Farm resource management program. Annual report for 1989
1990
The work of the program in 1989 on the four major projects within the program namely: the management of soil; water and nutrients; agro-ecological characterization for resource management; and the adoption and impact of new technology and training and agrotechnology transfer is highlighted. An executive summary of research and training in 1988/89 season is given. Reports on the management of soil, water, and nutrients including a research conducted over the last four seasons covering on-farm evaluation of fertilizer use on barley, the on-farm assessment of improved chickpea production technology and the results from a large scale on-station trial assessing the productivity of contrasting wheat-based farming systems are presented. Reports on three contrasting aspects of ICARDA research on agro-ecological characterization illustrate how ICARDA's model for spatial weather generation can be used to identify response domains within which the probability of climatic events and their impact on technology performance can be identified, a characterization for the description of different farm types within relatively homogenous response domains in Jordan, and how long term climatic data sets and a wheat growth simulation model (CERES-N) can be used to assess the interaction of different levels of N-fertilizer use on soils of varying N-status and their impact on wheat production in Xian province of China is demonstrated. Reports concerned with the adoption and impact of technology, subjects covering the adoption of dynamics of winter chickpea in Morocco, an analysis of Syria's current strategy for feeding its expanding national sheep flock, an assessment of production functions descriptors of the impact of technology on barley production in Syria and Turkey are described. Studies on the impact of changing technology on agricultural labor in Algeria, Morocco, Tunisia, Jordan, and Turkey are summarized
