Effect of Different Nitrogen and Potassium Fertilization Levels on Vegetative Characteristics of Carrot
Keywords:
Carrot, nitrogen, potassium, vegetative characteristicsAbstract
Two field experiments were conducted in a sandy soil at Al-Kufra City, Libya, during the two successive winter seasons of 2021and 2022, to study the effects of varying nitrogen and potassium fertilization levels, as well as their interaction, on vegetative characteristics of carrot. Data cleared that that nitrogen fertilizer levels treatments have significant effect on vegetative characteristics i.e., plant height, plant weight, number of leaves/plants, fresh leaf weight, dry leaf weight, root length and root diameter of carrot plants, in both seasons. The highest significant values for these traits were recorded as a result of increasing nitrogen fertilizer levels from 0 to 210 kg/ha regularly in both seasons. In relation to the impact of potassium fertilizer levels treatments, reveal significant effects on vegetative characteristics, in the two seasons. It is evident that the highest values were achieved as a result of increasing the potassium fertilization levels from 0 to 180 kg/ha regularly in both seasons. As for the interaction among nitrogen and potassium fertilizer levels treatments have significant effects for all vegetative characteristics, in both seasons. The most effective combined treatment, which resulted in the highest significant increase, was achieved by applying the highest nitrogen rate (210 kg/ha) along with the highest potassium rate (180 kg/ha).
