Comparison of the Effects of Different Sowing Methods on Yield and Yield Components of Some Newly released Bread Wheat Cultivars

This study was conducted during two consecutive growing seasons, 2023/2024 and 2024/2025 at Shandaweel Agricultural Research Station, Agricultural Research Center Egypt, to identify the most effective sowing methods for maximizing the productivity of newly released bread wheat cultivars. Four sowing methods, broadcast, drill, furrows and raising beds were evaluated alongside four bread wheat cultivars i.e. Sakha 95, Giza 171, Sids 15 and Misr 4. A split plot design with three replications was employed to assign the treatments. Sowing methods were allocated to the main plots and wheat cultivars were assigned to the sub-plots. The studied traits included: time to heading, days to physiological maturity, number of spikes m^-2, plant height, 1000-kernel weight, number of kernels spike^-1 and grain yield. Results indicated that the sowing methods had a significant or highly significant effect on all the examined characters in both seasons and their combined, except days to maturity in the 2^nd season, plant height and 1000-kernel weight in both seasons. Wheat varieties also, showed a significant or highly significant differences for all the studied traits across both seasons and their combined, except for 1000-kernel weight in the 2^nd season. The 1^st order of interactions effect were significant or highly significant in most cases. Raised beds proved to the most effective sowing method, producing the highest grain yield with a mean of 8.91 tons hectare^-1, among the cultivars, Sakha 95 performed best under raised beds achieving the highest grain yield with an average of 9.58 tons hectare^-1.
