Abstract
The study was carried out in Central Laboratory for Agriculture Climate (CLAC), Agriculture Research Center (NRC), Egypt.
This study was conducted for two successive seasons (2001-2002) to investigate the effect of different soilless culture systems on production and quality of cantaloupe (Cucumis melo L.) cv.
Regal grown under protected cultivation.
Two methods of cultivation (horizontal bags and vertical bags) and two substrates (perlite and pumice) were tested in comparison with the Nutrient Film Technique (NFT). The electrical conductivity (EC) of the nutrient solution was maintained between 2-2.5 m mhos cm-1, 1.8-2.0 m mhos cm-1 in NFT and substrate respectively, while pH adjusted between 5.5 and 6.5.
Vegetative growth (number of leaves, plant height and leaf area), physical quality of fruits (firmness, flesh thickness, fruit diameter, number of fruits/plant, mean productivity/plant), chemical quality of fruits (TSS, total acidity and vitamins C) were recorded.
Results showed that NFT gave the best vegetative growth, yield and quality.
Regarding the substrates using pumice in horizontal bags and vertical bags gave higher vegetative growth; yield and quality than perlite in horizontal bags.
The differences among them were significant.
