Abstract
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.
