Abstract


"Science and Agricultural Production" provides a comprehensive
cover¬age of the factors of production underlying the Green Revolution,
and discusses in detail the constraints that inhibit their use and the
specific implications of such constraints for a social, economic and
ecological analysis for less developed countries. Ingrid Palmer
considers fertilizer usage to be the principal factor under¬lying the
Green Revolution. On the basis of a fitted rank correlation between
fertilizer usage and the yields of rice and wheat for various countries,
the author concludes that, given adequate soil moisture, agricultural
productivity can be greatly increased with improvements in the level of
fertilizer application alone, irrespective of the varieties grown. The
significance of the High Yielding Varieties (HYVs) begins to appear only
when the fertilizer application is about 10 times the present actual
dosage. Three characteristics of the HYVs, the leaf erectness, the high
tillering rate, and the leaf area, have been discussed as the chief
activators of nutrient uptake associated with a high conversion rate of
fertilizer to grain formation, through the process of
photosynthesis.
