EFFECT OF CULTIVAR AND LOCATION ON YIELD, TUBER QUALITY, AND STORABILITY OF JERUSALEM ARTICHOKE (HELIANTHUS TUBEROSUS L.) I. GROWTH, YIELD, AND TUBER CHARACTERISTICS

This study was carried out at the Strawberry and Non Traditional Crops Improvement Center, Ain Shams University, Cairo, Egypt during the two successive seasons of 1998 and 1999 in two experimental farms, Shoubra El-Khema, El-Kaluobia governorate and South Tahrir, El-Behiara governorate.
This study aimed to investigate the effect of cultivar and location on vegetative growth, total yield and physical and chemical components of jerusalem artichoke tubers. Cultivars ‘Fuseau’ and ‘Local’ were cultivated in two different locations (El-Kaluobia and El-Behiara). A complete randomized block design with four replicates was adopted.
Data were recorded on vegetative growth, total tubers yield, tuber quality characters, and some chemical components of the tubers.
Results indicate that ‘Local’ could be considered a promising cultivar; it exhibited high vegetative growth characters, total yield, average tuber weight and average tuber size.
Moreover, El-Kaluobia location affected positively vegetative growth, while it did not affect total tuber yield.
In respect to the interaction between cultivar and location, the highest total tubers yield was obtained from ‘Local’ planted in El-Behiara.
