burnt plantations. Therefore, this study investigated the effect of fires on selected physical and strength properties of timber extracted from a 10-year old stand of Pinus caribaea that had been burnt. Test specimens were prepared and tested for MOE, MOR and compression parallel to the grain using a Testometric AX M500 – 25KN Universal Testing Machine in...

Potential for Use of Pineapple Waste to Enhance Soil Fertility on Smallholder Organic Farming in Kayunga District, Uganda CIGR Journal
ZZIWA, AHAMADA; Kambugu, Robert; Komakech, Allan John; Kiggundu, Nicholas; Miito, Gilbert; Kyazze, Florence.
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 analysed 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...
