Influence of Organic Manure, Biofertilizer and/or Some Vitamin Treatments On: A. Vegetative Growth and Flowering Aspects of Gladiolus Grandiflorus Var. Gold Field Plants

Abstract

A field experiment was carried out during the two successive seasons of 2016/2017 and 2017/2018. The aim of this study was to investigate the effect of farmyard manure (FYM) at four levels (0, 10, 15 and 20 m 3 /fed) in combination with Minia Azotein (M.A.) at 50 ml/plant and/or some vitamins (E and C) each at 50 ppm, in addition to the control on vegetative growth and flowering of Gladiolus grandiflorus var. Gold Field plants. Results showed that 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 by increasing the levels of farmyard manure with significant differences were detected between successive treatments. Also, Minia Azotein (M.A.) and/or some vitamins (E and C) treatments significantly increased all vegetative growth and flowering parameters in comparison with the control. Minia Azotein (M.A.) plus vitamins E and vitamin C were more effective in this concern. It was found also that the use of FYM (20 m 3 /fed) in combination with Minia Azotein (M.A.) plus vit. E and 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 noticeably improved the different vegetative growth and flowering parameters of gladiolus plants.

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

“…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.…”

“…and some antioxidant (salicylic and ascorbic acids) treatments are among the important agricultural treatments which have been proved to improve corm and cormels production of gladiolus plants. The effect of organic fertilization on increasing corm diameter, number of new cormels and dry weight of corm and cormels of gladiolus were reported by many investigators, such as Ahmed (2013), Abdou et al (2018), Abdou et al (2019) and Karagöz et al (2019) on gladiolus, Kabir et al (2011), Srivastava et al (2014) and Suseela et al (2016) on tuberose, Mirkalae et al (2013) and Prasad et al (2017) on lily, Pandey et al (2017) on dahlia plant who found that compost fertilizer improved the chemical composition of gladiolus plants. Microbein biofertilizer (M.B.)…”

“…Microbein biofertilizer (M.B.) treatments were found to have stimulating effect on corm and cormels production and chemical composition of gladiolus such as those raveled by Srivastava and Govil (2005), Kashyap (2016), Sathyanarayana et al (2018) and Chakradhar et al (2019) In regard to the roles of salicylic acid in increasing corm and cormels production, as well as, chemical constituents were mentioned by Pawar et al (2018) The vegetative attributes, flower and corm production in gladiolus could be positively influenced by different organic fertilizers treatments when applied in optimum concentration (Abdou et al, 2019;Ahmed and Rab, 2019). Good quality corms result in better vegetative growth with healthy foliage and enhanced photosynthetic activity (Sarkar et al, 2014).…”

“…Production of both, flowering spikes and corms depends upon the size of mother corm and or cormels (Bose et al, 2003;Chourasia et al, 2015). Therefore, the vegetative characteristics, flower and corm production in gladiolus could be absolutely affected by different organic and bio-fertilizers in combination with antioxidants treatments when applied in optimal concentration (Abdou et al, 2019). Good quality corms give rise to better vegetative growth with healthy verdure and boosted photosynthetic activity (Sarkar et al, 2014;Ahmed and Rab, 2019).…”

“…In Egypt, the year-round production of cut flower crops is a nature's boon, due to the country has varied agro-climatic conditions. Different gladiolus varieties as cut flowers are important cut flower crops used in flower arrangements, in making bouquets, garden display and in beautifying any landscape (Abdou et al, 2019). However, various stress factors are associated with any flower crop that directly and indirectly hampers the growth of plant and results in poor quality flower, deprived yield and low income.…”
