Efficacy of vermicompost and/or plant growth promoting bacteria on the plant growth and development in gladiolus

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.

“…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.

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

2020

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.

“…The effect of organic fertilization on increasing corm diameter, number of cormels and dry weight of corm and cormels of gladiolus were reported by many investigators, such as Abdou and Ibrahim (2015) and Karagöz et al (2019) on gladiolus, Abd El-Karim (2001), Abdel-Sattar et al (2010), Srivastava et al (2014) and Pattnaik (2016) on tuberose, El-Naggar and El-Nasharty (2009) on Hippeastrum vittatum, El-Sayed et al (2012) on Freesia and Prasad et al (2017) on lily plant who stated that improved the chemical composition of gladiolus plants as well.…”

Influence of Organic Manure, Biofertilizer and/or Some Vitamin Treatments On: B. Corm and Cormels Productivity and Some Chemical Constituents of Gladiolus Grandiflorus Var. Gold Field Plants

et al. 2019

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%.
