3.2.3. Effect of Heat Stress on Yield of the Wheat Plant

In the case of heat stress, the crop yield was 3623.47 kg ha−1, while in control, it was 10270 kg ha−<sup>1</sup> (Table 1). In other words, the crop yield was reduced by 75% after heat stress application. This was further related to the 1000-grain weight, which was reduced significantly (*p* ≤ 0.05) from 56 g in control to 21.50 g once the stress was applied. The heat stress was significantly (*p* ≤ 0.05) more deadly for the plant than salt and waterlogging stress, as shown in Table 1.
