تأثير الكثافات النباتية في نمو و حاصل و نوعية العلف الأخضر لصنفين من الذرة البيضاء (Sorghum bicolor (L.)‎ moench)‎

Abstract EN

A field experiment was performed during the autumn season of 2011 year in the (Abi Garaq) 10km west Hilla city.

To study the effects of two cultivars ( Engath ‘ Kaffer) and plant densities (13.3‘ 16.7‘22.2‘26.6‘33.3‘44.4) plant /m2 on some growth characteristics .

yield and Its quality .the experiment ‘was Applied by using split -plots according to (R.C.B.D) with three replicates.

Cultivars were assigned as a main-plots.

and plant densities as sub- plots.

The results indicated that using Engath cultivar significantly increased the growth properties Except plant height and crude protein .also significantly increased green forage yield (52.59) ta/ha .as well as the Cultivars was not significant in dry matter yield and crude fiber percent .significant incensement were attained by increasing plant density in plant height .

green forage yield .dry matter yield .crude protein percent and crude fiber percent .low plant density gave significant increasment in stem diameter and leaf area .as well as not significant in Ash percent total .plant density (44.4)plant/m- results maximum green forage yield (57.19)ta/ha.
