الملخص EN

A field experiment was conducted in the fields of Agricultural College University of Baghdad during fall season 2007 and spring season 2008 .

This was to study the effect of row spacing ( 5 , 10 ,15 and 20 cm) to different genotypes of Sudangrass , two sorghum cultivars (Rabeh and Inkath) and two hybrids (Money Maker and High Grazer), using factorial experiment within randomized complete block design .The hybrids Money Maker and High Grazer produced highest forage yield 40,19 , 39.15 , 37.12 and 37.44 tons/ha.

in both fall and spring seasons , respectively.

Highest forage yield (40.19 34.90 ton/ha) was produced from using 15 cm between rows in fall and spring seasons, respectively .

Significant differences were found between genotypes and row spacing in flowering dates , plant height , number of leaves/plant and leaf area.

Plants of the Hybrid High Grazer using 20 cm row spacing produced highest leaf area (4948 and 4445 ) cm3 , respectively .

It was recommended to use hybrids (sudangrass x sorghum) Money Maker and High Grazer using 15 cm between rows to produce higher forage yield.
