The present investigations were carried out at the experimental farm of Department of Seed Science and Technology, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan, HP during 2014–2015. The experiment was laid out in a randomized block design (factorial) with 5 levels of nitrogen viz N1(10 g N/m2), N2(15 g N/m2), N3(20 g N/m2), N4(25 g N/m2), N5(30 g N/m2) and 4 levels of potassium viz K1(5 g K/m2), K2(10g K/m2), K3(15 g K/m2) and K4 (20 gK/m2). All 20 treatment combinations of nitrogen and potassiumwere replicated thrice. Amongdifferent levels of nitrogen N5 (30 g N/m2) recorded maximum values for plant height (59.44 cm), stem length (46.17 cm), stem diameter (22.07 mm) and head size (15.89 cm). However minimum number of days taken for head formation of cut stems (65.33 days) and colour development (78.33 days) was recorded with the lower level of nitrogen ie N1 (10 g N/m2). Maximum plant height (51.30 cm), stem length (38.50 cm), stem diameter (18.42 mm) and head size (14.26 cm) were recorded with the application of K3 (15 g K/m2). However minimum number of days taken to head formation (72.80 days) was recorded in treatment K1 (5 g/m2) and for colour development (85.53 days) in K4 (20 g K/m2).
