New Crop Varieties: Impact on Diversification and Stability of Yields

Mohammad Alauddin () and Clement Tisdell

Chapter 11 in The ‘Green Revolution’ and Economic Development, 1991, pp 227-245 from Palgrave Macmillan

Abstract: Abstract In the preceding chapters, and in earlier publications, we have isolated increased multiple cropping (Alauddin and Tisdell, 1986c) and increased control over agricultural micro-environments due to greater use of HYV-associated techniques (Alauddin and Tisdell, 1988d) as significant factors contributing to reduced relative variability of crop yields with the adoption of HYVs. However, we have not given in-depth attention to the possibility that a contributor to this result may be increased crop diversification, especially greater diversity in varieties of the same crop. In this chapter we extend our earlier results by concentrating on the diversification aspect.
