This chapter describes the cultural method of insect pest control, which is affected by the manipulation of the environment in such a way as to render it unfavourable for the pest. This may be achieved through techniques such as crop rotation, hermetic storage systems, intercropping, manipulation...

This chapter compares factors explaining the inter- (interspecific) and intracrop (infraspecific diversity) of cereals grown by villages in Peasant Associations (PAs) of the northern Ethiopian highlands of Amhara and Tigray, building on the household-level analysis presented for the same sites in...

In this chapter, survey data are used to compare the determinants of intercrop (interspecific) and intracrop (intraspecific) cereal diversity on household farms in the highlands of northern Ethiopia using an approach based on a theoretic framework. Physical features of the farm, and household...

Some of the farm-level factors that are crucial for intensified food crop production in sub-Saharan Africa (SSA) is discussed. The current trends and indicators of intensification, including yield, total production per farm and consumption unit and sale of crops are also discussed, based on the...

Over the last 40 years several open-pollinated and hybrid maize varieties were developed for different agro-ecologies in Ethiopia. This study employed the economic surplus method for an ex-post evaluation of maize technology generation and transfer investment made in Ethiopia from 1986 to 2000. The ...

Mycotoxin contamination of food systems is a major problem in many countries in Eastern and Southern Africa. Most diets in the region are maize based, but cassava, sorghum, millet and peanuts also are important. These food systems are susceptible to aflatoxins, fumonisin B₁, zearalenone and...

This introductory chapter discusses the objective of the book, underlying research in the previous book and presents the summary and underlying research of each of the chapters of the current book. It also discusses the overall methodology used in gathering data for the study and the core finding...

In the past four decades, more than 40 improved maize varieties, including hybrids and open-pollinated varieties, have been developed and released in Ethiopia by the Ethiopian Institute of Agricultural Research in collaboration with the International Maize and Wheat Improvement Centre. Most...
