Abstract

The growth and yield of two wheat cultivars (UPL W-1 and W-2) under low and high air temperature were evaluated. The test plants were exposed to low and high air temperature by planting in December and mid-February, respectively.

High air temperature significantly decreased plant height, hastened maturity and delayed booting and heading stage. Spike count/linear meter row and number of seeds/spike were significantly reduced by about 38 and 56%, respectively due to high air temperature. Similarly, there was a significant reduction in spike length, percent heavy seeds, 1000-seed weight and grain yield. The reduction in yield due to high air temperature was 79%.
