The experimental work was carried out through agricultural summer season of 2014 at the experimental farm of Gemmiza Research Station, Gharbiya governorate to minimize energy and costs in weeding and fertilizing processes for fiber crops (Kenaf and Roselle) in small farms. The manufactured multipurpose unit performance was studied as a function of change in machine forward speed (2.2, 2.8, 3.4 and 4 Km/h) fertilizing rates (30,45 and 60 Kg.N.fed-1),and constant soil moisture content was 20%(d.b) in average. Performance of the manufactured machine was evaluated in terms of fuel consumption, power and energy requirements, effective field capacity, theoretical field capacity, field efficiency, and operational costs as a machine measurements .The experiment results reveled that the manufactured machine decreased energy and increased effective field capacity and efficiency under the following conditions: -machine forward speed 2.2Kmlh. -moisture content average 20%.
