The aim of this research was to determined the role of humic acid (HA) and organic
fertilization (poultrey with cattle manure) on vegetative growth, flowering and cormels
production of Gladiolus (Gladiolus hybrida). Also investigating the ablity of
this organic
manure to provide nutrients for the plant in order to reduce the mineral fertilization.
Humax (50% humic acid) was used, and three applications of HA applied at 2 leaf, 2 and 4
leaf, and 2, 4 and 6 leaf stages of plant development.
The results showed that the use of humic acid had a positive impact on vegetative
growth (plant height and average number of leaves on the plant) it also showed a positive
effect on the formation of Spikes and flowering (early flowering, spike length, number of
flowers on spike).The positive effects were reflected on the proportion of dry matter in the
vegetative part.
The results indicated that plants sprayed with humic acid in presence of Chicken
manure produced higher cormels yield and economic profit than the control and those
fertilized with Cow manure. . Data also, Showed that T4 treatment (plants sprayed 3 times)
realized higher economic profit than authors treatment (112,66%).
The research was carried out at Jeb Ramlah Research Station – AlGhab Research Center -
General Authority of Scientific Agricultural Research at 2017 growing season. The
objective was to investigate the effect of three organic and bio fertilizers (B
acillus, Humic
acid and Amino acids) and three fertilization methods (Soaking seeds, Vegetative spraying
and Plant irrigation) in some morphological and production traits of cotton cultivar 124
(Gossypium herutum L.) The experiment was conducted according to RCBD with three
replications. The first factor (fertilizer type) occupied the main plots, while the second
factor (fertilization method) occupied the split plots. Statistical analysis was carried out
using the Genestat.12 software and the least significant difference L.S.D. at 5% level was
calculated. Studied traits included (at the beginning of Blooming stage): Plant Height,
Plant wet weight, Plant dry weight, Leaf area and plant production of cotton. The results
showed that the average of treatment of amino acids was superiority significant on the
others in terms of plant height (70.70cm), Plant wet and dry weight (201.50, and 83.41g),
respectively, Leaf area (4240.15cm2/plant) and plant production of cotton (75.13g). For
fertilization method, Vegetative spraying average was superiority significant on the others
in terms of all studied traits.
