Agricultural Machinery & Mechanization



​Book description

​The dynamic nature of agricultural operations and the complexity of agricultural machinery are indices of scientific research diversity as evident in the wide spread requirements in agricultural operations and sustainable productivity.

Engr. Segun presents extensive works on mechanization of agricultural operations and machinery utilization in agricultural production as documented in this eleven-chapter book to acquaint students and researchers with the principles of agricultural machinery and provide them with requisite knowledge and skills in various agricultural machinery required for effective ​mechanization.
