Abstract: A filed experiments was carried out during two successive seasonsof 2005/2006and 2006/2007 to study the effect of farmyard manure(FYM) at rates 0, 15, 25 and 35 m3/fed. or foliar spray with applied ofantioxidant (ascorbic acid)at rates 0, 5, 10 and 15mM./L, either alone orin combination with each other on growth, yield and some chemicalconstituents of caraway (Carum carvi L.,) plants. The obtained resultsindicated that, all growth parameters i.e., plant height, number ofbranches, number of compound umbels /plant; yield and its componentsi.e. fruits yield per plant or feddan, fruit oil %, fruit oil yield per plantand, or feddan , as well as some chemical constituents i.e. chlorophyll a,b , total caroteniods, nitrogen, phosphorous and potassium % in herband total carbohydrates, total nitrogen and total protein% in fruits weresignificantly increased as a result of applied farmyard manure andascorbic acid either added alone or in combination with each other. Thebest results were obtained by applying the middle rates of FYM andhigh (25 & 35 m3/fed) and ascorbic acid 10 & 15 mM. /L) either addedalone or in combined with each other, with insignificant differences.These treatments were statistically almost equal for producingsignificant values than the other treatments in the two studied seasons.From the economical point of view, the maximum increments in allstudied growth parameters and chemical constituents as well as yieldand its component were obtained by fertilization with farmyard manureat rate 25 m3/fed. combined with foliar spray by ascorbic acid at rate10mM./L under the prevailing conditions of the current expermint.
