Upcoming increase in global warming is potential threat to crop production, which necessitates determining responses of crops to cope with this ever-increasing adversary. This study focused on the responses of two differentially heat tolerant maize (Zea mays L.) varieties Sadaf (heat tolerant) and Agatti-2002 (heat sensitive) to glasshouse condition at three growth stages across spring and autumn seasons (by keeping the plants inside the glass canopies). Results revealed that growth and yield responses of maize varieties were quite differential across the seasons and treatments, which was evident from the interactions of varieties and treatment present in one season and disappeared in the other. Among the growth attributes, silking and grain filling stages during spring season were more sensitive to glasshouse effect as most the interactions of varieties and treatments were evident for various growth attributes.
