英文文献：Packages of Practices; A Step at a Time with Clusters?
英文文献作者：Mann, Charles K.
英文文献摘要：
Despite increased use of modem technology, few Turkish wheat farmers have adopted the complete recommended package of practices. Reconsidering the package as clusters of practices adopted in an agronomically and economically logical sequence provides a better explanation of farmer behavior and a guide for useful agronomic experimentation and economic analysis.
