Table 3.
Effect of sowing time on iron (mg/Kg) and zinc (mg/Kg) contents in mature grains of drought-susceptible (PBW 343) and drought-tolerant (C 306) wheat genotypes grown under irrigated and rain-fed conditions. Values are mean ± standard deviation of three replicates; CD, critical difference; NS, not significant.
