Response of phenological and agronomical attributes and thermal utilization efficiency of cotton cultivars to cumulative heat units under different sowing dates

The proper choosing crop cultivar keeps one of the most serious decisions for cotton farmers, since it determines the ceiling of the potential return, upon which the other agricultural activities, such as sowing dates, can be tailored. Accordingly, the current work deduce that sowing Super Giza 94 cultivar on 25-april is regarded as a promising practice for efficient use of prevailing climatic factors, hence balanced vegetative growth with high cotton productivity.
