Abstract :
A field experiment was conducted in 2011 – 2012 at the experimental field of the Department of field crop,Faculty of Agriculture university of Babylon in Abugray, Iraq (latitude 32 31- N, lonqitude of 44, 21- E in silty clay soil).
Completely randomized block design in a split block with three replications .
The results were as follows : The 100kg N.ha-1 gave a highest mean for plant height , flag leaf area and its dry weight , spike dry weight at anthesis , no. of spikes . there was no significant differences with the treatment 150 kg N.ha-1.
150 kg N.ha-1 gave highest mean for no.of tillers , grain yield, Raised – bed and Ridge gave a highest mean of plant height , flag leaf area , flag leaf dry weight , spike dry weight at anthesis and grain yield.
Ridge pattern gave a highest mean of number of tiller , no.of spikes there were no significant differences with raised – bed , there were a significant interaction between planting methods and nitrogen level exept flag leaf area . |
