Abstract
Abstract This study was carried out in Salah al-Din Governorate / Al-Dour (25 km from the governorate center) in one of the farmers’ fields during the season (2022-2023) with the aim of studying the effect of planting dates (the first date is 15/9, the second date is 1/10, the third date is 15/10, the fourth date 1/11, the fifth date 15/11) and symbolized by symbols (D1, D2, D3, D4, D5) and barley varieties (Arevat, Amal, Ebaa 99, Buraq, Shuaa, Rehan, Sameer) and symbolized by symbols(V1, V2, V3, V4, V5, V6, V7) in the growth characteristics and fodder productivity of the barley crop, and the experiment was applied using Complete randomized block design according to the arrangement of the split panels with three replicates, where dates were placed in the main panels and items in the secondary panels. The test results appeared Planting D5 was superior in number of branch, green fodder yield, and dry weight of stems with values reaching 540.089 branch. m 2 , 8.5481 tons ha -1 , and 312.197 gm. m 2 respectively, While D1 achieved the highest value for the crop growth rate, amounting to 0.001923 g m -2 day -1 , while D4 gave the highest average weight of dry leaves, 274.7476 gm. m2., We did not obtain any significant differences between planting dates and the absolute growth rate of the crop. The varieties differed significantly, as the V7 variety succeeded in the desired direction for the characteristics of number of branch 451.938, absolute growth rate 0.0206 gm.day -1 , green fodder yield 7.4150 tons ha -1 , dry weight of leaves 298.498 gm. m 2 While the V5 variety excelled in terms of crop growth rate by 0.00241 g m -2 day -1 , while in the dry weight of leaves, the V7 and V5 excelled with the highest averages of 326.356 and 319.262 gm. m 2 . As for the interactions, the combinations of D5*V7 achieved the highest values for the number of branches and the dry weight of the stems, with values reaching 582.53 branch. m 2 and 353.6 gm. m 2 , As for the crop growth rate, the highest combination of interaction at date 1 and variety 5 was 0.004375 g m -2 day -1 , In the absolute growth rate, the highest combination at the first D1 and V7 was 0.027443 gm.day -1 , The combination of D5*V5 gave the highest average green fodder yield of 10.95 tons ha -1 , While the overlap of date 4 with variety 7 achieved the highest dry weight of leaves, 309.47786 gm. m 2 .
