| Abstract | ||||
| A Filed experiment was conducted in two consecutive seasons,2002/2003 and 200312004 at Gemmeiza Agricultural Research Station ,EL-Garbeia Governorate (Middle Delta),to study the effect of late sowing date on yield and yield components of five barley genotypes. Split Plot Design in three replications was used . Four sowing dates ( 1 st December .is" December,1 st January and 15th January) were arranged in the main plots. Five barley genotypes were arranged randomly in the sub-plots. Data were recorded for heading date, maturity date , plant height , spike length , number of spikes 1m2, number of grains Ispike , weight of kernels Ispike , grain yield, straw yield and biological yield. The results could be summarized as follows : sowing dates and genotypes treatments showed significant effect on grain , straw and biological yields as well as yield attributes for both seasons with some exception. The highest values of grain , straw and biological yields were recorded for the two sowing dates, Dec.1 and Dec.15. Delaying sowing date up to Jan.1 decreased grain yield on the average of the two seasons about (19 %) as compared with sowing date Dec.15 and about (34%)when Delaying sowing date up to Jan.15. Giza 128 recorded the highest values of plant height, weight of kernels Ispike ,while Giza 127 recorded highest values of number of spikes 1m2 and grain yield. | ||||
