Abstract:\u00a0<\/strong><\/span><\/p>\n

In 2018, the research was conducted at the farm of the University of Ibb’s Faculty of Agriculture and Food Sciences. The investigation included nitrogen fertilizer concentrations of 0, 140, 280, 420, and 560N kg\/ha. The investigation was conducted using a completely randomized block design with three replications. Except for the concentration of 420N kg\/ha, the concentration of 560 N kg\/ha produced the greatest number of secondary stems\/plant, plant height (cm), and number of leaves\/plant.The differences between them were insignificant. Fertilization had no significant effect on the number of main stems, as the study revealed that the concentration of 420N kg\/ha gave the highest values and a significant advantage over all other treatments for the ratio of the number and weight of large tubers, plant production\/kg, average tuber weight\/kg, and total productivity ton\/ha. They were 71.93, 82.13, 69.98, 1.67, 0.20, 68.16respectively, whereas the treatment with 420N kg\/ha registered the lowest values for the number and weight of small and medium tubers, with a significant decrease compared to the other fertilization rates. On the other hand, utilizing the same nitrogen fertilizer rate of 420N kg\/ha led to a significant increase in the number of tubers in the plant compared to the control and the higher concentration, resulting in the highest yield of 68.16N kg\/ha.<\/span>
