Assessment of the suitability of pineapple waste as feedstock for vermicomposting CIGR Journal
Miito, Gilbert John; Komakech, Allan John; Zziwa, Ahamada; Kiggundu, Nicholas; Kambugu, Robert.
Declining soil fertility is a challenge to sustainable agricultural production in sub-Saharan Africa with a case of Uganda. However, the large volumes of agricultural waste generated from pineapples can be converted into soil conditioners through vermicomposting. by the use of earthworms. Several types of agricultural waste have been studied extensively as vermicompost feedstock, but little work exists on pineapple waste. The objective of this study was to investigate the suitability of pineapple waste for vermicomposting. To achieve this, an assessment of the physicochemical properties of fresh, pre-composted pineapple waste, and the resultant vermicompost, and determination of the optimal feeding rate and stocking density were performed.  The study...

Performance evaluation and optimization of the maize shelling operation of the multi-purpose farm vehicle CIGR Journal
Kabenge, Isa; Nsubuga, Denis; Zziwa, Ahamada; Kiggundu, Nicholas; Wanyama, Joshua; Banadda, Noble.
Small-scale farmers register high postharvest losses partly due to failure to carry out primary processing operations. Most of the maize shellers on the Ugandan market lead to high percentage of broken maize grains thus raising the risk of aflatoxin infection during storage. In this study, the operation of an existing maize sheller on the market with a shelling speed of 870 rpm for maize at 13 % moisture content was tested. The main objective of this study therefore was twofold; (i) to develop and evaluate a maize sheller and (ii) to optimize the multi-purpose vehicle shelling operation. The improved maize sheller was designed, fabricated, evaluated and optimized using a factorial experiment with shelling speed and moisture content as the main effects at...
