Abstract
The present investigation entitled “Effect of N and K fertilization on vegetative growth of Acroclinium (Helipterum roseum)” was carried out at the laboratory of floriculture and experimental farm of Mata Gujri college, Fatehgarh Sahib, Punjab. The experiment was laid out in randomized block design (RBD) with twelve treatments and three replications. The treatments were T1 i.e., 125 kg/acre urea + 60 kg/acre MOP, T2 i.e., 175 kg/acre urea + 60 kg/acre MOP, T3 i.e., 225 kg/acre urea + 60 kg/acre MOP, T4 i.e., 125 kg/acre urea + 80 kg/acre MOP, T5 i.e., 175 kg/acre urea + 80 kg/acre MOP, T6 i.e., 225 kg/acre urea + 80 kg/acre MOP, T7 i.e., 125 kg/acre urea + 0 kg/acre MOP, T8 i.e., 175 kg/acre urea + 0 kg/acre MOP, T9 i.e., 225 kg/acre urea + 0 kg/acre MOP, T10 i.e., 0 kg/acre urea + 80 kg/acre MOP, T11 i.e., 0 kg/acre urea + 60 kg/acre MOP and T12 i.e., control. Observations were recorded for vegetative, flowering and seed yield parameters. Among all treatments maximum plant height (44.86 cm and 59.91 cm ), leaf length (5.01 cm and 5.33 cm), plant spread (17.68 cm2 and 32.37 cm2) and diameter of main stem (6.13 mm and 10.77 mm) were found maximum in T3 i.e., 225 kg/acre urea + 60 kg/acre MOP and maximum number of leaves per stem (37.28 and 54.98) and number of leaves per plant (645.67 and 1055.13) was observed in T9 i.e., 225 kg/acre urea + 0 kg/acre MOP at 45 and 90 days respectively. Best vegetative parameters were recorded in 225 kg/acre urea + 60 kg/acre MOP and 225 kg/acre urea + 0 kg/acre MOP are best dosage for Acroclinium flower.
