Description Phosphorus (P) deficiency is common in sorghum-grbwing
regions of the semi-arid tropics (SAT) (Sallanpaa, 1982). and
ranks second in importance only after nitrogen (N) deficiency. In
addition to the deficiencies of these two nutrients, other nutrient
disorders may be common. For example, zinc (Zn) deficiency is
common in India. pqi~sium (K) and sulphur (S) deficiency in
West Africa, and 'alhinum (A]) toxicity in Latin America
(SBnchez and Salinas, 1981). Amelioration of P deficiency by
application of P fertilizers is costly. Thus, improved farming
practices have the best chance of adoption by the small subsistence
farmers with limited financial resources if they involve only
moderate amounts of low-cost inputs. To achieve this, we need to
determine efficient fertilizer practices in conjunction with the
development of P-efficient cultivars.
