A reduction in the amount of billet used in mechanized planting of sugarcane from the costs reduction prospecting is very important. This can be achieved by improving the metering system on billet planters. Several works presented by various researchers were reviewed and finally best plan selected for design, development and evaluation. The prototype was consisted of an endless chain conveyor with cupboards holding and conveying the billets to the surface of the planting furrows. The mechanism used to exclude extra billets was effective and at the same time simple in design and construction. Chain conveyor system enabled the timing of the billet travel to provide desired planting with overlap on without it. Mechanical Desktop software was used for technical modeling and drawing of plans. The fabricated prototype was evaluated on a laboratory test rig. An electric motor and reduction gearbox was used to supply the speed of the test rig conveying belt. The speed of metering system chain and test rig belt was controlled by an inverter. The metering system was evaluated based on the percent filling of the cupboards over–overlapping and under-overlapping as effected by planting speed (2.59, 3, 3.5, 4 km/h), cane vary (with and without debrie) and angle of the chain conveyor structure from vertical line(10, 15, 20 degree) with three replications. A factorial experiment in a completely randomized design was used to determine effect of speed of planting and angle of the chain conveyor on percent filling of cupboards, over-overlap and under-overlap indexes. Data obtained from experiments were analyzed using SAS and MSATAT_C statistical softwares. Results indicated that effect of the angle of chain conveyor according to vertical line; speed of planting and the interaction of all these independent variables on the percent filling of cupboards were significantly different. An increase in planting speed and angle of the chain conveyor decreased the percent filling of cupboards. No significant difference was observed for over-overlapping as a result of the experimental factors. Selection of the type of power train which omits slippage effect of the conveying belt may contribute to the results obtained for over-overlapping. Effect of the angle of chain conveyor and the interaction of the cane vary and speed of planting on under-overlapping was observed to be significantly different. For the best working condition, a planting speed of 4 km/h and with cane variety without debire and planting speed of 3.5 km/h with cane variety with debire give the best results as for as planting quality indices on concedes.
