Effect of Growing Media, Bio and Chemical Fertilization on the Production of Gladiolus (Cv. Novalux) Corms From Cormlets

Abstract

The experimental trial was consummated during two successive seasons (2011/ 2012 and 2012/ 2013) at the nursery of Hort. Res. Inst., Giza, Egypt. It was intended to find out the solve of one of the most important problems faced the production of Gladiolus in Egypt, i.e. the deterioration of corms production year after year. So, the independent as well as the combined effects of different growing media (sand, sand/compost 1:1 v/v and sand/sewage sludge 3:1 v/v), fertilization treatments (NPK at 1:2:1, kristalon and EM 5%) and their interaction were investigated on the production of Gladiolus corms from cormlets locally. The results indicated that growing cormlets in sand/compost (1:1 v/v) medium proved its mastery in raising corms yield, corm fresh and dry weights, corm circumference and root length of corm as well as cormlets yield and quality in both seasons. Meanwhile, using sand medium in plantation achieved the second rank in improving the same parameters in the same seasons. Results indicated also the prevalence of all corms and cormlets parameters due to applying the mixture of N, P and K, whereas kristalon and EM 5% showed less effect in this regard. Chemical constituents of the new formed corms were also affected by the previous treatments, where growing cormlets in sand/compost medium showed its superiority in raising N, P and K as well as total carbohydrates content in the new corms. Also, NPK fertilization revealed an increment on the same parameters in the same organ. From the aforementioned results and interactions, it could be recommended to grow Gladiolus (cv. Novalux) cormlets in sand/compost medium along with treating the plants with NPK mixture at a ratio of 1: 2: 1 at the rate of 2 g/pot, 8 times at 15 day intervals to obtain high yield and quality of the new formed corms.

Effect of nano, bio, chemical fertilization and leaves extract of moringa plant on flowering and chemical constituents of gladiolus plant

“…In general, N, P and K nutrients (whether traditional or nano) play a vital role in enhancing gladiolus growth and development as reported by a lot of authors e.g. [38], [39], [40], [41], [26], [42], [43], [44]. In this regard [45][46] reported that mineral NPK fertilization increased both flowering parameters (length of spike, rachis length, number of florets/spike, first floret diameter and fresh weight) and some chemical constituents (N, P, K and total sugars % in corms and total chlorophyll in leaves).…”

Stimulative Effects of Seaweed and Active Yeast Extracts as Foliar Treatments on Growth and Productivity of Gladiolus Grandiflorus Andrews ‘White Prosperity’

“…To meet the production demand from gladiolus as a famous beloved cut flower all over the world, the availability of high-quality corms is a prerequisite matter. Local production of gladiolus corm in Egypt has deteriorated year after year, as it has been reported by several specialists and authors such as Khattab et al (2016) and Bazaraa (2014). Accordingly, gladiolus cut flower production in Egypt has depended on the annually imported corms from the Netherlands.…”

Effect of Some Fertilizer Treatments on the Growth of Cormels of Gladiolus and Corms Production

“…Novalux concluded that, actosol treatment at 2.5 ml/l as a soil drench proved its superiority in increasing corms quality. Additionally, Bazaraa et al (2014) on Gladiolus cv. Novalux.…”
