Varietal response and effect of Trichoderma on flowering in gladiolus

Abstract

A field experiment on evaluation of gladiolus varieties and see the effect of Trichoderma on flowering parameters was carried out at Horticulture Research Farm, Department of Horticulture, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, (U.P.), during 2017-2018. Eight varieties of gladiolus i.e. Yellow Jester, Tiger Flame, Punjab Morning, Punjab Dawn, Pusa Kiran, Shubhangini, IIHR, and Dhanvantri. These varieties treated with Trichoderma and untreated (control). Thus there was sixteen treatment combinations. Experiment was laid out in Randomized Block Design with three replications. Application of Trichoderma influenced some flowering parameters. Trichoderma significantly influenced length of spike and duration of flowering, but there was no any significant effect of Trichoderma on days to spike emergence, opening of first floret, and number of floret per spike. Among different varieties cv. IIHR was earlier to days to spike emergence and opening of 1st floret which was at par with cv. Pusa Kiran. The number of florets per spike was recorded maximum in cultivar Pusa Kiran. Cv. Pusa Kiran also registered maximum length of spike. The maximum duration of flowering was recorded in cultivar Shubhangini.
