ABSTRACT
The different levels of moisture regimes significantly affected the height, number of leaves per plant and leaf area per plant of gladiolus at 75 days after planting (DAP). Significantly taller plants with more number of leaves and leaf area were produced with the application of 1.0 IW:CPE ratio (I3) maintained through drip. Fertigation at 80 per cent RDF recorded significantly higher plant height, number of leaves and leaf area per plant at 75 DAP.
Application of 1.0 IW:CPE ratio (I3) through drip resulted in non-significantly higher values of number of days required for spike initiation and first floret opening as well as number of spikes per plant, blooming period and vase life of gladiolus. Application of 100 % RDF through drip produced significantly higher number of days required for spike initiation and first floret opening but, number of spikes per plant, blooming period (days) and vase life (days) of gladiolus were more with 80 per cent RDF. Significantly more spike length, number of florets per spike and number of florets opened at a time were recorded with 1.0 IW:CPE ratio (I3) maintained through drip. Fertigation @ 80 per cent RDF recorded significantly higher spike length, number of florets per spike and number of florets opened at a time. The interaction effect (I x F) was not found significant in all the above cases.
Key words :
Fertigation, flowering parameters, gladiolus, growth parameters, moisture regimes.
