Chapter 4 (Page no: 46)

Farmer perceptions of the biophysical constraints to rice production in sub-Saharan Africa, and potential impact of research.

This chapter describes farmer perceptions of major biotic (weeds, diseases, insects, birds and rodents) and abiotic (drought, flooding, extreme temperatures, and soil-related constraints, such as non-fertile soil, low organic matter content, poor waterholding capacity, nutrient deficiency, Fe toxicity, salinity, alkalinity, acidity and erosion) constraints that limit and reduce rice yields in farmerś fields in sub-Saharan Africa. The potential impact of research addressing such constraints is discussed.
