Abstract

A filed experiments was carried out during two successive seasons
of 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 of
antioxidant (ascorbic acid)at rates 0, 5, 10 and 15mM./L, either alone or
in combination with each other on growth, yield and some chemical
constituents of caraway (Carum carvi L.,) plants. The obtained results
indicated that, all growth parameters i.e., plant height, number of
branches, number of compound umbels /plant; yield and its components
i.e. fruits yield per plant or feddan, fruit oil %, fruit oil yield per plant
and, or feddan , as well as some chemical constituents i.e. chlorophyll a,
b , total caroteniods, nitrogen, phosphorous and potassium % in herb
and total carbohydrates, total nitrogen and total protein% in fruits were
significantly increased as a result of applied farmyard manure and
ascorbic acid either added alone or in combination with each other. The
best results were obtained by applying the middle rates of FYM and
high (25 & 35 m3/fed) and ascorbic acid 10 & 15 mM. /L) either added
alone or in combined with each other, with insignificant differences.
These treatments were statistically almost equal for producing
significant values than the other treatments in the two studied seasons.
From the economical point of view, the maximum increments in all
studied growth parameters and chemical constituents as well as yield
and its component were obtained by fertilization with farmyard manure
at rate 25 m3/fed. combined with foliar spray by ascorbic acid at rate
10mM./L under the prevailing conditions of the current expermint.
