The chapters of this book describe the physiological, population, and community ecology of weeds within agroecosystems, with the goal of recognizing details relevant for better weed management. Recognition of the germination, establishment, growth, and reproduction requirements of different weeds will allow identification of life stages that are particularly susceptible to attack. Recognition of the effects of different tillage and crop rotation systems will be present in a particular field at a particular point in time. Recognition of how crops, insects, and pathogens affect weed performance through resource competition, allelopathy, herbivory, and disease will suggest better ways to use these phenomena in integrated approaches to weed management. Recognition of how and when weeds affect crop performance through resource competition, allelopathy, and positive and negative interactions with crop insect and disease pests will provide insights into when and how thoroughly weed management tactics should be imposed.}, keywords = {agricultural ecology, agricultural systems, biological control, ecology, integrated control, tillage, weeds}, isbn = {0-8493-6816-2}, url = {http://www.worldcat.org/oclc/16682275}, editor = {Miguel A.

The project dealt with an arid zone where grain is produced in association nitrogen fixing trees. The multiple benefits of this association make it unlikely that farmers will change this production system unless major climatic or infrastructural changes occur. The probable persistence of this pattern has major implications for agricultural research strategies.}, keywords = {agricultural systems, agroforestry, research , social sciences}, isbn = {0-8133-7136-8}, url = {http://www.worldcat.org/oclc/13009091}, author = {Barry H Michie}, editor = {Jeffrey R Jones and Ben J.

During the rest or fallow periods intervening between crops, the natural fertility of the soil is restored for renewed utilization in a subsequent period of crop growth. This traditional system of cultivation is in ecological balance with the environment and does not irreversibly degrade the soil resource, provided a sufficient length of fallow is allowed for soil restoration.}, keywords = {agricultural systems, agroecology, agroforestry, alley cropping, appropriate technology and intermediate technology, climate, farming systems, horticulture, livestock, rainfall, research , shifting cultivation, soil management, watersheds}, isbn = {92-5-102121-X}, url = {http://www.worldcat.org/oclc/11418879}, author = {Food and Agriculture Organization of the United Nations (FAO).
