Extract

Zinc deficiency is widespread in Indian soils (Kanwar & Randhawa, 1974). The critical limit of Zn varies for different soils and crops (Katyal, 1978). There is no information on the critical value of Zn in calcareous soils of Bihar for maize, a major food crop of this region, and the present study was planned to determine this so that responses to applied Zn could be predicted.
