Popis: Aim of study: To develop a kenaf harvesting technology, that will improve kenaf production efficiency. This study evaluated the effect of some operation parameters on the performance of a tractor-mounted kenaf (Hibiscus cannabinus L.) harvester. Area of study: The experiment was performed at the Teaching and Research Farm of the Obafemi Awolowo University, Ile Ife, Nigeria. Material and methods: The experiment was initiated after 10 weeks of planting kenaf on the experimental field. The experimental design was a 3 × 4 × 5 experiment evaluating the effect of kenaf maturity (average stem diameter at week after planting (WAP) 10, 12, 14 and 16), kenaf varieties (‘Cuba 108’, ‘Ifeken 400’ and ‘Ifeken Di 400’) and forward speed of the tractor (2, 3.5, 5, 6.5 and 7.7 km/h) on effective field capacity, field efficiency, and operational loses of the machine. Main results: The effective field capacity of the machine decreased with increase in plant maturity and increased with increase in forward speed of the machine. The optimal value of the effective field capacity was 2.13 ha/day, when harvesting ‘Ifeken 400’, at crop maturity of 10 WAP, and forward speed was 5 km/h. The field efficiency of the machine was found to decrease with increase in crop maturity and forward speed of the machine. The field efficiency of the machine was 97%, with ‘Ifeken 400’ crop maturity of 10 WAP and forward speed of 2 km/h. Research highlights: The crop maturity, kenaf variety and forward speed of tractor have effect on the effective field capacity, field efficiency and the operational loss of the tractor-mounted kenaf harvester
