Abstract
A field experiment was conducted during winter season of 2014-15 to study “Effect of genotype and planting geometry on vegetative growth, flower yield and quality of Gladiolus (Gladiolus x hybridus Hort.)” having 12 treatment combinations of two genotypes (V1- American Beauty and V2- Psittacinus Hybrid-1) and six spacings (S1- 15 cm x 15 cm, S2- 20 cm x 20 cm, S3- 30 cm x 15 cm, S4- 30 cm x 20 cm, S5- 30 cm x 30 cm, S6- 40 cm x 30 cm) laid out in factorial randomized block design with three replications at College of Horticulture & Forestry, Jhalawar (Raj.). The treatment V1S4 (American Beauty + 30 cm x 20 cm spacing) recorded the maximum plant height (124.13 cm), longest spike length (100.93 cm), maximum Rachis length (61.73 cm) while the treatment V1S6 (American Beauty + 40 cm x 30 cm spacing) recorded the highest number of leaves per plant (8.00), longest leaves (35.33 cm), maximum stem diameter (1.26 cm), highest number of florets per spike (15.60), maximum spike girth (0.89 cm), largest florets (9.84 cm diameter), maximum number of florets opened at a time in field (5.93) whereas V2S1 (Psittacinus Hybrid-1 + 15 cm x 15 cm spacing) recorded the minimum values for these characters. The treatment combination V2S6 (Psittacinus Hybrid-1 + 40 cm x 30 cm spacing) had the maximum number of spikes per plant (2.33) and minimum was recorded in V1S1 and the treatment combination V2S1 (Psittacinus Hybrid-1 + 15 cm x 15 cm spacing) had the maximum number of spikes per plot (90.33).
