Abstract:
The sorghum variety (Ezraa 7) was used to study the simple correlation and regression between some important traits and grain yield in sorghum, to find out the most studied traits that are related and contributed to yield, so that it helps the researcher to select them in order to obtain the best yield under the influence of different levels of irrigation and fertilization Potassium and sprayed with zinc .The experiment was carried out at Salhab village in Al-Ghab area – Hama governorate during the agricultural season 2020 according Split- Split Design with three replications, where irrigation dates were distributed to the main plots (7,14,21 days) in addition to the control treatment (14 days), while the secondary plots included potassium fertilization rates (60,80,100 kg/ha). And spraying with zinc (0.4, 0.8, 1.2 kg / h). The results indicated that productivity ton/ha was strongly and significantly positively associated with the trait of grain weight per plant (r=0.865**) and moderately positive with the two traits of harvest index and protein percentage (r=0.328**, r=0.470**), respectively. Also, the correlation of the regression coefficient was positive and strong with the characteristics of the weight of the grains in the plant, the harvest index, the weight of 100 grains and the percentage of protein in the grains and thus it can, and thus can be adopted, these characteristics as electoral criteria to improve the productivity of sorghum under the conditions of cultivation and the studied treatments of irrigation, potash fertilization and spraying with zinc.
