dc.description.abstractThe effects of maximum temperature, rainfall and growing degree day on grain yield of durum wheat (Triticum durum Desf.) were studied during the period of available years (2005-2017) in the study sites. A polynomial equation was described the relationship between grain yield, maximum temperature and rainfall for four growing stages of winter wheat. The nonlinear relationships were used from time-series variations in temperatures, rainfall and yields. The maximum positive effects of rainfall (R2=0.72*) on grain yield was in the mid-season stage (heading, anthesis and grain filling) of the crop. However, there was a negative effect of temperature more than 30°C on grain yield. The highest negative effects (R2=0.31 through 0.86*) of maximum temperatures were in the crop development stages (vernalization and tillering). The yield might decrease about 2.5% for every 1°C increase in the growth period based on the daily mean temperature of 12.4°C for all the study locations. The critical maximum temperatures on threshold values declining yield and positive effects of rainfall on grain yield varied according to the altitudes and longitudes. © 2022, National Agricultural Research and Development Institute.
