Genotype variations in biomass production and nutrient removal pattern in gladiolus raised from cormels

The present study was conducted at ICAR-IIHR, Bengaluru, India during 2018-2019 to quantify resource use efficiency in 11 genotypes of gladiolus propagated through cormels based on growth, biomass partitioning and nutrient removal pattern. Growth yield parameters differed significantly among genotypes. leaf number higher Arka Shobha (9.67) Manorama (9.00) than other (6.33-8.67). spike length Naveen (102.9 cm) lesser Kumkum (66.2 cm). pattern indicated that below ground (corm) accounted for 71.5% total (3990 kg ha-1), while above (leaf spike) 28.5% (1137 ha-1). In genotypes, the profile accumulation N corms followed by leaves spikes. P (0.13-0.14%), Mn (29.8-43.5 mg kg-1), Zn (15.3-23.4 kg-1) Cu (5.2-6.0 similar. Spikes accumulated K Mg corms. Ca more (2.39%) flower stalks (1.95 %). average Fe concentration (mg (293) (269) (160). quantified 122 N, 10.8 71.7 per ha crop. demand (g ha-1) (1062.4) (152.5), (23.8) (23.0). data implies is a heavy feeder K. Nutrient influenced production with high degree variability (Y =-541.858 + 24.097 Kuptake 1.405 Feuptake R2=0.995). gives scope precision avoiding blanket recommendations.
