Abstract

Twenty-one colored- and white-skin garlic genotypes from different places of the Middle Egypt were evaluated in this study for their performance in laboratory and organic farm in newly reclaimed sandy soil. Cloves of all the evaluated genotypes were planted in foam trays filled with beat moss and vermiculite soil 3:1 v/v (without chemical fertilizers). Data of the described characters were recorded after 45 days from plantation in the trays however, yield data were recorded after 180 days from the direct plantation of garlic cloves in the open field (mature stage). Results showed that these genotypes performed well under the organic agriculture in this virgin sandy soil. Most of the simple correlation coefficients values among various growth, biomass after 45 days under laboratory conditions and yield per plant under field conditions for the ten colored and eleven white genotypes for the studied characteristics were positive and significant. Yield of some of these genotypes in the open field was very acceptable and profitable. These results are very promising in which some of these genotypes can be used in organic garlic cultivations under the Middle Egypt conditions and similar environments.
