| 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. | ||||
