GENETIC POTENTIALITY OF SOME BREAD WHEAT GENOTYPES UNDER LOW INPUT CONDITIONS IN NEW LAND
AHMED MOHAMED AHMED GADALLA;
Abstract
The present investigation was carried out during
200212003 and 200312004 growmg seasons at Nubaria Agriculture Research Station, Agricultural Research Center, at Nmth Tahrir under calcareous soil and smface inigation.
The main objectives of this investigation were to evaluated some different bread wheat genotypes for high yielding ability under nmmal and low input systems and selecting some wheat genotypes to be adapted to low nitrogen fe1tilizer levels and water stress conditions and to study the use efficiency of applied nitrogen and nitrogen uptake response to N fertilizer under low input system.
The experimental design was split-split plot, the irrigation treatments were allocated to the main plot, nitrogen fertilizer levels to the sub-plot and bread wheat genotypes to the sub-sub plot. The inigation treatments were two, three and five inigations, the nih•ogen fe1tilizer was applied at rates of 72, 144 and 216 Kg Nlha and bread wheat genotypes were eight genotypes.
The data were recorded on number of spikes 1m2, number of kemels I spike, 1 000-kemel weight, grain yield (t/ha), sh•aw yield (tlha), biological yield (t/ha), harvest index, total nih•ogen uptake, nitrogen use efficiency, nih•ogen utilization efficiency, and nih•ogen uptake efficiency. The data were subjected to proper statistical analysis of variance according to Snedecor and Coc!U"an ( 1967) and the combined analysis was conducted according to Cochran and Cox (1957).
