“…Among the three compost treatments, the high level treatment (7.5 ton/fed) resulted the highest values for all corm and cormels production over both low and medium compost treatments in the two seasons. Similar results were also revealed on gladiolus plants by Ruppenthal and Castro (2005), Chandar et al (2012), Pradeep et al (2014) Sankari et al (2015, Hassan (2016) and Khanam et al (2017).…”

Two field experiments were conducted to investigate the effect of plant compost (0, 2.5, 5.0 and 7.5 ton/fed) and six natural stimulants (green tea extract at 5 g/l, moringa leaves extract at 300 mg/l, garlic extract at 300 mg/l, licorice roots extract at 5 g/l, active dry yeast at 5 g/l and seaweeds extract at 3 cm 3 /l) on corms production and chemical constituents of Gladiolus grandiflorus cv. Peter Pears. The obtained results indicated that corm diameter, number of cormels/plant, dry weight of cormels, as well as, chemical constituents including chlorophyll a, b, carotenoids and percentages of N, P and K in the corms were gradually increased by increasing the level of compost. Significant differences were detected among the four used treatments. So, the high level of compost resulted the highest values. All six treatments of natural stimulants significantly increased corm and cormels production and their content of chemical constituents in comparison of the control plants. The highest values were obtained due to the treatments of seaweeds extract at 3 cm 3 /l. or active dry yeast at 5 g/l. The interaction between compost and natural stimulants was significant for all previous characters, except chlorophyll a in the first season.

The aim of this study was to figure out the effect of organic fertilization and natural stimulants, as well as, their interaction on vegetative growth, flowering aspects of Gladiolus grandiflorus cv. Peter Pears plants. Results showed that vegetative growth (leaf length, number of leaves/plant and dry weight of leaves/plant) and flowering aspects (length of spike, number of florets/spike and lower floret diameter) were gradually increased by increasing the level of compost fertilizer. All natural stimulant treatments significantly increased all vegetative growth characters and flowering parameters in comparison with the control. Seaweeds extract at 3 cm 3 /l or active dry yeast at 5 g/l seemed to be more effective than other treatments in this concern. The use of high level of compost (7.5 ton/fed) in combination with seaweeds extract at 3 cm 3 /l or active dry yeast at 5 g/l noticeably improved the different vegetative growth characters and flowering parameters of gladiolus.

“…These results are in parallel with those of Mazhar et al (2012) who studied the effect of four concentrations of humic acid (0, 1, 1.5 and 2%) used as a foliar spray on flower parameters of chrysanthemum plant and found that humic acid (2%) gave a significant increase in flower number. Also these results are in harmony with those obtained by Pradeep et al (2014) on gladiolus, and Palanisamy et al (2015) on gerbera plants. Also these results are in harmony with those obtained by (Attoa, 2008 ;Deljou and Gholipour, 2014) who studied the effect of calcium spray on flower characters of gerbera plants.…”

This study was conducted in lath house, Horticultural Department, College of Agriculture, University of Baghdad-Jadriya, Iraq during the spring and fall seasons of 2015 to investigate the influence of foliar application of humic acid and calcium chloride on "Yanara" gerbera cultivar. This study included two factors; humic acid spray (H) and calcium chloride spray (Ca). The first factor was represented by four levels which were; 0 (H 0), 5 (H 5), 7.5 (H 7.5) and 10 ml.l-1 (H 10) and four levels of calcium chloride; 0 (Ca 0), 50 (Ca 50), 100 (Ca 100) and 150 mg.l-1 (Ca 150). Data were recorded during spring and fall seasons. The experimental results showed that spraying plants with humic acid at 10 ml.l-1 and calcium chloride at 150 mg.l-1 (H 10 Ca 150) gave the highest values of flower number/plant (3.60 and 6.87), flower diameter (8.71 and 11.33 cm), vase life (11.90 and 11.34 day) for both seasons, respectively. The lowest values of these parameters were recorded with control treatment (H 0 Ca 0). It could be concluded that spraying plants with humic acid at H 10 and calcium chloride at Ca 150 had improved flower characteristics in gerbera plant cv. Yanara.
