The effect of spraying amino acid fertilizer on the growth characteristics and mineral content of pomelo (Citrus grandis) seedlings

This study aimed to investigate spraying two organic fertilizers viz. Delfan plus and Vegeamino, which contain amino acids, on the vegetative growth of pomelo seedlings using concentrations of 0, 1, 2, 3, and 4ml/l. The study was designed according to a completely randomized block design, and each treatment was repeated three times, and one experimental unit included four seedlings. The results showed that the application of organic had containing amino acids especially at the levels of 3 and 4 ml/l of Vegeamino, which achieved a significant increase in all the studied traits except the zinc content of the leaves.
