RESPONSE OF DIFFERENT SPACING AND SALICYLIC ACID LEVELS ON GROWTH AND FLOWERING OF GLADIOLUS (Gladiolus grandiflora L.)

An experiment was conducted to assess the effect of spacing and salicylic acid levels on vegetative growth and flowering of gladiolus cv. White Properity at HRC, SVPUAT, Meerut. The three levels of spacing (20×10, 20×20, and 20×30 cm) and three levels of salicylic acid (0, 50 and 100 ppm) were used in randomized block design (RBD) with three replications. Out of these a optimum spacing 20×20 cm was found superior with 100 ppm salicylic acid concentration in respect of number of leaves, leaf length (cm), days to opening of 1st floret and visibility of first spike, spike length, and number of florets per spike.
