EFFECT OF ORGANIC FERTILIZER AND BREAD WHEAT (Triticum aesitivum L.) GENOTYPES ON YIELD AND YIELD COMPONENTS
Abstract
The experiment was carried out at College of Agricultural Engineering Sciences farm, Duhok
University, the experiment was laid out in Randomize Complete Block Design with three replications and
arranged in factorial experiment to evaluate the effect of organic fertilization levels and bread wheat
genotypes (Tamoz-2, IPA-95 and Abu. Garib-3), and the foliar organic mineral fertilizer used at three
rates 0.5, 0.75 and one litter.
The results showed highly significant effect of bread wheat genotypes in all studied characters with
exception of weight grain spike -1
, also organic fertilizer exhibited significant effect in plant height, leaf
area, 1000-grain weight, number of grain spike, length of spike and grain yield, while the effect of
interaction between genotypes and organic fertilizer levels showed highly significant effect for all
characters except of spike length, the results indicated that the rate 1 liter and Abu. Garib-3 gave the
maximum plant height, leaf area, 1000 grain weight, number of grain spike-1
, weight of grain spike-1
, spike
length and grain weight with values (91.2, 56.9, 47.5, 48.7, 2.8, 8.7 and 355.0 gm) respectively.
The correlation coefficient of grain yields gave highly significant with plant height (0.972), leaf area
(0.916), 1000 grain weight (0.923), number of grain spike-1
(0.951) and spike length (0.974).
The results for this study had shown that, using organic fertilizer and suitable wheat genotypes effects
significantly on yield and most of yield components.
