Effect of Planting Date on Phenology, Productivity and Flour Quality of Some Wheat Cultivars.

Abstract

A field experiment was conducted to determine the effect of two planting dates ; early (25 th Oct.) and late (15 th Dec.) in addition to the control planted at 20 th Nov. on phenology, growth, yield (yield components and yield quality) of four bread wheat (Triticum aestivum L.) cultivars ; Sakha 93, Sakha 94 ,Gemmeiza 9 and Giza 168 at Sakha Agricultural Research Station. In general, the obtained data showed that, the requirement of days and Growing degree days (GDD) to attain different phenological stages (seedling, booting, heading, anthesis and maturity) decreased with delay in sowing date. Also, planting on the control date (20 th Nov.) surpassed the other sowing dates in all yield studied parameters and flour quality. However , late sowing date (15 th Dec.) caused an increase in most technological properties (protein , wet and dry gluten) of the yielded grains .

“…Late planted wheat crops have less number of growing days, hence grain yield is negatively affected. In other sense, such crop has increased exposure to the high temperatures (Farooq et al, 2013;Haroun et al, 2012;Mostafa et al, 2009). Similarly, it has earlier been established that a delay of one day from the optimal wheat sowing yielded in a decline of 1% of grain yield (Ihsan et al, 2016).…”
