Development and Performance Evaluation of Maize Stalk Harvester

A power operated maize stalk harvester was designed and developed in the Dept. of Farm Machinery Power Engineering, MPUAT, Udaipur, Rajasthan during 2018-19. The objective this study is to optimize operational parameters harvesting by using RSM techniques. effects independent i.e., blade speed (2000, 4000 6000 rpm) moisture content (38, 42 46%) on cutting efficiency (%) fuel consumption (l/h) were studied. To correlate with dependent parameters, central composite rotatable design (CCRD) method a quadratic model used. findings indicated that variations affected (l/h). assess statistical significance model, an analysis variance (ANOVA) performed, which showed good agreement between experimental data predicted model. rpm 46.0% found be optimum for 96.52% 0.72 l/h consumption.
