Effect of preventing irrigation during flowering and grain filling stages on phenological and yield characteristics of some Egyptain maize cultivers [electronic resource].

Includes references.

Effect of preventing irrigation during flowering and post- flowering stages on some phenological and yield characteristics of five Egyptian maize (Zea mays L.) cultivars was studied during 1999 and 2000 seasons at the Agric. Res. Stat., Fac. of Agric, Cairo Univ , .Giza, Egypt. Preventing irrigation at flowering (PIF) and grain filling (pIG) stages did not produce significant changes in number of days to 50% tasseling. Preventing irrigation at flowering caused significant elongation in the whole period from planting to physiological maturity, while preventing irrigation at post -flowering stage significantly decreased grain filling and whole growth periods. Water stress at flowering stage (pIF) caused significant reductions in all yield traits, except 100 - kernel weight which showed insignificant decrease, and barren stalks which exhibited significant increase as compared to full irrigation (F1) treatment.
