Abstract
A field experiment was carried out at district Rifai in Thi Qar governorate . The objective was to study the effect of sowing date on some of growth traits,green forage yield and dry matter yield of three sorghum cultivars Cafier,Irani and Super grazer with three planting date for fall season 2009. Results indicated that the planting date (15 July) gave the higher average for leaf area, leaf area index, plant higher, green forage yield and dry matter yield 5136.24 cm2 , 6.81 , 175.63 cm , 62.81 ton.ha-1 and19.09 ton.ha-1 , respectively .The results showed significant differences effect among the cultivars by effect the planting date , super grazer cultivar gave the higher average for leaf area , leaf area index , plant higher , green forage yield and dry matter yield 5133.40 cm2 , 6.80 cm , 175.77 cm , 64.13 ton.ha-1 and 19.94 ton.ha-1, respectively. Also the results indicated to superiority super grazer cultivar which was planting in(15 July) gave the higher average for leaf area , leaf area index , plant higher , green forage yield and dry matter yield 5697.72 cm2 ,7.64 , 187.90 cm , 66.90 ton.ha-1 and 21.2ton.ha-1 respectively.
