Abstract

AbstractThis study have been conducted in clay loam soil form Habbani-Ramadi district AL-Anbar province during the fall season of 2009 toinvestigate the effect of agricultural spaces among seed-bad(10,20&30cm)on th growth and yield properties for two sorghum genotypes (Inkath andRabeh).The expeniment system was split plot wih R.C.B.D design withthree replicates. The Rabeh cultivar had superiority in each of leaf eara andits index while the Inkath cultivar had superiority in dry weight yield andbiological yield in addition to its superiority in plant hight, grain yieldharvest index although its was insignificant in comparison with Rabehcultivar. The plant density in all of studied traits. The narrow spaces of(10cm) among plants had superiority in each of plant height, leaf areaindex, dry weight yield, biological yield and grains yield in comparison withlarge distance (30cm) plants which had superiority in each of leaf area andharvest index. The interaction between cultivars and spaces affectedsignificantiy in all of plant traits where the plants of Inkath with (10cm)agricultural spaces indicated the highest average for plant height(163.51cm) and grain yield (7.18 ton/ha). The plants of Rabeh cultivarwhich planted in 10and 30 cm spaces shows the highest average for leafarea (43.61cm2/plant) and its index (8.4) respectively .
