An experiment was conducted to study the effect of integrated use of chemical fertilizers, biofertilizers and biostimulants on growth, flowering and corm production in gladiolus (Gladiolus grandiflorus L.) cv. Sancerre at the Floriculture Research Farm, Punjab Agricultural University, Ludhiana during the year 2006–07. The experiment was laid out in randomized block design with eighteen treatments. Analysis of results revealed that maximum plant height (101.2 cm), spike length (88.2 cm), rachis length (62.4 cm), number of florets per spike (14.4), average corm weight (36.0 g), leaf and soil NPK (2.27%, 0.18%, 3.38% and 99.9 kg/ha, 34.2 kg/ha, 165.3 kg/ha) was recorded in the treatment T₁₇. Duration of flowering (11.4 days), size of floret (10.5 cm), number of corms per plant (2.3), number of cormels per plant (25.6) and 100-cormel weight (24.5 g) was found maximum in treatment T₁₆. However, treatments did not have any significant influence on days taken to flowering and number of florets opened at one time.
