    abstract = {Dust is one of the limiting factors of solar thermal system in the agricultural sectors area. This paper presents the effect of dust on the performance of a solar dryer. Two similar solar dryers were constructed with the same dimensions and materials. One serves as control experiment, which was constantly cleaned up before each daily readings commenced; while the other served as the test dryer for the period of the experiment. The effect of dust on both the absorber temperature T<SUB>a </SUB>and the oven temperature T<SUB>o</SUB>, of each dryer was determined for the two experimental setups. The daily absorber temperature T<SUB>a </SUB>and the oven temperature T<SUB>o</SUB>, were recorded for a period of 25 days; for both dryers simultaneously. The daily maximum temperature of the absorber T<SUB>a </SUB>and the oven temperature T<SUB>o</SUB>, of each dryer were obtained. The results show that, the values of oven temperature of the control dryer are always higher and approximately constant in magnitudes between 42<SUP>o</SUP> C and 45<SUP>o</SUP> C compared with the oven temperature of the test dryer.  While the values of the absorber temperatures of the control dryer are between 55<SUP>o</SUP>and 65<SUP>o</SUP> C. The maximum temperatures of the absorber and the oven of the test dryer were observed to fluctuate in magnitude.}
