WHEAT RESPONSE TO SOWING METHODS AND NITROGEN FERTILIZER LEVELS
Two field experiments were conducted at the Exp. Sta., Fac. of Agric., Mansoura Univ., during 200412005 and 200512006 seasons to determine the effect of
\ three sowing methods (broadcasting, drilling in rows and hilling in ridges) and five nitrogen fertilizer levels (50, 65, 80, 95 and 110 kg N/fed) on growth, yield and its components and quality of wheat cv. Sakha 93. A split plot design with three replications was used. The most important results could be summarized as follows:
1- Sowing methods had a significant effect on most of the studied characters in the two seasons. Drilling in rows 15 cm apart produced the highest values of all studied characters in both seasons followed by sowing wheat grains on both sides of ridges in hills 15 cm apart. Whereas, the lowest values of all studied characters resulted from broadcasting method.
2- Nitrogen fertilizer levels significantly affected all studied characters in both seasons. All studied characters gradually increased by increasing nitrogen fertilizer levels from 50 up to 110 kg N/fed in both seasons. The highest values of studied characters resulted from fertilizing wheat plants by 110 kg N/fed in both seasons. But. the differences between 80 and 95 kg N/fed and 95 and 110 kg N/fed were not significant in most of the studied characters in both seasons.
3- The interaction between sowing methods and nitrogen fertilizer levels had a significant effect only on number of spikes/m2 and grain yield in both seasons.
4- Generally, to maximize wheat productivity and reducing production costs as well as environmental pollution it is recommended sow wheat by drilling methods or hilling on both sides of ridges of former cotton or maize and fertilizing with 80 - 95 kg N/fed. Whereas, reducing nitrogen fertilizer levels from 110 to 80 kg N/fad did not associated with significant difference in grain yield, which was 0.27 ardab/fed only (as an average of both seasons) with monetary value about 40 L.E., whereas the price of nitrogen amount reduced (30 kg N/fed) reached to 70 L.E.
