استجابة الحنطة (.Triticum aestivum L)‎ للسماد النيتروجيني بتأثير طريقة الزراعة

Abstract EN

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 .
