Phosphorus is an essential component of nucleic acids, phospholipids, and energy-rich phosphate compounds, thus, it plays crucial role in root growth, fruit and seed development, and disease resistance. Phosphorus deficiency can stunt plant growth

restriction is an alternative way to control growth in greenhouse crops ( Gibson et al., 2007 ; Henry et al., 2017 ; Justice and Faust, 2015 ). Phosphorus restriction has a direct effect on limiting internode elongation, resulting in more compact plants
