RESPONSE OF CUMIN PLANT TO SOME ORGANIC, BIOFERTILIZATION AND ANTIOXIDANT TREATMENTS II. ESSENTIAL OIL PRODUCTION AND CHEMICAL CONSTITUENTS

Abstract

The effect of farmyard manure (FYM) at 10, 15 and 20 m3/fed. Effective microorganisms (E.M.) and/or vitamin E or vit. B1 treatments on oil production (essential oil % and essential oil yield/plant and /fed) and chemical components (photosynthetic pigments content and NPK %) were investigated during 2015/2016 and 2016/2017 at Samalot region (El-Byaho village) - Minia Governorate and Laboratory of ornamental plants, Fac. of Agric., Minia Univ. All treatments of FYM statistically increased oil production as well as chemical components as compared with control. The high level of FYM was more effective in this concern. The treatments of E.M. + vit. B1 followed by E.M. + vit. E, then mineral NPK (full dose) gave the best results in increasing all previous traits. Supplying cumin plants with FYM at 20 m3/fed. in combination with E.M. + vitamins (B1 or E) or FYM at 15 m3/fed. plus E.M. + vit. B1 resulted overall the highest values of the previous traits.
