Influence of nitrogen levels and plant geometry on growth, flowering and seed production in pansy (Viola tricolor Hortensis) variety snow white

Author(s):

Abstract:
A field experiment on the effect of nitrogen and plant geometry on growth, flowering and seed production in pansy (Viola tricolor) variety ‘Snow White’ was conducted. Four doses of nitrogen (0, 15, 20 and 25 g/m2) and three levels of spacing (15x15cm, 15x20cm and 15x25cm) were tested in Factorial Randomized Block Design with three replications. The analyzed data indicated that the values of plant height, number of leaves per plant, leaf area, flower diameter, number of capsules per plant and seed yield were the highest at 20g N/m2. The values of plant spread, early flowering, number of flowers, flower duration, pedicel length and number of seeds per capsule were the maximum at 25 g N/m2 and was statistically at par with 20g N/m2. The maximum plant spread, number of leaves, number of flowers per plant, flower duration, flower diameter, number of capsules and seed yield per plant was recorded at the widest spacing (15x25 cm). Significant effect of interaction was observed in all the parameters except 1000-seed weight.
