Phosphorus is required to promote flowering.
Under optimal germination rates, the seedinglevel should be 0.37 kg/ha. Final standsin the row should be 15 to 25 cm. The crop issown as early as possible, for an early start promotes flowering. Marigolds are usually grown in double rows on 75- or 100-cm beds. After the stand isestablished, water is best applied by furrow irrigation. The soil surface must be kept moist for uniformgermination and emergence irrigation by sprinkler is advised to enhanceseedling establishment and minimize soil crusting. Both overhead and furrow irrigationshould be available. Thecrop requires supplemental irrigation. Marigolds are sown directly into a finely prepared seed bed. CULTIVATIONField production of marigolds is well established, especially for the Americas,and has been studied elsewhere, particularly in South Asia (C.G. The remainingmeal was used as a source of MFP in this work ( Fig. Theresulting cake is dried, pelletized, and extracted with hexane. To remove pigment, blossoms, eitherfresh or after having been stored in silos, are pressed to remove water. Themarigold flower meal that remains after removal of the xanthophyll esters byextraction was chosen as a potential source of such a gum because it wasbelieved to contain a polysaccharide component that had the ability to protecthydrophobic substances from oxidation. Unique properties of gum arabic are its abilityto emulsify and its ability to form high-solids, low-viscosity solutions. One interest of the Whistler Center for Carbohydrate Research is to search forways to meet the need for an alternative to gum arabic, the supply of which hasbeen variable and uncertain. It is composed of esters of xanthophyll (lutein).Finely ground blossom meal, often enriched with an extract, or the extractitself, usually saponified for better absorption, is added to the feed.Marigolds are grown for this purpose in various locations in the westernhemisphere, primarily in Mexico and Peru, by and for various companies whoproduce feed additives. The pigment is added to intensify the yellow color of eggyolks and broiler skin.
Marigold ( Tagetes erecta L., Asteraceae) is not only grown as anornamental, cut flower, and landscape plant, but also as a source of pigmentfor poultry feed.
