Abstract

The experiment was conducted at the farm of the Agriculture
Faculty, Omar Al-Mukhtar University, during the growing season 2022, to
investigate the effect of humic acid by spraying it with different times on
the vegetative and fruit growth of hot pepper, the Starter variety. The experiment included the following treatments: spraying with water only (control),
spraying once (two weeks after planting), spraying twice (two weeks after
planting and three weeks after planting), and the seedlings were planted in
the field on 8th Aug. 2022, and the seedlings were 45 days old. The experiment was designed in completely randomized blocks with three replications. The vegetative traits studied were plant height, number of
leaves/plant, number of branches/plant, chlorophyll leaf content, while the
fruiting traits were fruit weight, fruit length, number of fruits/plant, and
crop weight/plant. The results showed that spraying twice three weeks after
planting recorded the highest values for all the vegetative and fruiting traits
studied, followed by spraying once two weeks after planting compared to
the control treatment, which recorded the lowest values.
