Effect of biostimulants and biofertilizers on growth, flowering and quality of gladiolus (Gladiolus grandiflorus L.) Cv. American beauty under greenhouse conditions

Abstract

The present experiment entitled “Effect of biostimulants and biofertilizers on growth, flowering and quality of gladiolus (Gladiolus grandiflorus L.) cv. American Beauty under greenhouse conditions” was carried out at High Tech Horticulture Park, Department of Horticulture, College of Agriculture, Junagadh Agricultural University, Junagadh during 2015-2017. The experiment was laid out in Factorial Completely Randomized Block Design (FCRD) consisting two factors with three repitations. Four treatments of biostimulants and three treatments of biofertilizers were considered as treatment combinations. The results indicated that application of humic acid 0.2% with Azotobacter @ 2.5 ml/plant + PSB @ 2.5 ml/plant + KSB @ 2.5 ml/plant at first spray at 30 DAP, second spray at 45 DAP and third spray at 60 DAP of biostimulants and soil application of biofertilizers at the time of planting and two month after planting gives higher vegetative growth, flowering and quality parameters in gladiolus.
