“…Moringa (Moringa oleifera Lam.) is cultivated for multiple purposes because all its parts including seeds, stems, shoots, leaves, flowers, fruits and roots are useful [7]. Leaves with high protein and seeds contain 30 to 40% oil that is high in oleic acid, while degreased meal is 61% protein [8].…”

For evaluation of moringa growth and its minerals content response to irrigation with diluted seawater and spraying by potassium silicate solitary (Si) or in combination with salicylic acid (Si+SA), a pot experiment was conducted in the greenhouse of the National Research Center, Cairo, Egypt. Negative relationship was shown between salt stress degree and plant growth characters i.e. plant height, leaves area and dry weight of root, stem and leaves, which decreased as the salt concentration increased in the diluted seawater. Nevertheless, shoot/root ratio and leaf water content were increased with salinity increased. All growth characters increased with Si+SA addition. While adding sole silicate gave more plant height than the combined application without significant difference between them. The highest positive effect was shown when plants irrigated by tap water and spraying with Si+SA together. Significant depressions were obtained in nitrogen concentration or content as a result of growing moringa plants under salinity condition. Similar response in P content but the differences were not significant. Calcium and K concentrations did not significantly responded with salinity but Mg concentration decreased significantly only with the first level of salinity. Calcium showed its higher

“…Tryptophan is an α-amino acid and contains an α-amino group, an α-carboxylic acid group, and side chains, making it a very important amino acid [11]. Tryptophan is one of the essential amino acids required for plant growth since it is involved in the biosynthesis of the natural auxins indole acetic acid (IAA) that have an impact on plant growth, yield, and chemical compound content [12,13]. Foliar application of tryptophan has been shown to improve the vegetative growth and chemical content of Pelargonium graveolens L. [14], Philodendron erubescens plants [15], Gladiolus plants [16,17], wheat plants (Triticum aestivum) [18], Lupine (Lupines termis L.) plants [19] and Moringa oleifera seedlings [20].…”

Researchers from the College of Agriculture at the University of Kerbala in the Karbala province of Iraq used a greenhouse to examine the effects of nano-potassium and the amino acids tryptophan and glycine on the development of the stevia plant and the concentration of its active substances in the local climate. The experiment had three replicates and was carried out using a factorial trial design within a randomized complete block design (R.C.B.D). The study had three variables. The first component was tryptophan, with three concentrations (0, 25, and 50 mg. L-1), the second factor was glycine, with three concentrations (0, 500, and 1000 mg. L-1), and the third factor was nano-potassium, with two values (0, and 100 nmol L-1) (0, 2 g. L-1). The findings demonstrated that the variables under study, whether acting separately or in combination, significantly improved all characteristics of vegetative development. The triple interaction treatment (50 mg. L-1 tryptophan + 1000 mg. L-1 glycine + 2 g. L-1 potassium) gave the highest percentages for plant height, number of main branches, leaf dry weight, number of total leaves, and total chlorophyll content, where recorded (89.68 cm, 12.67 main branches. plant-1, 48.43 g. plant-1, 189.09 leaves. plant-1, 12,609 mg. 100 g-1 fresh weight, respectively). It may be concluded that the application of an integrated fertilization program can sustain or enhance stevia production in both quantity and quality under challenging environmental circumstances.

Two pot trials were conducted during the period of February 15 -October 15 of 2012 and 2013 seasons at two different locations, to evaluate the effect of soil type, sowing date and diluted seawater irrigation on: germination percentage in the first trial and on both plant vegetation and leaves chemical constituents of moringa (Moringa oleifera, Lam.) in the second one. The results showed that, generally, Kafr El-Sheikh area (Agricultural area where clayey soil and Nile River water is available) outperformed Balteem area (coastal area where soil is silty clay and seawater is available) in most studied characters. Lowest seawater ratios in Moringa oleifera irrigation water gave the best results for germination %, growth characters and some chemical and mineral contents as total green color, leaf protein, total carbohydrates, nitrogen, potassium, calcium and magnessium whereas, the highest ratios gave the best results for phosphorus and sodium contents.
