Abstract

A field experiments was conducted in sandy soil at South EI-Tahrir province
during two successive seasons to study the influence of macro and micronutrients.on
dry matter yield, oil content and nutrient contents and uptake of sweet basil plants
(ocimum basilicum L.)
Results show that basil plant height was significantly affected by the applied fertilizer
(NPK, Fe, Mn and Zn) either at the first or second cut.
*) Micronutrients fertilizers generally showed a beneficial influence on enhancing the
dry matter yield of leaves and stems in the two seasons.
*) The best treatment in increasing oil % was the chelated Zn, Mn, Fe + NPK.
*) Application of NPK and the used micronutrients (Fe, Mn and Zn) remarkably
increased Nand P concentration either in the first and second cut of basil plants or
in the first and the second season of planting. The same trend was found in
nitrogen and phosphorus uptake.
*) Zn application in the form of EDTA showed the highest effect in augmenting K
concentration and uptake.
*) Application of micronutrients and NPK pronouncedly augmented the iron content
and uptake by basil plant leaves.
*) Zn and Mn application in chelated forms increase Zn and Mn concentration in
plants.
