Effect of irrigation frequency and selenium fertilization on the vegetative growth and biomass yield of Moringa oleifera and Moringa peregrina

Sci Rep. 2022 Dec 26;12(1):22379. doi: 10.1038/s41598-022-26967-5.

ABSTRACT

To maximize the production value of Moringa species, there is a need to understand the morphological effect of irrigation frequency and Se fertilizer levels on Moringa species’ growth and development. Hence, the aim of this trial was to determine the combined effect of irrigation frequency and Selenium (Se) fertilizer levels on the growth of Moringa oleifera (M. oleifera) and Moringa peregrina (M. peregrina) in the central region of the Kingdom of Saudi Arabia. A split-plot arrangement was used, where the treatments were arranged in a Completely Randomized Block Design (CRBD) with three replicates, as the study included two plant species (M. oleifera and M. peregrina), four irrigation frequencies (7, 10, 15, and 20 days), and three Se levels (0.0, 12.5 and 25 mg/L foliar spray). M. peregrina showed slow emergence and plant establishment as compared to M. oleifera. The results indicated that plant height, leaves and stems fresh weight increased with the increase in Se level, and were highest when the two plant species were irrigated every 10 days which surpassed all other irrigation frequencies. The findings of this research study indicated that the two Moringa species, particularly M. oleifera could successfully be grown using drip irrigation at a 10-days irrigation frequency.
