Response of Tuberose Plants (Polianthes Tuberosa L.) to Chemical and Bio Fertilization and Their Effect on Vegetative Growth, Flowering and Chemical Composition Under Sandy Soil Conditions

A field experiment was conducted to investigate the effect of plant farmyard manure (FYM) as an organic fertilizer (0, 10, 15 and 20 m 3 /fed) and Minia Azotein (M.A.) at 50 ml/plant and/or some vitamins (E and C) each at 50 ppm on corm and cormels productivity and chemical constituents of Gladiolus grandiflorus var. Gold Field plants. The obtained results indicated that corm diameter (cm), number of cormels/plant, dry weight of corm and cormels (g), 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 levels of FYM. Significant differences were detected among the four used treatments. So, the high level of FYM resulted the highest values. All six treatments of Minia Azotein (M.A.) and/or some vitamins (E and C) significantly increased corm and cormels productivity and their content of chemical constituents in comparison to the control plants. The treatments of Minia Azotein (M.A.) plus vit. E plus vit. C was more effective than other treatments for corm and cormels productivity, as well as, photosynthetic pigments content (mg/g. F.W.) and the percentages of nitrogen, phosphorus and potassium, in most cases. The interactions between farmyard manure (FYM), Minia Azotein (M.A.) and/or some vitamins (E and C) treatments were significant for all previous characters, except for K %. In most cases, the highest values of corm and cormels productivity were achieved by FYM (20 m 3 /fed) in combination with Minia Azotein (M.A.) plus vit. E plus vit. C followed by 20 m 3 /fed FYM with M.A. + vit. C then 15 m 3 /fed FYM with M.A. + vit. E + vit. C which recorded the highest contents of pigments and elements of N and P%.

A field experiment was carried out during two successive seasons of 2018/2019 and 2019/2020 at the Nursery of Ornamental plants, Faculty of Agriculture, Mania University. The aim of this study was to investigate impacts of compost at four levels (0, 5, 10 and 15 ton/fed) in combination with Microbein biofertilizer (M.B.) at 50 ml/plant and/or some antioxidant treatments (salicylic and ascorbic acids) on vegetative growth and flowering of Gladiolus grandiflorus var. Jester plants. Results showed that vegetative growth and flowering parameters of leaf length (cm), number of leaves/plant, leaves dry weight/plant (g), length of spike (cm), spike diameter (mm), spike fresh weight (g), number of florets/spike, lower floret diameter (cm) and lower floret fresh weight (g) were gradually increased with significant differences by increasing levels of compost. In addition, Microbein biofertilizer (M.B.) and/or some antioxidant (salicylic and ascorbic acids) treatments significantly increased all vegetative growth and flowering parameters in comparison with control treatment. Microbein biofertilizer plus salicylic acid and ascorbic acid were more effective in this concern. It was found also that the use of compost (15 ton/fed) in combination with Microbein biofertilizer plus salicylic acid plus ascorbic acid followed by 15 ton/fed with M.B. plus ascorbic acid then 10 ton/fed with M.B. plus salicylic acid plus ascorbic acid noticeably improved different vegetative growth characters and flowering parameters of gladiolus plants. As the most important characters for the quality of gladiolus, the largest length of spike (season one 65.76 cm and season two 65.76 cm), largest number of florets/spike (season one 11.65 and season two 11.98) and the highest lower floret diameter (season one 7.79 cm and season two 8.34 cm) were achieved with compost (15 ton/fed) in combination with Microbein biofertilizer plus salicylic acid plus ascorbic acid. From the results of this study, it could be concluded that adaptability of gladiolus corms of Jester variety (Gladiolus gradiflorus) to the Egyptian environmental conditions is confirmed.

“…Many authors evaluated the effect of biofertilizer such as, El-Sayed (2004), Taha and Hassan (2008), Abdou and Ibrahim (2015), Mazhar and Eid (2016), Sathyanarayana et al (2018) and Hassan and Abd El-Azeim (2020) on gladiolus and Attia et al, (2018) on tuberose plants. Hassan (2016) on gladiolus and Afifpour and Kosh-Khui (2015) on Polianthes tuberosa found that amino acids have positive effect on N, P and K %.…”

Effect of Compost and Some Stimultory Substances on Gladiolus Plant B. Corms and Cormels Productivity and Chemical Composition

et al. 2021

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.
