Abstract
SUMMARY The DTPA-extractable Zn in 28 Tarai soils was found to be significantly correlated with Bray's ‘percent yield’ values for rice and wheat. The critical limit of ‘available’ Zn, below which responses of both crops to applied Zn may be expected, was 0–53 mg Zn/kg soil. On the basis of this critical limit, it may be inferred that in the 16 Zn deficient soils, rice and wheat yields would respond markedly to zinc application. The magnitude of crop response in these soils was greater in rice (39–244%; mean value 117%) than in wheat (33–101%; mean value 60%).
