ABSTRACT
A field experiment was conducted to study the effect of integrated nutrient management and corm size on growth, yield and quality of flowers and corms (Gladiolus grandiflorus L.) cv. Picardy at Floriculture section Deptt. of Horticulture, University of Agricultural Sciences, GKVK, Bangalore, during kharif 2013-14 with three replications and fifteen treatment combinations. The results indicated that VAM+ Azospirillum + Azotobactor +large size + RDF (T15) gave more spikes both grade I (89982) and grade II spikes (33281) and number of corms (284722) and revenue of grade I (629874), grade II (166405) spikes and corms (1423610) also more in T15. Highest gross returns was registered in VAM+ Azospirillum +Azotobactor +large size + RDF (` 2219889), which was on par with VAM+ large size + RDF an (` 2068030) was lowest in small size corm + RDF (` 1099825). Net returns also differed significantly due to treatments. Highest net return was registered in T15 (` 1741953), which was followed by T6 (1590094). Net returns was lowest in control (621889). The benefit:cost ratio differed significantly due to treatments. Highest B:C ratio was registered in T15 (4.64), but it was on par with T6 (4.32), T12 (4.03). The B:C ratio was lowest in small size corm+ RDF (2.30).
Key words :
Cost : benefit ratio, Gladiolus, Growth & yield parameters, INM, Nutrient levels, Seed production.
