Mineral Composition and Soil-Plant Relationships for Common Guava (Psidium guajavaL.) and Yellow Strawberry Guava (Psidium cattleianumvar. lucidum) Tree Parts and Fruits

Abstract

The mineral compositions of the fruit and tree parts of common guava, Psidium guajava L., and strawberry guava, Psidium cattleianum var. lucidum, were determined. The study occurred during three seasons at six locations in Hawaii to assess guava as feed for livestock. Guava bark contained the greatest concentrations of calcium (Ca) and ash; leaves the greatest concentrations of magnesium (Mg), sulfur (S), sodium (Na), boron (B), and manganese (Mn); and the shoots had the greatest concentrations of nitrogen (N), phosphorus (P), and potassium (K). The leaves and the shoots had the greatest concentrations of copper (Cu) and iron (Fe). Between guava and waiwi, guava had greater concentrations of most minerals except for Na in all plant parts, and Mg and ash in the leaves. Guava leaves and shoots meet the macromineral requirements for various phases of sheep, goat, and beef cattle life cycles with the exception of P and Na. Guava shoots do not meet Mn requirements for lactating cows.

Psidium cattleianum fruits: A review on its composition and bioactivity

“…Different groups of researchers studied the mineral composition of mature and immature yellow araçás (Table 1). Araçá from Hawaii, regardless the maturation stage, was rich in macrominerals such as potassium (1.30-1.59%) and nitrogen (0.85-0.91%), and microminerals such as iron (0.0016-0.0043%) and zinc (0.0011-0.0050%) (Adrian, Arancon, Mathews, & Carpenter, 2015). Similar results were obtained for yellow and red mature araçá in Brazil (Kinupp and Inchausti, 2008;Silva, Santos, Mendes, & Martins, 2008).…”

Antioxidant and Anti-Cytotoxicity Effect of Phenolic Extracts from Psidium guajava Linn. Leaves by Novel Assisted Extraction Techniques

“…Fucose is crucial for host–microbe interactions, selectin-mediated leukocyte-endothelial adhesion, and blood transfusion responses [ 71 ]. GLs are abundant in minerals such as calcium, potassium, sulfur, sodium, iron, boron, magnesium, manganese, and vitamins C and B. GLs are an excellent choice for human nutrition and animal feed to reduce micronutrient deficits due to their enhanced Mg, Na, S, Mn, and B concentrations [ 72 ]. According to Thomas et al [ 67 ], 100 g of GL contains 1660 mg Ca, 360 mg P, 1602 mg K, 13.50 mg Fe, and 440 mg Mg per 100 g of GL (dry weight).…”

Guava (Psidium guajava L.) Leaves: Nutritional Composition, Phytochemical Profile, and Health-Promoting Bioactivities

“…Guava leaves are the rich source of minerals, such as calcium, potassium, sulfur, sodium, iron, boron, magnesium, manganese, and vitamins C and B. The higher concentrations of Mg, Na, S, Mn, and B in GLs makes them a highly suitable choice for human nutrition and also as an animal feed to prevent micronutrient deficiency [ 26 ]. Thomas et al [ 23 ] reported the concentration of minerals such as Ca, P, K, Fe, and Mg as 1660, 360, 1602, 13.50, and 440 mg per 100g of guava leaf dry weight (DW), respectively.…”
