Model development and optimisation of the disc plough efficiency on loamy-sand soil in South-East Nigeria

This study was conducted to model and optimise the efficiency of a disc plough on loamy-sand soil in South-East Nigeria aid farmers examine choose right ploughing implement based type for an effective bountiful production. The operational speed cutting depth were taken as factors efficiency. results revealed that highest field 80% noted when worked at 30 cm 5 km·h–1 while lowest 68.10% achieved 9 10 cm. quadratic significant response (P < 0.05). indicated coefficient determination (R2) 0.98, which specified high correlation among factors. predicted R²Â (0.76) consistent with adjusted 0.96. adequacy precision 24.89 showed suitable indicator could navigate design space. optimum desirability 77.50% 1.00 were, respectively, obtained 7 Farmers can, however, assess select implements developed model.
