Influence of genotypes, spraying glutamic with potassium on the growth traits of the Hibiscus sabdarriffa L

The experiment was conducted in the summer season of 2023 in the Hawija Directorate / Kirkuk governorate to study the effect of genotypes ( black hit, red hit, Arab, Sudanese 3 ) and spraying with different concentrations of acid(zero and glutamic 250 mg bit+1, potassium element 600 mg bit+1 and glutamic 250 mg bit+1 +potassium 600 mg bit+1) in the growth, substance of the genotypes of randomization complete block design with three repetitions, each contains 16 experimental units, the area of each experimental unit is 2 * 2 m with a total of 48 experimental units, the results of statistical analysis showed significant differences in all studied traits.  The genotype of black hit exceeded most of the growth characteristics, including plant height (169) cm, number of branches (28.16) plant-1, leaf area (23061.04) cm2 leaf area and leaf directory (9.23) and chlorophyll a +b content in leaves (28.81) mg-1. The combination of glutamic 250 MML+1 +potassium element 600 MML+1 was significantly superior in all growth qualities, including the number of days from planting to 50% flowering (184.57%) days recipe number of days from planting to full maturity (214.86)days recipe plant height (180.66)CM recipe number of branches (29.54)branch leaf area recipe (23728.78)cm2 and leaf area guide recipe (9.48) cm2 Recipe sheet content of chlorophyll WA+B (22.49)mg-1. As for the interference of the genotype and the synthesis of clotamic acid and the potassium element, the combination of the genotype (hit black ) with clotamic acid and the potassium element (250+600mg per liter+1) exceeded in most of the characteristics of growth and genotype (arabib with the clotamic combination 250mg per liter+1 +potassium element 600mg per liter+1) in the character of chlorophylla content, the genotype (sudan3 with synthesis of glutamic 250mg per liter+1 +element potassium 600mg per liter+1) in the character of plant height.
