Effect of Experimental Unit Border on Yield and Yield Components in Bread Wheat Experiments

This investigation was carried out at Sids and Sakha Agricultural Research Station, Agricultural Research center (ARC.), Egypt, during the two successive growing seasons 2018/2019 and 2019/2020. The objective of this research was to assess the border effect in wheat cultivation for yield and yield components. The measurements were realized on border and inner rows in 12 bread wheat cultivars. The results indicated highly significant effects for treatments (Border and inner rows), cultivars and their interaction, the border rows treatment is higher than the inner rows treatment. For grain yield, the best cultivar was Misr 1 (0.315 Kg m-1) under the border rows. For number of spikes m-1, Sids 13 gave the highest value (103.67 spikes m-1) in the border rows while the cultivar Sids 12 gave the highest value (73.35 spikes m-1) under inner rows treatment. Regarding number of kernels per spike, the best cultivar is Sids 1 under both treatments (border and inner rows). Concerning the trait of 1000-kernel weight, Gemmiza 11 recorded the highest value for 1000-Kernel weight under both treatments border and inner rows stand treatments.
