Thesis (Ph.D.) - Cairo University - Faculty of Agriculture - Department of Ornamental Horticulture

This study was conducted during two successive seasons (2010 / 2011 and 2011 / 2012) at the nursery of the horticulture research Institute, agricultural research center, Giza, Egypt, with the aim of studying the effect of different drip irrigation levels (applied twice weekly, at low, medium and high levels, equivalent to 2, 4, 6 L/plant, respectively) and different foliar fertilization levels, using the commercial fertilizer kristalon (19:19:19 NPK + micronutrients: 0.001% Cu, 0.25% B and 0.001% Mo), at concentrations of 0, 2, 4 and 6 g / L (referred to as control, low, medium and high rates, respectively), as well as the combinations of the irrigation and Kristalon treatments, on the growth, flowering and chemical composition of Gladiolus grandiflorus cv. peter pears and solidago canadensis cv. Tara, grown in a sandy soil under full sun light condition. The final objective of the study was to reduce the amount of water used in agricultural production, and to determine the best kristalon level for producing plants and flowers of high quality. Corms of Gladiolus grandiflorus (average weight of 15 g, and circumference of 10-12 cm) were planted on October 1st, and transplants (with about 10 leaves, and 10 cm height) of solidago canadensis were planted in mid April in both seasons
