Effect of Some Clean Agricultural Treatments on Fruit Yield, Active Ingredients and Chemical Composition of Ammi visnaga, L.

Abstract

A field experiment was carried out at the Experimental Farm. of Fac. Agric. Minia Univ. during two seasons (2011/2012 and 2012/2013) to study the effect of compost (0, 5, 7.5 and 10 ton/fed.) and eight biostimulant treatments (E.M., S.A., vit. E, E.M. + vit. E, E.M. + S.A., S.A.+ vit. E, E.M. + S.A. + vit. E and control) on Ammi visnaga, L. plants. The data showed that using 10 ton/fed. compost significantly increased fruit yield /plant, khellin and visnagin contents and chemical composition (N, P and K %) comparing with other treatments. Treating plants with E.M., S.A., vit. E and all possible mixtures significantly increased fruit yield, active ingredients and percentages of N, P and K comparing with control treatment. The best treatments were E.M. + S.A. + vit. E following by E.M. + vit. E in this concern. It may be recommended to use compost at the level of 10 ton/fed. and treating the plants with the triple a mixture (E.M. + S.A. + vit. E) or the dual mixture (E.M. + vit. E) to give the highest values of fruit yield and active ingredients (khellin and visnagin) of Ammi visnaga plants.
