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.

to study the effect of compost (7.5, 10.0 and 12.5 ton/fed) and seven treatments of stimulatory substances i.e. control, seaweeds extract (300 ppm), amino acids (200 ppm), ascorbic acid (100 ppm), salicylic acid (50 ppm), active yeast (5 g/l) and Minia azotein (50 ml/plant), as well as, their interaction on corms and cormels productivity of gladiolus and some chemical composition constituents. The obtained results indicated that the three levels of compost significantly increased corm diameter, number of cormels/plant, fresh weights/plant, as well as, chemical composition (photosynthetic pigments and N, P and K%) as compared to control. The maximum values were obtained by using compost at 12.5 ton/fed. Treated plants with any of six used stimulatory treatments considerably increased corm and cormels productivity and chlorophyll a, b and carotenoids content, as well as, the percentage of N, P and K in the leaves. Minia azotein was the most effective than the other treatments in this concern the interaction treatments were obtained due to fertilizing gladiolus with compost at 12.5 ton/fed and inoculation of the soil with either Minia azotein or with the sprayed plants with active yeast.

“…These results may be attributed to the increase in nutrient elements and/or positive role of organic fertilizer on the physical and chemical properties of the soil, that reflected on the growth and the pigments content. In harmony with these results regarding organic fertilization treatments were those mentioned by Abdou et al (2013), Khalil (2015), Abdou et al (2018) and Abdou et al (2019) on gladiolus, El-Naggar and El-Nasharty (2009) on Hippeastrum vittatum and Dalawai and Naif (2017) on Dianthus caryophyllus.…”

IMPACTS OF COMPOST, BIOFERTILIZER AND/OR SOME ANTIOXIDANT TREATMENTS ON GLADIOLUS (GLADIOLUS GRANDIFLORAS) B. Corms and cormels production and some chemical constituents

Gladiolus is commercially propagated by its underground structure for production of flowers and corms as well as cormels. A field experiment was conducted during two successive seasons of 2018/2019 and 2019/2020 to investigate the effects of compost as an organic fertilizer (0, 5, 10 and 15 ton/fed) and Microbein biofertilizer (M.B.) at 50 ml/plant and/or some antioxidant treatments (salicylic and ascorbic acids) on corm and cormels production and chemical constituents of Gladiolus grandiflorus var. Jester plants. The obtained results indicated that corm diameter (cm), number of new cormels/plant, dry weight of corm and cormels (g), as well as, chemical constituents including chlorophyll a, b, carotenoids in the fresh leaves and percentages of N, P and K in the dry leaves were gradually increased by increasing levels of compost with significant differences. The highest corm diameter (5.27 cm) was produced by plants received compost at 15 ton/fed in combination with Microbein biofertilizer (M.B.) plus salicylic acid plus vitamin C while least size (2.5 cm) of corm was observed in control plants. All six treatments of Microbein biofertilizer (M.B.) at 50 ml/plant and/or some antioxidant (salicylic and ascorbic acids) treatments each at 50 ppm significantly increased corms and cormels production and the content of chemical constituents in comparison with control treatments. Treatments of Microbein biofertilizer (M.B.) plus salicylic acid plus ascorbic acid (vit. C) was more effective than other treatments for corm and cormels production, as well as, photosynthetic pigments content (mg/g. F.W.) and the percentage of nitrogen, phosphorus and potassium, in most cases. The interaction between compost, Microbein biofertilizer (M.B.) and/or some antioxidant (salicylic and ascorbic acids) treatments were significant for all previous characters. In some cases, the highest values of corms and cormels production were achieved by compost (15 ton/fed) in combination with Microbein biofertilizer (M.B.) plus salicylic acid plus ascorbic acid (vit. C) followed by 15 ton/fed compost with M.B. + vit. C then 10 ton/fed compost with M.B. + salicylic acid + vit. C which recorded the highest contents of pigments and elements of N, P and K.
