Résumé partiel
The present experiment was carried out during the summer seasons of 2014 and 2016 at the Experimental Farm of Vegetable Crops Department, Faculty of Agriculture, Assiut University, Egypt. Seedlings that were planted in the 2015 season failed to complete their germination and subsequent growth. Therefore we will only mention the results of the 2014 and 2016 sowing seasons. The experimental site is located at 270 18’ latitude and 310 18’ longitudes and at an elevation of 70 meters above sea level. The average annual rainfall is 13 mm (Ashour et al., 2015). The highest absolute minimum and highest absolute maximum annual temperatures are of 0.4oC and 47.6oC, respectively. The soil texture of the experimental site was clay with a pH average of 7.65. Three irrigation intervals and three eggplant genotypes were used. The irrigation treatments consisted of three irrigation periods : commercial irrigation treatment (W1, irrigated every 10 days), (W 2, irrigated every 20 days) and (W 3, irrigated every 30 days). The three genotypes used in the experiment were : Alabaster F1, Hanen F1 and Classic F1. The three irrigation intervals and the three hybrids of eggplants were used in this experiment to investigate the effects of irrigation intervals and eggplant genotypes on growth, yield, and quality of eggplant crops under Assiut conditions. The obtained results could be summarized as follows : The effects of the three drought intervals on average plant height were significant in the second season only. Eggplant plants irrigated every 20 or 30 days gave significantly the lowest plant height values. However, plants that were irrigated every 10 days significantly gave the tallest plants. The average plant height was significantly affected by eggplant genotypes as an average all over the three irrigation intervals. Hanen genotype significantly gave the tallest plants in the first (104.44 cm) and the second seasons (93.03 cm). The shortest plants were obtained in Classic F1 genotype (Rome) in the first (66.82 cm) and second season (71.44 cm).
