Root Interactions and Evaluation of Agroforestry and Intercropping Systems in Benin, West Africa
Author: Sigmund Johannes Lose
Publisher:
ISBN:
Category : Agroforestry
Languages : en
Pages : 260
Book Description
About the book In West Africa, traditional smallholder fallow systems urgently need sustainable intensification while maintaining soil fertility. Agroforestry systems were propagated to attain these targets. Earlier work, however, had not shown the expected positive effects on yield of the interplanted staple crops due to shading as well as root competition for nutrients and water. From 1995 until 1999, within the frame of the special research programme 308 (1985-1999) "Adapted farming in West Africa" of the University of Hohenheim, root studies were carried out in Southern Benin using the profile wall method for direct root observation and destructive soil monolith sampling. To estimate sustainability of the various treatments, i.e. fertilised, annual and perennial alley cropping in comparison to local practice, and production systems, i.e. maize-cassava intercropping, cassava sole-cropping as well as alley vs. block arrangement of perennial leguminous trees, yield trends were calculated for the three central trial sites at different edapho-climatical ecozones. Additionally, to quantify the complex interactions in agroforestry as well as in intercropping systems, data were used in system process modelling to give quantification of sustainable land management.

Innovations as Key to the Green Revolution in Africa
Author: Andre Bationo
Publisher: Springer Science & Business Media
ISBN: 904812543X
Category : Technology & Engineering
Languages : en
Pages : 1339
Book Description
Africa can achieve self sufficiency in food production through adoption of innovations in the agriculture sector. Numerous soil fertility and crop production technologies have been generated through research, however, wide adoption has been low. African farmers need better technologies, more sustainable practices, and fertilizers to improve and sustain their crop productivity and to prevent further degradation of agricultural lands. The agricultural sector also needs to be supported by functional institutions and policies that will be able to respond to emerging challenges of globalization and climate change.

Integrating New Technologies for Striga Control
Author: Gebisa Ejeta
Publisher: World Scientific
ISBN: 9812707085
Category : Science
Languages : en
Pages : 356
Book Description
Witchweeds (Striga species) decimate agriculture in much of Africa and parts of Asia, attacking the major cereal grains and legumes, and halving the already very low yields of subsistence farmers. Several years of research have provided promising technologies, based on the fundamental biology of the parasite?host associations, for dealing with this scourge. However, there is an apparent realization that these technologies will fail because highly successful weeds such as Striga evolve resistance to all types of controls unless proven methods are integrated with each other for a more sustainable solution.Integration is often an anathema to basic scientists who typically deal with single variables and solutions. However, key leaders in the development of the new knowledge-based control strategies, already in the field and under development, recently joined forces to develop strategies and projects in order to integrate the technologies in a symposium in Ethiopia in November 2006. The encouraging results are described in this peer-reviewed book, authored by leaders in the field who have been supplying the basic biology, genetics, biochemistry, and molecular information that have offered insights and generated technologies in how to deal with Striga.

Biotic Stress Resistance in Millets
Author: I. K. Das
Publisher: Academic Press
ISBN: 0128045809
Category : Technology & Engineering
Languages : en
Pages : 247
Book Description
Biotic Stress Resistance in Millets presents an important guide to the disease and pest-related challenges of this vital food crop. Biotic stresses are one of the major constraints for millet production, but newly emerging and forward-thinking problems with disease and insect pests are likely to increase as a result of changing weather, making this an imperative book on best practices. Current strategies are mainly through the development of resistant cultivars, as the use of chemicals is cost-prohibitive to many of those producing millet in developing countries where it is of most value as a food source. This book explores non-chemical focused options for improving plant resistance and protecting crop yield. This single-volume reference will be important for researchers, teachers and students in the disciplines of Agricultural Entomology, Plant protection, Resistance Plant Breeding and Biotechnological pest management. - Establishes basic concepts of host resistance providing foundational insight - Synthesizes past biotic stress resistance research with the latest findings to orient research for future strategies for plant protection - Focuses exclusively on host plant resistance on all major diseases and pests of millets - Presents data and strategies that are globally applicable as millets gain importance as a health food
